MAM Glass Baby Bottles Review

Choosing the right baby bottle can feel overwhelming – especially for parents who want a safe, high-quality option that babies will love. One brand that often comes up in the conversation is MAM, known for its innovative pacifiers and bottles.

In this deep dive, we’ll explore MAM as a company (their mission and history) and take a close look at MAM’s glass baby bottles – including their design, materials, and special features. We’ll also discuss how these bottles work with different nipples and accessories, what real parents are saying on social media, third-party safety testing results, a quick comparison to other glass bottles on the market, and details on pricing and where to buy.

Our goal: to provide informative and parent-friendly insights for anyone searching for the best glass baby bottle options.

About MAM: Brand Background & Mission

MAM was founded in 1976 in Vienna, Austria by Peter Röhrig, a plastics engineer with a vision to create baby products that blend attractive design with proven medical benefits.​

The first product he launched was a pacifier, and from those early days MAM’s core mission has been combining function, style, and top-tier safety in all its baby gear. Over 45 years later, MAM has grown into a global company (now selling in over 60 countries) but remains focused on the well-being, health, and safety of babies.

MAM’s philosophy can be summed up by their motto: “We love babies. So we believe that only the best is good enough for your baby!”.​

Every product is developed with input from medical experts (pediatricians, dentists, developmental psychologists, etc.) to ensure it supports babies’ healthy development​

This science-backed approach and commitment to quality have made MAM a trusted name among parents for decades.

In short: MAM is a company with deep roots in baby care innovation and a clear mission to make life easier for babies and parents through safe, well-designed products​.

Now, let’s zoom in on one of those products – the MAM glass baby bottle – to see what it offers.

MAM’s Glass Baby Bottles (“Feel Good” line) – Design, Materials & Features

MAM’s primary glass bottle offering is known as the “Feel Good” Glass Baby Bottle. These bottles are designed to be both user-friendly and baby-friendly, with a focus on safety and comfort. Here’s a detailed look at their design and features:

• High-Quality Glass Construction: The bottles are made from premium, temperature-resistant glass. This means they can handle rapid temperature changes – you can safely heat them in a bottle warmer or microwave and cool them down quickly without cracking. The glass is durable and stain- & odor-resistant, so it won’t absorb colors or smells from formula or milk​. And of course, being glass, they are 100% free of BPA, BPS, or any plastics – giving many parents peace of mind about chemicals. (MAM also notes that their glass is recyclable and more eco-friendly than plastic.)
• Sizes Available: MAM’s glass bottles come in three sizes to adapt as your baby grows. In the U.S., you’ll commonly find a 6 oz (170 ml) size and a 9 oz (260 ml) size​. In some markets, MAM even offers a small 3 oz (90 ml) version for newborns or small feeds​. The 6 oz bottle is great for newborns and young infants, while the 9 oz can hold larger volumes for older babies. (Internationally, an even larger ~11 oz/330 ml version is sometimes available, though it’s not as widespread.) Regardless of size, all bottles share the same width and design style.
• Wide Neck & Easy to Clean: The bottles have a wide neck and wide opening, making them easy to fill and clean. Parents often appreciate that you can fit a bottle brush in easily, and there are no hard-to-reach corners. The simplicity of the design – basically just the bottle, a nipple, and a ring plus cap – means fewer pieces to wash compared to some complex anti-colic bottles.

• Unique Flat-Shaped Nipple (“Teat”): Each MAM glass bottle comes with MAM’s signature SkinSoft silicone nipple, which has a distinctive flat shape. When you look at it from the side, it’s not round like many bottle nipples, but rather flat and symmetric – designed to mimic a mother’s nipple in the mouth during breastfeeding​. According to MAM, this shape feels very familiar to babies and can help breastfed babies transition between breast and bottle more easily​.
• In fact, a large market study by MAM claims that 94% of babies accept the MAM bottle nipple​ – a high acceptance rate that many exhausted parents of picky babies will be happy to hear about! The nipple is also very soft (they call it “ultra soft” with a silky texture) to further replicate the natural feel​.

• Vented for Anti-Colic: The nipple itself is vented to allow air flow and prevent a vacuum, which helps reduce gas/colic. While MAM’s plastic bottles have a special vented base, these glass bottles do not have a separate venting system in the base – instead, they rely on the one-way valve in the nipple to let air in as baby drinks (preventing the nipple from collapsing and aiming to reduce air swallowing). This simpler design means you don’t have extra parts (no separate vent insert or ring to deal with). It’s effective for many babies, though as we’ll discuss later, a few parents of especially colicky infants note a difference between the glass and MAM’s dedicated anti-colic plastic bottles.

• Protective Cap with Measuring Marks: Each bottle comes with a spill-proof dust cap that doubles as a measuring cup​. The cap has small volume markings on it, which is a neat little feature if you need to measure out small amounts of liquid (like medicine or a tiny top-up feeding). It snaps on securely to prevent leaks when you’re out and about. In fact, the MAM bottle is designed to be leak-proof just with the cap – unlike some bottles, you don’t need a separate travel disk to seal it; simply pop on the cap and you’re good to go​.
• Safe Materials: Naturally, all components of the MAM bottles are made from baby-safe, non-toxic materials. The glass is lead-free (more on third-party testing later), and the nipples are made of medical-grade silicone (latex-free). MAM states that their bottles are BPA and BPS-free in line with global safety standards. The bottles also meet or exceed U.S. safety regulations (such as CPSC/CPSIA standards)​.
• Design Aesthetics: In terms of looks, MAM glass bottles are typically transparent with measurement markings and the MAM logo printed on the side. They often come with different colored caps/rings – for example, you might find them with a neutral cream color (as sold at Target), or other colors/themes in international versions (some versions have cute prints like small animals or graphic patterns, often labeled by code like “Design A, B, C”). The style is relatively minimalist and modern. (One nice thing: the measurement markings are etched/printed in paint that is non-toxic, so they are safe and also don’t easily wear off.)

• Heat and Sterilization Friendly: The MAM Feel Good glass bottles are built to handle heat. You can sterilize them in boiling water or a steam sterilizer, and they’re dishwasher-safe for cleaning​. You can even microwave them (just the bottle portion, not with the nipple/ring on) to warm milk, though as always you should remove the nipple and cap before microwaving​. Unlike MAM’s plastic bottles, the glass ones do not have the special “self-sterilizing” microwave feature (where the bottle can be converted into a mini-sterilizer) – that feature is unique to the MAM Easy Start plastic anti-colic bottles. With glass, you’ll use traditional sterilization methods.

In summary, MAM’s glass bottles are sturdy, easy-to-use wide-neck bottles made of top-quality glass, paired with an especially baby-friendly nipple design. They aim to provide a natural feeding experience for baby while offering parents the benefits of glass (hygienic, chemical-free, easy to clean). Now, let’s talk about how these bottles work with various nipples and accessories, because as your baby grows you might want to mix-and-match parts or use different flows.

Nipples, Flow Options, and Compatibility with Accessories

One big question parents have is: What nipples can I use with these bottles? And possibly, are they compatible with other accessories or bottle systems I already have?

MAM Nipple Sizes: MAM has developed an array of six different nipple sizes/flow rates for their bottles​.

This is more than many brands, which often have 3 or 4 flows. The idea is to perfectly match the nipple hole size to your baby’s stage and the liquid’s thickness​.

The typical lineup includes:

• Size 0 – Extra slow flow (for premature or very newborn babies, or for breastfed newborns who need a very slow pace).
• Size 1 – Slow flow (0+ months, comes standard with the 6 oz newborn bottle​).
• Size 2 – Medium flow (2+ months, comes with the 9 oz bottle).
• Size 3 – Fast flow (for older babies, maybe 4-6+ months).
• Size 4 or X – Extra fast or cross-cut for thick liquids (like if you start adding a little baby cereal to the bottle or for very hungry older babies).
• Size Y (if applicable) – MAM at one point also had a “variable” flow or a specific spout for thicker formula – the naming can vary, but essentially up to six choices exist. (The exact lineup can depend on region, but the key takeaway is MAM offers a very granular progression of nipple flows to suit babies at different stages.)

The good news is that all MAM bottle nipples are interchangeable with MAM bottles. The glass bottles use the same nipple and ring system as MAM’s other bottles, so you can buy a faster-flow MAM nipple later and it will fit the same threads, no problem. For example, many parents with a newborn will use the slow Size 1 that came with the bottle, then at around 2-3 months, move up to Size 2 or 3 as needed, without having to buy new bottles – just the new nipples. MAM nipples are widely sold in packs (usually 2-packs) so it’s easy to upgrade the flow. (Important: Remember to replace silicone nipples every so often anyway – they can wear out or get damaged over time​)

Bottle Components: Each MAM bottle has three main parts (plus the cap): the bottle itself (glass), the silicone nipple, and a plastic screw ring that holds the nipple in place. There is also a locking cap as discussed. MAM does not use a separate sealing disk in the glass bottles, since the cap serves that function when snapped on tightly​.

Accessories (Handles, etc.): MAM sells some bottle-related accessories like handles that can be attached to their bottles (useful when baby is a bit older and wants to try holding the bottle independently). These handles typically slip on beneath the ring. According to some parent reports, the MAM trainer handles do fit the glass bottles because the diameter is the same as the plastic ones. (Always verify compatibility if buying a specific MAM accessory, but generally MAM’s wide bottle designs share components.) The company also offers things like bottle brushes, sterilizers, and of course pacifier clips that complement their feeding products, though those aren’t specific to the bottle’s function.

It’s worth noting that MAM’s glass bottles are not “anti-colic” in the same way as their Easy Start Anti-Colic plastic bottles, which have a vented base. The glass bottle’s anti-colic mechanism is just the vented nipple. So you cannot add an “anti-colic base” to the glass bottle – that part isn’t compatible, as the glass bottle doesn’t have a removable bottom. If your baby has a lot of gas issues, you might consider that difference. However, many parents find the vented nipple on the glass bottle is sufficient for comfortable feeding (we’ll see what reviews say in the next section).

Compatibility with Other Brands: Here’s an interesting aspect – some resourceful parents have experimented with mixing and matching bottle parts to suit their baby’s preferences. In discussions on forums and Reddit, a few caregivers have found that MAM bottles can fit certain other brand nipples of similar width. For instance, one parent shared that they use Evenflo Balance+ wide nipples on MAM glass bottles and it “fits perfectly” (the threading and sizing of the collar lined up)​.

Another mentioned using Lansinoh NaturalWave nipples with MAM bottles​, and yet another uses Pigeon brand nipples with the MAM glass bottle​.

The ability to cross-use nipples might be useful if your baby happens to prefer a specific nipple shape (say, from a different bottle you tried) – you might not have to ditch your MAM glass bottle; you could potentially use that favored nipple on it. Of course, MAM designs their own nipple to be optimal, so ideally you’d use the MAM nipple. But it’s nice to know the bottle’s opening is a standard wide size that offers some flexibility.

On the flip side, MAM nipples themselves can sometimes be used in other bottles. Some users report sticking MAM nipples into bottles like Philips Avent or Dr. Brown’s Wide-Neck. Your mileage may vary, but generally wide-neck bottles have similar circumference, so there is some interchangeability in the baby bottle world. This is not officially endorsed by manufacturers, but parents have been known to get creative to find what works for their baby!

Summary: MAM glass bottles work seamlessly with all MAM silicone nipples (Sizes 0 through 3+/X) and basic accessories like MAM handles. They don’t require any extra parts to be anti-colic (aside from the built-in nipple vent). And while not advertised, the bottles’ standard wide-neck design means you may use other brand nipples if needed, though most babies take well to the MAM nipple itself.

Now, beyond the specs and compatibility, let’s hear from those with real-world experience: What are parents saying about MAM’s glass bottles?

Real Parents’ Feedback: What Social Media Reviews Say

To get a well-rounded perspective, we scoured social media and parenting forums (Instagram, Facebook, Reddit, etc.) for authentic customer reviews of MAM glass baby bottles. Overall, feedback is very positive, but there are also a few critiques worth noting. Here we compile some of the common themes from real moms and dads:

👍 Things Parents Love:

• Easy to Clean & No Stinky Residue: A huge number of parents rave about how easy MAM glass bottles are to wash. Because the glass doesn’t hold onto odors or colors, and the wide opening lets you scrub every corner, cleaning is a breeze.
• One Reddit user from the UK said: “We use the MAM glass bottles. Work great and easy to clean. No leakage. No mess with all the parts the plastic bottles have.” This sentiment – “easy to clean, no leaks” – comes up frequently. Parents also love not seeing any cloudiness (which often happens over time with plastic bottles).
• Fewer Parts & No Leaks: Unlike some anti-colic bottles that have multiple pieces (vents, inserts, etc.), the MAM glass bottles are straightforward. Several caregivers mentioned appreciating the simplicity.
• The quote above highlights “no mess with all the parts the plastic bottles have”​ – referencing that MAM’s plastic anti-colic bottles have a vented bottom that can leak if not assembled just right, whereas the glass design is just a normal one-piece bottom.
• Many say they never experience leaks with the glass MAMs as long as the nipple and ring are secured (and the cap is on when shaking). This reliability is a big plus when you’re throwing a bottle in the diaper bag.
• Baby Accepts the Nipple: A lot of parents report that their babies took to the MAM nipple without fuss, even if they initially refused other bottles.
• For example, one mom on BabyCenter wrote that MAM was the only bottle her breastfed baby would consistently accept, and she liked that the measurement markings helped track intake (especially helpful when supplementing breastfeeding and wanting to know ounces)​.
• The high acceptance rate claimed by MAM (94% of babies) seems to reflect in many real-world experiences – particularly for babies who used MAM pacifiers, since the bottle nipple has a similar flat shape which those babies are already used to. Parents who struggled with nipple confusion or bottle refusal often express relief once they tried MAM.
• Quality and Safety Reassurance: Many parents specifically sought out glass bottles for health reasons and ended up with MAM.
• They mention feeling good about the fact that there’s no plastic touching the milk, and they often reference that MAM’s paint/markings are free of lead and toxins. In one Reddit discussion among naturally-minded parents, a user said: “We use the MAM glass bottles, I really love them! They test negative for lead.”
• Knowing that an independent test found no lead in MAM’s painted logos (more on that soon) gave a lot of parents peace of mind, especially after some news that other brands had issues with lead in external paint. Also, multiple reviewers noted no weird chemical smells when first opening the package (sometimes plastic bottles have a smell initially).
• Sturdy (for Glass): While glass bottles can and do break if dropped on a hard floor, several parents commented that MAM glass bottles seem thick and durable.
• A few mentioned accidental drops on a counter or gentle falls that didn’t shatter the bottle (though this is anecdotal – we don’t recommend testing the limits!). MAM states the glass is tempered and high-quality​, and many users felt it’s less fragile than they expected.
• Of course, it’s still glass, so folks advise using a silicone sleeve or just being careful on hard surfaces.
• Aesthetics & Measurements: Parents generally find the bottles cute and nicely designed – the simplicity and occasional printed graphics are pleasing but not over-the-top. And practically speaking, the measurement marks are accurate and easy to read, which isn’t always the case on curvy bottle shapes.
• One parent said it “would drive me crazy not knowing how much [my baby] was drinking” with other setups, but MAM’s clear markings solved that for her​. The little measuring cap also got shout-outs for being handy when mixing small formula amounts or travel feeding.

👎 Things to Consider (Cons Reported):

• Heavier and Breakable: This is true of any glass bottle – they weigh more than plastic, and if you drop them on tile or concrete, they can break. A few parents noted that the MAM glass bottles are a bit heavier for baby to hold on their own.
• By the time a baby is old enough to try holding their bottle (say 6+ months), some may struggle with the weight of glass vs a lightweight plastic. Using handles can help, but it’s a consideration. And of course, you have to be more careful about not dropping/throwing them.
• One mom mentioned she switches to plastic when traveling to avoid potential breakage, but uses glass at home. MAM does confirm “glass may break” if dropped – it’s not shatter-proof like some plastic​.
• No Advanced Anti-Colic Vent (Some Babies Get Gassy): This point is a bit of a debate among parents. Several users whose babies are very gas-prone or colicky observed that MAM’s glass bottles didn’t reduce air swallowing as much as some specialized anti-colic bottles.
• One Reddit reviewer from the UK said: “We tried the MAM glass bottles … and they made my little one very gassy as there was no [air] release like the plastic bottles have.” By “release” they are referring to the venting system; the MAM Easy Start plastic bottles have a vented base that equalizes pressure extremely well, whereas the glass bottle relies only on the nipple vent.
• That parent ended up switching back to a bottle with a dedicated vent system for their baby’s tummy issues.
• However, many others report their babies have no issues with gas using MAM glass – including some who specifically said their baby was less gassy with MAM than with Dr. Brown’s! It likely depends on the baby. If you know your little one is very sensitive to air intake, you might need to burp them more often with the MAM glass bottle, or consider a hybrid approach (using a vented bottle during the gassiest stage, then transitioning to MAM glass when they’re a bit older).
• On the flip side, some parents deliberately chose MAM glass to avoid the hassle of vent systems – “No leakage, no mess with all the parts the plastic bottles have,” as one parent happily put it​. So, the anti-colic performance gets mixed reviews: generally good, but not as foolproof as bottles explicitly designed for colic relief.
• Cost (Especially Historically): Price came up in a few discussions. MAM glass bottles have sometimes been hard to find in certain countries (notably the US until recently), and they were expensive when only available via import. One parent in 2021 noted it was costing about $16 per bottle from the MAM website or up to $30 per bottle on Amazon (third-party sellers) in the US​.
• The word “expensive” appears in a few reviews, with people comparing it to ~$7-8 for Dr. Brown’s glass or <$5 for an Evenflo glass bottle. The good news is that as of now, MAM glass bottles are more widely available in North America (for example, at Target for about $12-13 each​), so the price has come down to be more in line with other premium bottles. They are still pricier than basic bottles, and if you need to buy several, it adds up. However, many parents felt it was worth it for the quality. Some mitigated cost by putting MAM bottles on their baby registry or buying a gift set (MAM sells a 3-pack gift set that can be a better value​).
• Availability (Limited Colors/Options): While not a major complaint, a few parents mentioned they wished there were more color choices or decorative options in the MAM glass line. The plastic MAM bottles sometimes come in cute prints or multiple colors, whereas the glass ones have more limited designs (often just a plain print or one color of cap). This is a minor “con,” but if you love coordinating baby gear, the selection for MAM glass is relatively modest. Also, in some areas, you might only find them online and not in local stores. (This is rapidly changing, though – for example, Target and Walmart’s websites now list MAM glass bottles, whereas a few years back they were almost unheard of in U.S. stores.)
• Bottle Width Compatibility: One or two users noted that because MAM bottles have a wide neck, they didn’t screw directly onto certain breast pumps for pumping milk into (some pumps are made to fit standard/narrow bottles like Medela or Dr. Brown’s narrow).
• This is a universal issue – you may need an adapter if you want to pump directly into a wide-mouth bottle. MAM doesn’t seem to sell a pump adapter themselves, so you’d have to look for a generic wide-to-narrow pump adapter if that’s a need. Otherwise, you can always pump into the bottles that come with your pump and transfer into the MAM for feeding.

Overall, the pros far outweigh the cons in parents’ eyes. The recurring themes are that MAM glass bottles are safe, easy, and baby-approved. The main cautions are typical of any glass bottle (be careful with breakage) and the slightly less aggressive anti-colic venting (which only a subset of parents found to be an issue).

To wrap up the feedback section, here’s a quick Pros and Cons list distilled from real customer experiences:

Pros and Cons of MAM Glass Baby Bottles (According to Parents)

Pros:

• Safe, Non-Toxic Materials: Made of high-quality glass with no BPA, BPS, or other harmful chemicals. Paint on bottle has no detectable lead (third-party tested), giving peace of mind about safety.
• Easy to Clean: Wide neck and simple design means no fiddling with tiny parts. Doesn’t retain smells or stains​. Most parents find cleaning these much easier than multi-part anti-colic bottles​.
• Breastfeeding-Friendly Nipple: The flat, soft nipple is accepted by an extremely high percentage of babies​. Great for breastfed babies transitioning to bottle – many report no nipple confusion and easy switching between breast and MAM bottle.
• Less Nipple Collapse: The vented nipple allows for smooth milk flow without the nipple caving in. Babies can maintain their latch and rhythm more easily, which means less frustration during feeds.
• No Leaks (Secure Design): The well-fitting nipple ring and included cap ensure it’s virtually leak-proof when assembled correctly. Easy to shake/mix formula in the bottle without spills. No separate sealing disc needed for travel​ – just pop on the cap.
• Durable & Heat-Resistant: Tempered glass that can handle quick temperature changes​. Safe for dishwasher and sterilization. Markings don’t scrub off easily. Many users find the glass surprisingly sturdy (some minor drops didn’t break it, though caution is still advised).
• Versatile Sizing: Available in multiple sizes (small to large) to grow with baby’s needs. You can start with a little 3oz for newborn if available, and move up to 6oz and 9oz as baby’s appetite increases.
• Wide Compatibility: Works with all MAM nipple sizes (0 through 3+, easy to swap as baby grows). Can attach MAM handles for older babies learning to hold the bottle. Some other brand wide-neck nipples also fit, if needed, giving flexibility​.
• Trusted Brand & Research-Based: MAM’s 40+ year reputation and medical expert collaboration means these bottles were thoughtfully engineered. Parents often trust MAM because of their positive past experiences with MAM pacifiers or other products.
• Stylish Look & Functional Details: Sleek design that many find attractive. Measurement lines are clear. The cap doubling as a measuring cup is a clever bonus​ for precise mixing of small quantities (e.g., preparing formula for a newborn who drinks tiny amounts).

Cons:

• Heavier than Plastic: Being glass, the bottle is a bit heavier for both parent and baby to hold. As baby gets older, they might struggle to grip it for long. It’s also not as travel-friendly if you’re worried about weight or dropping.
• Breakable: If dropped on a hard surface from height, it can shatter (as with any glass). Requires careful handling – you may want to invest in silicone sleeves for grip/protection or have plastic backups for high-risk situations (like in the car or at daycare).
• Limited Venting vs. Anti-Colic Bottles: Does not have an advanced anti-colic vent system beyond the nipple vent. A small number of parents found their very gassy babies had more burps/spit-up with the MAM glass compared to using something like a Dr. Brown’s vented bottle​. Most babies do fine, but if yours has severe colic, you might need to monitor and burp frequently or use a specialized bottle.
• Moderate Price Point: Costs more than basic bottles. Typically around $12+ per single bottle at retail​. Not exorbitant, but if you need a bunch, the cost adds up (especially compared to cheap Evenflo glass bottles). Multi-packs or sales can help. In the past, availability issues made them very expensive in some regions​, though that’s improving now.
• Availability (Varies by Region): Depending on where you live, MAM glass bottles might not be stocked in local stores. In the U.S., they are now at Target and some others, but a couple of years ago they had to be ordered online. If you’re outside of Europe or North America, you might have to check specialty baby shops or order internationally. Also, fewer color/design options compared to some competitors – mainly neutral designs.
• No Self-Sterilizing Feature: Unlike MAM’s plastic anti-colic bottles, the glass ones can’t be used to self-sterilize in a microwave (since they lack the vented base needed for that function). Not a huge con (you can sterilize them other ways), but if you were a fan of MAM’s unique microwave trick, note that it’s not applicable to the glass line.
• Pump Compatibility: The wide neck might not attach to all breast pumps without an adapter. If you plan to pump straight into the bottle, you may need a separate adapter piece for certain pumps (e.g., Medela, Spectra). This is a common issue with wide bottles and not unique to MAM, but worth mentioning.

That covers the pros and cons as reported by real users. Next, we’ll address the important topic of safety testing – are there any third-party results on these bottles being “nontoxic”? What about things like lead, cadmium, etc.? Let’s find out.

Safety and Nontoxic Testing Results

One of the reasons many parents opt for glass bottles is to avoid potential chemicals leaching from plastic. But even glass bottles can have concerns – chiefly, the paint used for measurement markings or logos could contain toxic heavy metals like lead or cadmium. In recent years, there have been some alarming reports of certain brands of glass baby bottles having lead in exterior paint (for example, there was a recall of some Avent natural bottles for a lead-paint issue, and tests found old NUK bottles with leaded logos). So, it’s completely valid to ask: Are MAM glass bottles truly non-toxic and safe?

The answer, thankfully, is yes – MAM’s glass bottles have passed third-party testing with flying colors. Here are some key points on safety:

• Lead Safe Mama Testing: An independent consumer advocate and testing group known as Lead Safe Mama (Tamara Rubin) has tested dozens of baby bottles with XRF analyzers for lead and other metals. MAM’s glass bottle was tested and found to be lead-free in all components.
• In fact, in a roundup of top picks in Feb 2024, Lead Safe Mama listed the MAM Feel Good Glass Baby Bottle as having “no detectable lead” in both initial and repeat tests​. This means the paint used for markings and any colored decals had 0 detectable lead. (For context, they often find some bottles with 1-2 ppm or more, so a true non-detect is excellent.)
• Mamavation/DetectLead Study: Another group of investigators partnered with a lab to test various bottles for lead and other toxins. They reported similarly that MAM’s glass bottles had no detectable heavy metals on the glass or painted areas​. This matches the Reddit chatter we saw where parents were sharing which bottles tested safe – MAM was on the safe list along with a few others like Evenflo and Lansinoh’s newer batches.
• No BPA/BPS or Phthalates: By definition, glass doesn’t contain BPA or phthalates (those are chemicals used in plastics). All the non-glass components (like the nipple and ring) are made of BPA-free materials. MAM’s packaging and website explicitly state the bottles are 100% BPA and BPS free​. These bottles also meet EU and US standards that ban those substances in baby products, and they carry certifications that they comply with CPSIA (Consumer Product Safety Improvement Act) requirements.
• Overall Chemical Safety: Consumer Reports did a study in 2020 and found no detectable BPA, lead, or phthalates in any of the 9 baby bottles they lab-tested​consumerreports.org. (MAM wasn’t named in the snippet we saw, but the general takeaway is that modern baby bottles from reputable brands are generally safe from these toxins due to improved regulations and testing.) MAM being a reputable European brand likely undergoes strict quality control. Additionally, MAM bottles are free of PVC and other plasticizers – there’s an FAQ noting MAM doesn’t use those in any bottle parts.
• Thermal and Mechanical Safety: Because MAM’s glass is strong and temperature-resistant, it’s less likely to crack due to heating/cooling (always follow instructions and avoid pouring boiling water directly in any bottle to be safe). The bottles have been tested for pressure changes – normal use like warming, refrigerating, etc., is fine. Just avoid extreme sudden temperature swings (e.g., freezer to boiling water) as with any glass.
• The nipples are also safety-tested for things like tensile strength (so they won’t tear apart in baby’s mouth under normal use). Always inspect silicone nipples for wear and replace them if you see any cracks or thinning​.
• Choking/Leak Safety: The design of the nipple and ring ensures that even if the bottle is turned upside down with cap off, the nipple doesn’t just fall out (a safety flange keeps it in place). And with the cap on, it’s leak-proof, which also means if you store milk in it, it’s not exposing anything to air. MAM’s cap being tight-fitting acts as a safety seal for transport​ – which indirectly is a safety feature (no surprise spills that could hurt baby or mess up diaper bags).

In summary, third-party testing confirms MAM glass bottles are free from heavy metals like lead and meet high safety standards. They’re a solid choice for parents prioritizing a nontoxic feeding product. As one parent put it on Reddit, knowing MAM’s paint tested lead-free was a big factor in choosing them over other glass bottles.

It’s always good practice, of course, to inspect bottles periodically – with glass, run your finger over the markings to ensure none are chipping (they shouldn’t, but just in case). If a bottle does crack or chip, discontinue use (any cracked glass is a hazard). But assuming normal care, these bottles should last a long time safely. Some parents of multiple kids noted they reused their MAM glass bottles for second siblings and they still looked pristine.

Now that we’ve covered safety, how do MAM’s glass bottles stack up against other popular glass baby bottles on the market? Let’s do a quick comparison.

Comparison: MAM vs. Other Glass Baby Bottles

There are quite a few glass bottle options out there, each with its own features. Here’s how MAM’s glass bottles compare to some other well-known brands:

• Philips Avent Natural Glass Bottles: Avent’s Natural line is another parent-favorite wide-neck glass bottle. Like MAM, Avent Natural glass bottles are easy to clean and have a breast-like nipple (though Avent’s nipple is more traditionally round with petals to prevent collapse). Avent bottles have an integrated anti-colic vent in the nipple ring. Parents often praise Avent glass for its convenience and simplicity​.
• One difference: Avent’s nipple shape is different (some babies have a clear preference between MAM vs Avent nipples). Also, Avent glass bottles typically come in 4 oz and 8 oz sizes, slightly smaller than MAM’s 6 and 9. Both are durable glass; Avent’s caps are not measuring cups, whereas MAM’s is. Price-wise they are similar (Avent ~$10-12 each). Avent had a recall in the past for a painted logo issue (now resolved), whereas MAM has a clean record on that front. If your baby doesn’t like one, it’s worth trying the other, as these two are often considered the top contenders for wide-neck glass bottles.
• Dr. Brown’s Options+ Glass Bottles: Dr. Brown’s is famous for its internal vent tube system that very effectively reduces gas and colic. They offer glass versions in both narrow and wide-neck Options+ series. The main trade-off is complexity vs colic relief: Dr. Brown’s has multiple parts (bottle, vent tube, vent insert, etc.) that do add to cleaning time. Many parents start with Dr. Brown’s if their baby has reflux or colic, then switch to something like MAM once the baby’s digestive system matures a bit and they want an easier routine.
• Dr. Brown’s glass bottles are high quality and come in 4 oz and 8 oz sizes. MAM vs Dr. Brown’s: MAM wins on ease of use and cleaning (fewer parts, easier to assemble, no small crevices for milk to get trapped). Dr. Brown’s may win for a baby with severe colic due to its two-piece vent that eliminates almost all air bubbles. Some parents report MAM worked just as well for their baby’s gas, while others stick with Dr. Brown’s for that reason.
• Also, note that some older Dr. Brown’s glass bottles had issues with exterior paint (lead in paint markings) – the company has since addressed this, but many safety-conscious parents specifically chose MAM or Evenflo instead to avoid that concern​. If your baby doesn’t need the special vent, MAM is simpler and has that breast-like nipple advantage over Dr. Brown’s more standard nipple shape.
• Evenflo Glass Bottles: Evenflo makes classic, old-school glass bottles that are very affordable. They come in narrow neck (often sold in 4 and 8 oz 3-packs for a low price) and a newer Evenflo Balance+ wide-neck glass version designed for breastfed babies.
• The pros of Evenflo are price and basic functionality – glass is glass, so they’re just as safe and inert, and the narrow ones in particular have been around forever.
• The cons compared to MAM: Evenflo’s standard nipples are not as nipple-like (the Balance+ wide nipple is better, but the bottle shape on those is a bit odd and some parents report leakage issues with the wide version). The narrow Evenflo bottles also require a cap + disk to seal for travel (more pieces).
• For a budget, Evenflo is great; but many find MAM’s nipple and overall design superior for combining breast and bottle feeding. Evenflo’s markings, by the way, also tested lead-free in recent tests, so they’re a safe option​. Some parents actually use MAM nipples on Evenflo bottles or vice versa to get the best of both – but if you want one integrated product, MAM offers a more “premium” experience (with a cost to match).
• Lifefactory Glass Bottles: Lifefactory introduced glass bottles with silicone sleeves for protection, which became popular especially among eco-conscious parents.
• These bottles have a cool, colorful sleeve that helps prevent breakage if dropped and gives a good grip. They are also convertible to sippy cups later by changing the top, extending their use. Lifefactory bottles use a narrower nipple (not as wide or breast-shaped as MAM’s). They are quite heavy (the sleeve adds weight) and significantly more expensive (often $15-18 per bottle with sleeve). The sleeve can also obscure the measurement lines, which some parents find annoying (you often have to peek under or remove the sleeve to see markings).
• Compared to MAM, Lifefactory is all about durability and style, but babies may not prefer the nipple. MAM is likely a better feeding experience for baby; Lifefactory might win on drop protection. Both are very safe (lead-free, BPA-free, etc.). Some parents use both: Lifefactory for travel/daycare due to the sleeve, and MAM at home for ease of feeding.
• Chicco Duo Hybrid Bottle: A newer innovation, the Chicco Duo is a “hybrid” bottle with a glass inner layer and plastic outer layer fused together. This gives you the cleanliness of glass (milk only contacts glass) but the outer durability of plastic (less chance to break, and lighter weight). It’s a clever idea.
• The Chicco Duo’s nipple is more like a traditional round nipple (Chicco’s NaturalFit). Parents who have tried them say they like the concept, but some worry about the longevity of the fused layers (if dropped, does the inner glass break and stay contained? It hasn’t been out long enough to know). In any case, the Chicco Duo has gotten awards for innovation​. Versus MAM: Chicco’s advantage is shatter-resistance, MAM’s advantage is a proven nipple and simpler one-material construction. Also, the Duo is priced similar to MAM (a bit over $10 each).
• If you’re torn between glass and plastic, the Duo might be a compromise. But if you’re fine being careful, pure glass like MAM has fewer questions about materials (some ask, “what plastic is on the outside and could it wear down?” with Duo).
• Comotomo – (Note: Silicone, not Glass): Comotomo is not glass, but worth mentioning because many parents compare “alternative” bottles. Comotomo bottles are made of soft silicone. They’re known for a very breast-like shape and feel (the whole bottle is soft and squishy).
• They’re great in terms of being BPA-free and fairly easy to clean, but silicone can sometimes absorb odors and can wear out (and heavy metals have been found in some silicone products in trace amounts). They also only go up to 8oz and are pricey.
• Why mention them? Because some parents consider silicone as an alternative to glass for toxin-free feeding.
• MAM vs Comotomo: MAM’s nipple is flatter (some babies prefer that, some like Comotomo’s bulbous nipple). MAM’s glass is rigid (not squeezable), whereas Comotomo can be squeezed (mimicking let-down reflex). Both are good for breastfed babies generally. If you specifically want glass, Comotomo isn’t in that category; but if your main goal is avoiding plastic, both are valid routes (glass vs medical-grade silicone).
• Other Brands: There are other glass bottles like NUK, Tommee Tippee, Joovy Boob, Medela (their Calma nipple can be used on a glass bottle), Pura Kiki (stainless steel), Natursutten (glass bottle with natural rubber nipple) etc.
• Here’s a quick take: NUK Simply Natural glass – has an orthodontic angled nipple, but an older batch had issues with painted logos (so research current production if considering). Tommee Tippee Glass – Tommee Tippee did release a glass version of their wide “Closer to Nature” bottles; they have a very fast flow nipple and some parents had trouble with leakage, so they’re less common.
• Natursutten Glass – these are neat because they come with a natural latex rubber nipple (if you want all natural materials, no plastic or silicone at all). Downside: latex nipples wear out faster and some babies are allergic or just don’t like the rubber taste.
• Pura Kiki – not glass, but stainless steel bottles that can use various silicone nipples/tops. They’re virtually unbreakable and plastic-free, but you can’t see how much milk is inside easily (steel is opaque), which some parents find inconvenient. And they can be pricey.

In the landscape of options, MAM’s glass bottles hold their own as a top choice, especially for parents who value an excellent nipple design and hassle-free cleaning. They might not have as elaborate a venting system as Dr. Brown’s or the drop-proof sleeves of Lifefactory, but they strike a balance: simple, safe, and baby-friendly. BabyGearLab (a popular baby product review site) included the MAM glass bottle in a test and noted that the borosilicate glass is durable and the simple design makes it easy to use, fill, and clean, echoing much of what we’ve outlined.

To choose the best bottle for your baby, consider what matters most: If colic is your main worry, a Dr. Brown’s might be your starter (you can always switch to MAM later). If ease of use and breast/bottle switching is key, MAM is a frontrunner. If budget is tight, you might mix a couple of MAM bottles with cheaper backups. Many parents actually keep a few different bottles on hand and see which baby prefers – every little one is different!

Finally, let’s talk about the practical details of buying MAM glass bottles – how much do they cost, and where can you find them?

Pricing, Availability, and Where to Buy

Price: MAM Feel Good glass bottles are generally sold individually, and the price for a single bottle hovers around $12 to $15 (USD) for the 6 oz or 9 oz size in the U.S. market. For example, Target currently lists both the 6 oz and 9 oz single bottles at about $12.89 each​. A 3-pack “Gift Set” of 6 oz bottles is about $34.99 (which saves a couple dollars)​.

Prices can vary slightly depending on the retailer and any sales. In Europe or other regions, pricing might be different – for instance, in Malaysia one bottle is around RM33–58 (which is roughly $8-13 USD) depending on size​

Overall, MAM glass bottles are priced in the same ballpark as other premium bottles. They’re a bit more expensive than basic options (e.g., 3-pack of Evenflo for $9, or standard Avent plastic bottles), but comparable to Philips Avent glass and a bit cheaper than Lifefactory or Natursutten.

Availability: Availability has improved a lot recently:

• In the United States, the easiest place to find MAM glass bottles is at Target. Target carries them online and in some stores under the “MAM Feel Good Glass Bottle” product name. You can also buy directly from MAM’s official website or their Amazon storefront – just be cautious to buy from authorized sellers on Amazon to get legitimate products.
• Amazon does have MAM glass bottles, sometimes in different colors or bundles, but prices have ranged from reasonable to high. (At one point Amazon showed a single 260ml MAM glass bottle for $24, but with competition now, the price should normalize around $13-$15. Always check multiple listings or wait for restocks if the price seems inflated.)
• Walmart: MAM glass bottles have appeared on Walmart’s website via third-party sellers. For example, a listing might show a 9oz (260ml) MAM glass bottle for ~$28​, which likely indicates an import or third-party vendor (since that’s higher than retail). Walmart stores typically carry MAM pacifiers and sometimes MAM plastic bottles, but the glass ones may not be on shelves widely yet. If you prefer Walmart, online is your best bet, but compare the total cost with other retailers.
• BuyBuy BABY (in the past) and specialty baby stores have carried MAM products; with BuyBuy Baby’s recent store closures, that’s less of an option, though their website or successor might still stock some inventory.
• Other Online Retailers: Sites like Babylist or Nordstrom (for the set) have occasionally stocked MAM glass bottle sets. Also, some eco-focused baby shops and European import stores list them.
• International: In Europe, MAM bottles are quite common. You can find the glass ones in pharmacies, baby stores, and online on Amazon UK, EU, etc. In the UK, for example, retailers like Boots, John Lewis, and Amazon UK carry MAM glass bottles. (John Lewis has a starter set with bottles and a pacifier that’s popular, and it had strong reviews – 4.5/5 stars over 100+ reviews​) In Asia and the Middle East, you might find them through distributors or on regional e-commerce sites like Lazada or Shopee (MAM has official stores there). Australia also has MAM products via Baby Bunting and other stores.
• If you’re unsure where to buy in your country, checking MAM’s official website and using their store locator or contacting customer service can help. MAM’s site often has a “Where to Buy” section.

Best Places to Purchase (Tips): If you’re in the US, Target is arguably the best place to purchase right now – the pricing is fair, and if you have a registry completion discount or Target RedCard, you can save a bit more. Plus, easy returns if needed. Amazon is convenient for many; just watch for those price fluctuations. If you catch Amazon when it’s sold by MAM or Prime shipped at the normal price, it’s as good as any. For bulk buying, see if any retailer offers multi-packs – the 3-pack gift set we mentioned is one, and sometimes Amazon or others have a 2-pack.

Also, consider baby registry completion discounts – if you register at Target, Amazon, or Babylist, you could add the MAM bottles to your registry and then use your one-time discount (usually 10-15% off) to purchase them later, which saves a few dollars.

Lastly, MAM Club: MAM’s official site has a “MAM Club” where they sometimes send coupons or have special offers for members. It could be worth signing up to see if they offer any discounts on products.

One more thing: Always double-check you’re buying the glass version – MAM’s Easy Start (plastic anti-colic) bottles look somewhat similar in photos (same shape/cap style) and are often sold next to the glass ones. The glass line is usually labeled “Feel Good” or explicitly says glass. If shopping online, read the title and description to be sure. The weight is a giveaway too (glass bottles weigh ~0.5 lbs each​, whereas plastic are very light).

In summary, MAM glass bottles are moderately priced premium bottles that you can find through major retailers. The investment in a few of them can be well worth it for the benefits they provide, according to many parents.

---

Final Thoughts: If you’re a parent looking for a safe, effective, and thoughtfully designed glass baby bottle, MAM’s Feel Good glass bottles are definitely a contender for “best in class.” They carry the heritage of MAM’s baby care expertise, and they check a lot of boxes: from being free of toxins to being easy to use and widely loved by babies. Like any bottle, there’s a bit of trial and error to see if it’s the perfect fit for your little one, but the odds are in your favor with MAM given the high acceptance rates and positive reviews.

We hope this deep dive has given you a clear picture of what MAM glass bottles offer, how they compare to others, and what real users have experienced. Happy feeding – and here’s to finding the bottle that makes feeding time feel good for both baby and you! 🍼✨
