Glass vs. Plastic Baby Bottles: What Do Reddit Parents Actually Use?
Reddit parents weigh in on glass vs. plastic baby bottles — the microplastics debate, daycare restrictions, and what most families actually end up doing.
If you've spent any time in parenting subreddits, you've seen the question come up over and over: should I use glass or plastic baby bottles? The microplastics research has made a lot of parents reconsider plastic, but glass comes with its own trade-offs — weight, breakability, daycare bans, and cost.
I read through hundreds of comments across r/BabyBumps, r/ScienceBasedParenting, r/NewParents, r/beyondthebump, and r/moderatelygranolamoms to find out what parents actually choose after living with both.
The Case for Glass
The overwhelming reason parents switch to glass is microplastics. A widely-cited 2020 study found that plastic baby bottles release millions of microplastic particles when heated — and that number jumps dramatically with sterilization. But beyond the health angle, parents who use glass consistently mention three practical advantages: they clean better, they last longer, and they don't get that funky milk smell plastic bottles develop over time.
100% yes. Glass cleans better, sanitizes better, lasts longer, doesn't degrade, and won't leech microplastics over time in to the milk/formula. I've noticed the difference especially between the medela plastic bottles I have to use for my breast pump (no choice there) that have degraded and become discoloured over time compared to our Dr. Brown's glass bottles that still look brand new to this day, after 8+ months of continued use and countless runs through our dishwasher!
I would not heat plastic. We use strictly glass & silicone, only heating glass. We thaw in fridge. We have found the investment in glass to be well worth it-we keep a smaller inventory and their durability really matters bc they get washed every day. We store in metal water bottles, silicone bags (haakaa) or glass jars/carafe for bulk storage & then pour into the bottles before use. We already know plastic leaches endocrine disruptors, etc, and infancy is a really sensitive period. If cost is ...
One parent with a PhD in the health effects of chemical exposures during pregnancy offered this balanced take:
My PhD dissertation was on the long-term health effects of exposures to chemicals in plastics during pregnancy and breastfeeding. High exposures to these chemicals can increase risk of adverse metabolic, hormonal, and neurological health effects across the life course. This doesn't mean that if you use plastic bottles, your baby will definitely experience any of these issues. It just means there's a higher risk. I plan to use silicone for bottles, as well as for milk storage and would highly rec...
The Case for Plastic
Plenty of parents stick with plastic — and they have good reasons. Plastic bottles are lighter, cheaper, unbreakable, and accepted everywhere including daycare. Several parents also pointed out that microplastics are already unavoidable in water, soil, breastmilk, and formula — so eliminating one source may not move the needle much.
All the food she/he is going to eat in the future is full of microplastics. Bottless are a trivial concern imo
Plastic bottles and then hand wash to minimalize microplastics. I was scared I would break glass bottles if I travel with them, it also adds weight in the diaper bag. I'm also clumsy and drop stuff a lot so didn't want to risk it. Glass also doesn't cool as fast so I didn't want to risk my son burning his hands if he put his hands on it. Never regretted plastic. Especially by the time my son could hold his own bottle. I didn't have to worry about him dropping and breaking it.
What Most Parents Actually Do: The "Both" Strategy
The most common recommendation is to use both. Glass at home where you control the environment, plastic or silicone for daycare and travel. This came up so often it's clearly the consensus approach.
I would recommend both. Glass for use every day, and plastic for travel.
We have both glass and plastic avent bottles. Definitely like the choice. Plastic for daycare and going out and glass for home. The plastic bottles are only good for 6 months according to avent so we had to replace them. It's more cost effective to have mostly glass IMO. My 9 month old doesn't hold her own bottles so the heaviness hasn't been an issue yet.
Best Glass Baby Bottles According to Reddit
Philips Avent Glass
The most recommended glass bottle across all the threads we analyzed. Parents love Philips Avent glass for its durability — multiple commenters report dropping them on hardwood, concrete, and even down stairs without breaking. They're widely available, dishwasher safe, and come in both the Natural and Natural Response nipple styles.
Philips Avent Glass
The most popular glass baby bottle on Reddit. Parents praise its surprising durability, easy cleaning, and wide availability. Works with Avent Natural Response nipples.
OTOH I have dropped a (Philips Avent) glass bottle down a flight of stairs without it getting a single dent/shattering so YMMV.
We use Philips avent glass bottles and just last night it fell off a table onto tile and didn't break. It was quite loud so I think they're strong.
Dr. Brown's Glass
The go-to choice for babies with gas or colic issues, thanks to their internal vent system. Parents consistently say the glass version cleans better and lasts longer than the plastic Dr. Brown's. The main complaints: the anti-colic vent creates extra parts to wash, and they can shatter if dropped on tile (though hardwood drops seem fine).
Dr. Brown's Glass
Best glass bottle for gassy babies. The internal vent system reduces colic and air intake. Extra parts to clean, but parents say it's worth it for fussy babies.
Bought and currently using Dr. Browns glass bottles (narrow). Yes they are heavy, yes we have to be mindful of them falling/getting chipped, but I much prefer them then plastic bottles. They get properly clean and don't fade or smell from constant washing. We used plastic for our first born and I hated how they faded and started to smell after a while.
I used plastic with my first and glass with my second and tbh I prefer the glass. We switched because we were concerned about PFAS and microplastics, but honestly I like the feel of them better. We use Dr browns glass with a silicone sleeve.
Evenflo Balance+ Glass
A favorite among lactation consultants for its nipple shape that mimics breastfeeding. Parents appreciate that the glass version has no paint markings (eliminating the lead paint concern that plagues some other brands). At 6oz, it's a practical middle size.
Evenflo Balance+ Glass
Top pick by lactation consultants for breastfed babies. No paint on glass (no lead concern), affordable, and available in a practical 6oz size.
I'm using glass because micro plastics and pfas freak me out, plus I don't think it's any harder to use glass. I use the Evenflo glass bottles. They don't have any paint on them so there's not really any chance of them having lead in the paint as has been reported with some bottles (not sure if that's true but I wanted to be cautious). They hold over 8 ounces. I use the standard neck balance nipples with them because they are supposed to be better for breastfeeding than the ones that come with t...
We use glass bottles for baby and really like them (Evenflo balance+) and find peace of mind since those are the only thing ever being heated in our routine- I pump with plastic pieces but pumped milk is immediately put into a glass jar in the fridge to chill, poured up into our glass bottles, and then warmed. Any freezer milk does go into plastic bags because I simply don't have the time/space to use glass for that, but the baggies are thawed in the fridge and never heated. I also feel more com...
Chicco Duo
The "best of both worlds" hybrid: a thin glass inner lining surrounded by a plastic outer shell. It looks and feels like a plastic bottle but keeps milk away from plastic entirely. Compatible with Lansinoh and Pigeon nipples. Popular with parents who want glass safety without the weight or breakability concerns.
Chicco Duo
Glass-lined hybrid bottle that feels like plastic. Lightweight and durable with a glass interior that keeps milk plastic-free. Compatible with Lansinoh and Pigeon nipples.
We bought the chicco duo bottles! Very thin glass on the inside, but plastic outside. They look and feel like plastic. The pigeon and lansinoh nipples fit in them too which is great because those are highly recommended by IBCLCs.
Also love the Chicco Duos, they're our primary bottle. They feel super light like plastic, the inner glass lining is ideal.
Comotomo (Silicone Alternative)
Not glass, but the most-mentioned "third option" for parents who want to avoid both plastic chemicals and glass breakability. Made entirely of silicone with only a small plastic ring connector. Soft, squishy, and extremely easy to clean — no bottle brush needed. Popular for daycare since many centers ban glass but accept silicone.
Comotomo
The silicone middle ground between glass and plastic. Soft, squishy, easy to clean without a brush. Accepted at daycares that ban glass. Great for babies who resist traditional bottles.
Take a look at comotomo, it's what we used for bottles (can be found at Target). Silicone bottle, silicone nipple. There are two plastic pieces (the ring that connects the nipple to the bottle and the lid) and neither comes into contact with the milk while it's being heated.
Lifefactory
A glass bottle with a built-in silicone sleeve that protects against drops and gives a better grip. Parents love that it converts to a sippy cup with a different lid as baby grows. Expensive (~$15/bottle) but extremely durable and lasts through multiple children.
Lifefactory
Premium glass bottle with built-in silicone sleeve for drop protection. Converts to sippy cup with different lids. Expensive but lasts through multiple kids.
I LOVE my LifeFactory glass bottles! I had to convince myself to buy them since they're "so expensive". But so easy! Attractive, healthy, clean, no weird middle parts with strange edges and designs - straightforward except don't overtighten the nipples, the anti-gas patent involves keeping the lid a little lose. You'll get the hang of that easy but others will overtighten often. It doesn't leak. Totally recommend. We also love Comotomo for the newborn stage. Mine took to Comotomo nipples a littl...
The Lead Paint Problem
One thing that caught us off guard in the research: some glass baby bottles have painted measurement markings or logos that contain lead. This has led to recalls and is flagged repeatedly by parents in r/moderatelygranolamoms and r/ScienceBasedParenting. The solution is straightforward — choose bottles without painted markings (Evenflo Balance+ and Lifefactory are commonly cited as paint-free options) or check the Lead Safe Mama database before buying.
Yeah, lots of issues with plastic bottles. BPA free still leeches other things, see: https://pmc.ncbi.nlm.nih.gov/articles/PMC9441614/ like phthalates and other BPF BPS (similar to BPA). Microplastics you already know about. Think about minimizing polyester, fleece, in baby items as well. Rayon and bamboo I'm not too sure about. I know the processing of these into textiles is intensely bad for the environment. Cotton and wool are good choices. With glass, something to be aware of is that f...
The Daycare Problem
This is the single biggest practical barrier to going all-glass. Many daycares flat-out ban glass bottles due to breakage liability, and parents in every thread we read confirmed this. If your baby will be in daycare, you have a few options:
- Use silicone for daycare — Comotomo and similar silicone bottles are accepted everywhere
- Try the Chicco Duo — it looks/feels like plastic so some daycares accept it
- Accept the dual system — glass at home, plastic at daycare
- Ask before buying — check your daycare's policy before committing to an all-glass set
Honestly, find a different bottle. Telling the teachers "hey I've chosen to use this container that is hazardous to both my child and other children if dropped, and even though my baby could feed himself, please make either him or another baby scream in hunger unnecessarily." The teacher's "convenience" is not having to listen to baby cry because it's hungry (or tired or needs changing etc.) and they don't have enough hands to help everyone at once. If you want everything 100% your way, get a ...
The Bottom Line
If you can afford it and aren't sending bottles to daycare, glass is worth trying. The cleaning advantage alone makes many parents prefer it. The most practical approach is glass at home, something else for daycare, and not losing sleep over it either way.
It's all stressful but try not to get too eaten away by it all. Most people used to use glass bottles, their babies were fine. Most people now use plastic bottles, their babies are fine. Just look street the bottles, clean them carefully and use established sterilising techniques so you're not degrading the materials, and change the teats fairly regularly. I used plastic to start and switched to glass only because it was easier for me to control the temperature when we were doing formula (four...
