Thread: "Am I the only loser who is still using plastic bottles? "
I recently discovered the Chicco Duo bottles which are plastic outside but coated with a thin layer of glass on the inside so it’s still light and durable. Have been my go-to for daycare and bottles are going strong for over half a year of daily use, we boil to sanitize and put them through the dishwasher.
Thread: "Am I the only loser who is still using plastic bottles? "
My little one used those exact ones her entire infancy, I looooved them and was glad she did too.
Thread: "Am I the only loser who is still using plastic bottles? "
Yes! We used them with #1 and will use again with #2. It doesn’t solve the whole plastic problem bc I do pump into plastic and obv have to store and freeze in plastic bags, but at least the milk isn’t being heated while in contact with plastic also being heated. Not sure if it does make much difference but it was at least a little reassurance
Thread: "Glass vs Plastic Bottles?"
* I'm a total klutz, our floors are hardwood and tile, and our countertops are that awful ultrahard quartz that destroys anything with the tiniest bump. Our glass bottles (Phillips Avent) made it through baby number one just fine and are on deck for baby number two in a few months. If you're really nervous, you can get [silicone sleeves](https://www.google.com/search?q=silicone+sleeve+for+glass+baby+bottle&sca_esv=b6ab7d9e5410acba&rlz=1C1GCEA_enUS1096US1096&ei=0aPcZeOuCPL9ptQPxe2h8AM&oq=silicone+sleeve+for+glass++bottle&gs_lp=Egxnd3Mtd2l6LXNlcnAiIXNpbGljb25lIHNsZWV2ZSBmb3IgZ2xhc3MgIGJvdHRsZSoCCAEyChAAGIAEGIoFGEMyBhAAGAcYHjIGEAAYBxgeMgYQABgHGB4yBhAAGAgYHjIGEAAYCBgeMgYQABgIGB4yBhAAGAgYHjILEAAYgAQYigUYhgMyCxAAGIAEGIoFGIYDSOsRUOICWIIIcAJ4AZABAJgBYKABtAGqAQEyuAEDyAEA-AEBmAIEoALDAcICChAAGEcY1gQYsAPCAggQABgIGAcYHpgDAIgGAZAGCJIHATQ&sclient=gws-wiz-serp) or go for [Chicco Duo](https://www.chiccousa.com/duo-bottle/), which has a plastic outer for lightness and durability and a glass inner lining to protect against microplastics contamination. * Of course glass can go in the dishwasher; you use it for your water glasses, don't you? It's actually far more dishwasher-safe than plastic. * Bottle nipples are silicone and sometimes latex rubber.
Thread: "Which bottles are we using? "
Chicco Duo. They are plastic outside with thin layer of glass inside. Very lightweight. Easy for baby to hold when they become interested in that. We’ve dropped them a bunch on all sorts of surfaces and have had no breakage. I’ve read that MAM nipples fit them as well (but I’ve never tried as my daughter took the Chicco nipples just fine).
Thread: "What glass baby bottles do you use?"
Chicco duo, they're plastic outside and a thin layer of glass inside. Baby likes them just fine, and they're compatible with my spectra pump, same size as mam and avent bottles which I also have a couple of so I can swap out nipples. My baby will take pretty much any nipple thankfully.
Thread: "glass baby bottles vs plastic or silicone?"
I like the Chicco duo bottle. Plastic on the outside, but glass on the inside. You can use the nipple it comes with, but if baby doesn’t take to it, the lansinoh/pigeon nipples fit according to this tiktok https://www.tiktok.com/t/ZT8CqeYXk/ I’ve also used these bottles with the nuk standard neck nipples and they fit without any issues. My daughter also liked OLABABY bottles. I liked them more than Comotomo bc of the off centered nipples, which my daughter latched to better. I wouldn’t recommend trying to warm up the milk in the bottle though since silicone is so thick you won’t have much luck, learned that the hard way lol.
Thread: "Am I the only loser who is still using plastic bottles? "
I loved these bottles. Def recommend!
Thread: "Baby bottles glass vs plastic"
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.
Thread: "Philips avent and evenflo balance "
I found this comparison chart: [https://www.facebook.com/LactationHub/posts/waitbefore-you-throw-out-that-bottles-with-a-nipple-shape-or-flow-that-isnt-an-o/722051443028844/](https://www.facebook.com/LactationHub/posts/waitbefore-you-throw-out-that-bottles-with-a-nipple-shape-or-flow-that-isnt-an-o/722051443028844/) I used the Pigeon and Lansinoh nipples interchangeably on Chicco Duo bottles and the Avent glass bottles. That chart says that the Evenflow nipples fit the Chicco Duos, so I'd say there's a decent chance that they'll fit the Phillips Avent too. Maybe buy a small pack and test first though, unless someone else can confirm for sure? I did think the collar opening on the Avent bottles was a bit wider than the collar opening on the Chicco Duos, so you need to be paying a little more attention when you put the nipple in; if you don't get it centered when you screw the collar down, it can leak. It's also possible to pull the nipple out completely when the collar is screwed down, so just watch out for that if your baby likes to chomp the nipple and pull.
Thread: "Glass baby bottles"
We use the Chicco duo. Glass on the inside and plastic on the outside. Very durable. I did a drop test on one and dropped it from about 5ft on the hardwoods.
Thread: "PSA to those who use Phillips Avent Natural Response bottles/nipples!!"
Are you sure your talking about out the natural response nipples? The natural response nipples don't have a notch in the white ring so I'm not sure what you mean (you seem to be scribing a ring like what Chico duo use. Most bottle rings with a notch don't need to be lined up with the nipple air vent because the underside of the ring is recessed so the notch lets air into a channel under the hard plastic that goes 360 degrees around so the nipple orientation doesn't matter. What I did discover matters if the nipple has an airlock design like the Chico duo ones (the exposed little nub) is that the nub can fill with water during cleaning and essentially vapor lock the air valve on the lower flow nipples. To fix this, pinch the top and bottom of the nub between paper towels to pull the water out of it and it will work fine regardless of where the nub is in relation to the notch on the plastic ring.
Thread: "Which baby bottles did u love?? "
Chicco Duo was a great option for us. It’s lighter weight than standard glass bottles, which is nice for pumping. Our daycare also does not allow regular glass bottles or other glass containers, but they do allow the Chicco Duo bottles.
Thread: "Looking for 100% glass bottle suggestion?"
The Chicco Duo bottles are glass on the inside and plastic on the outside, so they won't break when dropped, but the milk only touches glass. https://www.chiccousa.com/duo-bottle/
Thread: "Glass baby bottles"
Yes this is what we use too and the pigeon nipples fit
Thread: "glass baby bottles vs plastic or silicone?"
I did glass - I have three kinds: Dr. Browns, Pigeon, and Chicco Duo which is glass inside plastic outside. I use the Lansinoh/Pigeon nipples for the latter. My baby isn't picky and is happy with any milk-delivering device, whether it is boob or bottle or cup. But my husband prefers the Dr. Brown bottle, I prefer the Pigeon, and we both like the Chicco Duo for on the go.
Thread: "thoughts on nanobébé bottles?"
Our baby enjoys Chicco Duo bottles.
Thread: "Which bottles are we using? "
pigeon and lansinoh nipples fit in these as well! Also a good option for mamas who want glass but do daycare.
Thread: "glass baby bottles vs plastic or silicone?"
I can confirm that the lansinoh and pigeon nipples fit this! We had some daycare restrictions but those were the only nipples my picky boy would use. It was a lifesaver. The nice thing is that the bottles were also super light so self feeding was easier.
Thread: "Glass baby bottles"
These are what we use and love them. Unfortunately, they are unavailable at the moment. I believe there is a supply issue.
Thread: "thoughts on nanobébé bottles?"
Mine would not take the Nano Bebe bottles. Or the Como Tomo. He sorta kinda takes the Nuk naturals but the one he really prefers is the Chicco duo. Honestly, if you can afford it, get a couple of different kinds (but just get one of each) and see what baby likes. Then buy more of that kind. Also make sure to use the slow flow nipple of whatever bottle you get. They're supposed to have to work for it just the way they would at the breast.
Thread: "Which baby bottles did u love?? "
Chicco duo have held up great and were the only bottle my baby really took too. Started with the number 1 nipple (slowest) and switched to 2 at 3.5 months, 3 at 6ish months and kept with it til now (1 year old). Glass inside plastic outside lightweight and accepted at our daycare which doesn’t accept any glass containers.
Thread: "glass baby bottles vs plastic or silicone?"
Babylist has a glass baby bottle sampler box! comes with a Dr Browns narrow neck, Chicco duo, Bibs, and Lansinoh bottle. https://www.babylist.com/gp/-/38514/1501940 i got this box and a Dr Browns wide neck bottle to try. we've tried all of them and my baby (EBF, nurses 99% of the time) doesn't seem to have a preference!
Thread: "Dr. browns and Philips bottles "
I didn't tell them because I was afraid of the same thing and no one has said anything so far. You truly can't tell at all that they have glass in them. I keep trying to find more info on a third party verifying that the Invinci-glass they use is truly glass and can't find anything. I really hope we don't find out later that they have lead or microplastics.
Thread: "Comotomo or Boon Nursh bottles?"
Have you looked into Chicco duo? They’re plastic but the inner lining of the bottle is a very thin layer of glass.
Thread: "glass baby bottles vs plastic or silicone?"
Seconding this! My daycare won’t do glass bottles so these were perfect. My daughter conveniently only accepted this brand for pacifiers and bottles.
Thread: "Bottle recommendations? NOT Dr Browns Anti Colic"
We love the Chicco Duo bottles with the Lansinoh nipples! My son alternates between breast and bottle now without issues. Dr Browns leaked for us, como tomo felt like it was pushing up against his nose. Chicco Duo is light and it’s lined with glass on the inside so milk isn’t touching plastic.
Thread: "Glass baby bottles"
I also use chicco duo. Super durable, haven't broken one and are on kiddo #2. Love that the measurements are laser etched so no peeling/fading paint etc
Thread: "What bottle does your mostly nursed baby take well?"
My 5 mo also loves the Chicco Duos - had to switch from Philips Avent bc daycare doesn't allow glass, so we are sort of tricking them with the glass inside the Duos. Baby hated the nipples they came with though. We use Pigeon nipples which I saw recommended on this sub for BF babies.
Thread: "What bottle does your mostly nursed baby take well?"
We have used Dr. Brown premie nipple, MAM 0 nipple, and Como Tomo slow flow. Finally settled on Chicco Duo, because we like that it’s less parts, glass inside the bottle, and slow flow nipple.
Thread: "Bottle dilemma"
Thank you! I should have mentioned that this would be our primary preference, but we can’t find Chicco Duo in stock anywhere! 😭
Thread: "What is your experience with glass baby bottles?"
I agree! Used these with my second and loved them!!
Thread: "Glass baby bottles"
We use the chicco duo bottles. Glass inside layer, plastic outside. Love them!
Thread: "Never buy glass baby bottles"
Chicco Duo bottles are the way to go! They’re thin glass with plastic on the outside. Sorry that happened to you 😞
Thread: "glass bottle recommendations"
We used the Chicco Duo bottles and really liked them. They're glass on the inside and plastic outside so very light weight and don't break when dropped
Thread: "Bottle dilemma"
Oh dang that’s such a bummer! We snagged some back in September without really understanding how useful they would be. Fingers crossed they come back in stock soon. Agree with everyone else here that the plastic pigeon ones are probably totally fine ✨
Thread: "Best baby bottle poll"
Chicco Duo weren’t on the list but they’re our preferred. Glass on the inside, plastic on the outside so they’re very lightweight but still only glass touching the formula. Boon Nursh have also been good. They’re able to convert to sippy cups too so that’s a bonus.
Thread: "What baby bottles are you all using? And glass or plastic?"
I use them. Love the bottle and that they're glass inside. Super light weight, don't worry about dropping them, but I hated the nipple. It was really hard for LO to drink from. We switched the nipple to lansinoh.
Thread: "Which baby bottles did u love?? "
Since my babies all went to daycare we couldn’t do glass so we did the chicco duo for my last baby (it’s glass inside and plastic outside)
Thread: "Best baby bottle poll"
I will scream lansinoh until I'm blue in the face. My baby had so many feeding issues, killing my BFing dreams. Lansinoh are the only bottles he gets a good latch on and doesn't click and choke. I use the lansinoh nipples on the Chicco duo bottles too
Thread: "What brand baby bottle worked best for you?"
Chicco Duo if you prefer glass cause it’s glass inside and plastic on the outside. Otherwise MAM have worked amazing for our daughter reflux plus it was an easy microwave sterilize option with its own parts
Thread: "comotomo bottles OR philips avent glass bottles!?! 🤨"
My personal preference is Chicco Duo (lined with glass on the inside and very lightweight) paired with pigeon nipples.
Thread: "thoughts on nanobébé bottles?"
Same! Baby did not take to nanobebe at all, but at 9 months, the duos are all we use
Thread: "Compatible Baby Bottle Cap Rings and Nipples"
apparently the chicco duo is compatible with the pigeon nipple for those looking for a deep latch
Thread: "Baby bottles glass vs plastic"
Same and my baby loves these bottles.
