I really love the glass bottle itself but the nipples for these bottles are horrible. It keeps collapsing with my baby while feeding. I like the plastic bottle nipples better since it doesn't collapse every time baby feeds

Great for Newborns
These Nuk glass bottles have been far superior then other popular brands of glass bottles we have tried (and we have tried a lot). They actually vent well without additional contraptions, they have multiple nipple options to help control the flow, and they wash well in the bottle washer. We only wish they made a larger size in the glass bottles in the US.

Nuk for the win
Small size with easy cleaning maintenance and no spillage! Comfort for the baby with every bottle with minimal weight to the actual bottle! Well worth it!

These NUK glass bottles are fantastic!
These NUK glass bottles are fantastic! They feel very sturdy and safe. The nipple design makes them easy for the baby to hold, and cleaning is a breeze. They also heat up quickly and evenly. They worked effectively for our baby with her reflux issues. This is definitely a product I enjoy using every day.

A durable, easy-to-handle glass bottle with a soft
The NUK Simply Natural Glass Bottle feels high quality and well made, with a sturdy glass material that is easy to clean and does not retain odors. The nipple is soft and comfortable, closely mimicking a natural latch, which helps with smooth feeding. The bottle is easy to hold and handle, and it feels durable enough for daily use. Overall, it offers great value with safe materials, thoughtful design, and reliable performance for both babies and parents.

Great bottles
We've introduced bottles to our almost 1-month old and they are splendid. They don't fit the Spectra pump we use but that's no problem. We save milk in silicone bags and pour off a meal's worth each time. The bottle goes into a Phillips warmer and gets nice and warm.

No just no
I was so excited to use these bottles because I used nuk bottles with my son. However, using these with my daughter was terrible. Although they are very durable, the air comes out while the baby sucks on the bottle nipple and the nipple will collapse and I had to unscrew the cap and put it back on for the nipple to come back up.

Perfect bottles for breastfed baby
My son loves these bottles. He is breastfed so it’s hard to find a bottle he actually likes. This is the closest one I’ve found to a breast. They’re leak proof and I like that they’re glass. They don’t break easy so it’s super safe. Also very easy to clean. The convenience of these bottles are perfect. So worth the money and will definitely continue buying. I’d also recommend these bottles to anyone breastfeeding especially.

Perfect for the working and nursing mom
My baby loved these bottles when changing between nursing and bottle feeding when I returned to work. I knew the safety of glass over plastic and felt safe knowing how durable and clean these bottles were!

Glass bottles 🙌
I have been using these for my twins for their first year! I got the 4oz & the 8oz. They are wonderful! Glass is great because you never have to worry about micro plastic & they wash amazing in the dishwasher! Highly recommend!!!

Love the glass and slow flow nipple
These bottles were my babies fav! We love that it’s glass and slow flow. Literally so easy to clean and didn’t leak once! The nipple is shaped for breastfeeding babies.

worst bottles ever
Baby choked on them a lot. Lots of spit up after switching to these. way too fast flow. Also, a hole in the nipple on the edge leaks if not held up which is a terrible design that yields no benefit.

Bring them back!
The only bottle baby will take and are unfortunately becoming sold out everywhere with what looks like no expectations of restocking. I never write reviews so this comes from the heart, lol.

We love the Nuk glass bottles. Our baby goes back and forth from nipple to bottle with no confusion.

Beautiful glass
I only use glass or silicone baby bottles. These are amazing but my baby didn't love the nipples. I wish he did! I found a coozi that fits it but he spit milk out while sucking. They bottles clean so well in my dishwasher. I use a tommee tippee disc that fits perfectly and use these to store homemade baby food or other things.

The only bottles we use
I am a big fan of glass bottles in lieu of plastic, so we opted for these with our son and love them! Never had one break or shatter, they are very resilient and surprisingly lightweight

I loved these bottles!!
These were my favorite bottles when my son was a newborn! Perfect size for when he wasn’t drinking more than 4 oz. I love that they are made of glass which is more natural than the plastic bottles. These were very easy for my son to drink from. They are obviously heavier than plastic bottles being they are glass for my that didn’t matter. I highly recommend these bottles to any mom of a newborn!

Great glass option. Baby loved this nipple. The only thing I don’t like is that there’s no sippy attachment top.

Best ever
[This review was collected as part of a promotion.] My son is now exclusively breastfed and every once in a while I do have to use a bottle when hes with his grandparents and it's the only bottle my son will take. And I'm so glad that they have them because for my next baby I am just going to keep my glass bottles and just buy new nipples so these nipples so more environmentally friendly and reusable and I completely love it
