Description
The Philips Avent Natural glass baby bottle is designed for first-time and experienced parents who prefer premium borosilicate glass while combining breast and bottle feeding. The Natural Response nipple releases milk only when baby actively drinks, letting baby control the pace like breastfeeding; when baby pauses to swallow and breathe, no milk flows. Its wide, soft and flexible breast-shaped nipple supports a comfortable latch, while the no-drip design helps prevent spills and lost milk. An integrated anti-colic valve sends air away from baby's tummy to reduce colic and discomfort. Premium borosilicate glass is BPA-free, heat and thermal shock resistant, so the bottle can be stored in the fridge, warmed, washed and sterilized with confidence. The ergonomic shape is comfortable to hold, and a few parts plus a wide bottleneck simplify filling, assembly and cleaning. This 4oz bottle includes a slow flow nipple (Flow 2) and is designed for use with Philips Avent Natural Response bottle nipples. Five nipple flow rates are available; age is a guide, while baby's drinking approach and feeding cues help determine when to move up or down in flow. It is the 1 Pediatrician recommended natural baby bottle¹, giving parents reassuring material durability without giving up a natural feeding rhythm. ¹ IQVIA Health ProVoice Survey 2025, USA

These bottles feel very high quality and are easy to clean. I love that they’re glass instead of plastic, and they don’t hold smells or stains. The nipples have a natural feel that helped my baby switch between breastfeeding and bottles easily. They’re durable, easy to hold, and overall have worked really well for us. Definitely worth it if you’re looking for glass baby bottles!

We really liked these Philips Avent glass bottles. They feel very high quality, are easy to clean, and the glass gives extra peace of mind since it doesn’t retain odors or stains. The natural nipple helped a lot with combining breastfeeding and bottle feeding without many issues. Our baby really likes them, and my wife also loves how practical and convenient they are to use every day. The flow seems comfortable for the baby, and we’ve had almost no leaks. Highly recommended for parents looking for a cleaner and more durable option.

The baby is officially 3 weeks old and exclusively bottle fed. I go through so many of these in a day and I hope my review is helpful. This is baby#3 and with the older 2 I used the avent plastic bottles so I'm coming with a lot of experience. My only regret is that I wish I had bought these for them as well. I don't know how to explain it, but these just clean better and quicker. We used the #2 nipple right when she was born and we did not experience any leaks and she also burps easily. Now I know every child is different but I'm so happy that this is working for her. Its such a struggle for parents to find the right match for their baby and I totally understand how frustrating it can get. The quality on these is excellent, they have been performing really well! I have noticed they have improved the nipple structure slightly, my last baby was 5 years ago and he had to go through a bit of a learning curve due to leakage but this time around we are so happy! This happy mama has a fed baby!

These glass bottles are just the right size for my new baby grandson, less air to go in his tummy, great flow on the nipple size that it came with, I just forgot to order the bottle sleeves to go onto the bottles , you definitely need them so they don't break if you drop them and you won't burn your hand holding them. You can't go wrong with Phillips Avent baby bottles, little pricey but worth it!

I love the glass. Feels very clean. Sometimes they break but I still think they’re worth it and they do sell silicone covers if you are accident prone

I really liked this baby bottle. The glass feels very high quality, thick, and durable, which gives me more confidence compared to plastic bottles. It also looks clean and simple, with a beautiful and classic design. The Natural Response nipple works well and feels very natural for feeding. I like that it helps control the flow, so my baby can feed more comfortably without spilling or getting too much milk at once. Cleaning is also very easy since it’s glass and doesn’t hold odors or stains. It feels very hygienic, which is very important for baby products. The size (8oz) is perfect for everyday use, and the overall design is well thought out. It feels like a premium product in every detail. Overall, I’m very happy with this bottle. It’s safe, practical, beautiful, and high quality.

Update 3: I had to come here and write another review about almost a year later because there’s been some minor issues with these bottles but we still love them and would choose them over the other available bottles due to less toxicity. The issues we’ve encountered is that the caps fit strangely tight on some of those bottles and that can cause leakage sometimes. And this for some reason happens with new bottles and not old ones so far for us, so it’s not due to use overtime for sure. Another thing is, sometimes the bottles may arrive cracked and sometimes look like it’s cracked but it’s not so it’s always important to inspect before use right after opening them. I contacted Amazon for mine and I was refunded. Other than that, we’ve ordered these bottles 2-3 times since and still are using them. Update: I love these bottles and I’ve dropped them a few times or bumped them and they are just fine. I would a few small cracks here and there but it’s on the outside and not the inside and they are super small. Only thing is, the cap will sometimes unscrew and from my observation is due to temperature change. So just make sure to the cap completely off then screw it back on after heating the bottle before shaking it. Then no problem! I’ve done my research before I picked this bottle. Other reviews have shown that these might crack or break easily but I wanted to test that out myself. So far, there’s only been slivers of cracks on 1 out of 4 bottles that come in the box set. And that is highly likely due to the fact that I’ve dropped it multiple times while washing them because the soapy water is slippery. But there was one crack that I didn’t notice before that was there that I don’t think was caused by my error. So I’m unsure about that. As far as sterilizing them, they have no problems fitting or being sterilized in Papablic sterilizer (which I highly recommend; has much more room, simple to use, and less pricy than other sterilizers). They haven’t had an issue of being sterilized and dried and then crack due to temperature change. I just run the cycles and leave them in there until theyre done and they come out just fine. I chose this bottle because glass is always better than plastic, no matter if the product says BPA free. Plastic does affect human body hormones and reproductive system at times and with usuals and time I’m not willing to take the risk with plastic when my kid is this young. The other reason I chose this bottle is because of its nipple-shaped that actually resembles bipple and requires the baby to suck rather than letting it flow free into their mouth, which can then cause nipple confusion because it makes them think they don’t have to work for the milk. And the material of the nipple on the bottle is just a more soft and flexible than let’s say Dr. Browns which seems so hard and not fitting for their mouth to suck on. I mean really think about it, if you have to suck 24/7 all the time, wouldn’t you rather use something comfortable? Only issue I have had with this is 1 out of 4 bottles from the box had a strange dripping issue from the little hole in the side of the nipple. My husband noticed that while feeding our kid so just watch for that. And the cap for the bottle can be hard to get used to at first but they require you to squeeze then take off. They can be very snug at first so beware as you use them more often it’ll come off easier and you’ll get the hang of it. I’m planning to get flow 3 once my kid hit 3 months old or drinks faster from let down, whichever comes sooner. But I urge you to read this review thoroughly so you can hopefully buy the best bottle for your child. Overall the benefits outweighs the tiny inconveniences so definitely recommend!
