Review: An Absolute Life Changing Bottle - I am not someone who usually writes reviews, but I am genuinely so impressed with this bottle. I honestly did not want it to be any good because of the price. I knew if it made a difference, this was the solution, and it would be an expensive one. I am a single mom supporting both me and my baby, I don't make purchases lightly as I am on an extremely tight budget. Both fortunately and unfortunately, it was exactly what I was looking for and worth every penny. After buying the one, I went in and bought 3 more. We have an entire cabinet full of bottles, Dr. Browns, Parents Choice, Boon Nursh, Tommy Tippee. We probably have 20 bottles in our cabinet of all different brands. Since purchasing this bottle, it is the ONLY bottles we use. I am constantly washing and rotating just these 3 bottles. That's how much of a difference it made in our lives (and shows how easy they are to wash, only 3 parts!) I bought this bottle in desperation at 3:00 AM while trying to calm my refluxy 5 week old. He is combo fed. I both nurse and introduced bottles at 3 weeks of age. The bottles we were using before were a nightmare. Too many parts, nipple confusion, a weak latch, and worst of all, the flow was way too fast. They did not allow him to pause and take breaks naturally like he does when nursing, if he stopped sucking he was flooded with milk. Even when I stopped him to burp, it felt like he was being overwhelmed with milk. His reflux was awful and feeding was stressful for both of us. I bought this bottle as a last ditch attempt to make something work. I thought bottles just weren't going to work for us, but I am a single mom and was returning to work soon. I had to do something. Like I said, part of me honestly did not want it to make a difference because then I knew I would have to buy more. But it arrived, I used it, and it immediately helped. He latched onto it deeply, just like he does at the breast. The milk comes out of five tiny holes in the nipple, similar to a real breast, and no milk flows unless he is actively nursing. He can feed from the bottle the same way he nurses, without having to suck aggressively like with other bottles. The nipple is genuinely very soft and does feel almost like skin. It's weird, but it makes a difference. Within almost a day, this one bottle fixed our feeding issues. He can stop and take breaks without being overwhelmed by milk. Babies naturally nurse in a rhythm of suckle, suckle, breathe, repeat, and this bottle actually allows that. His latch is deeper and stronger, and the feeding feels much more natural. For someone who nurses and also uses bottles, this has been a total lifesaver. On top of that, the bottle itself is incredibly sturdy. I was nervous about the glass, but I have dropped it more than once and it has not broken. It only has three parts to wash, which makes a huge difference when you are exhausted. The design is simple, well thought out, and takes so much of the frustration out of bottle feeding. If money wasn't an issue, I would buy 10 more. All babies are different and do have different needs and preferences, but honestly if you are having feeding problems with the bottle but not the breast, I would recommend this bottle a thousand times.
Review: Best bottle out there but cheap company - My absolute favorite bottle ever. Pros: extremely small pin hole in the nipple so small it doesn't flow unless the child sucks. One way valve on bottom eliminates air intake. My child's fussiness from gas bubbles was dramatically reduced, far more than any other brand Very clean ingredients, high quality silicone, sturdy glass do important. Cons: the one way valve comes off the bottom and it's very very small and so easy to loose, I love the fact that it's easy to remove and clean but I've wasted a full bottle thinking I've put the bottom back only to have it leak all over the place The company could do easily give you at least one extra bottom valve it would cost them pennies but they chose not to which is really rotten, for 25 bucks you think they would provide extras, what's worse is they cost 6.99 for two and you have to pay a huge fee for shipping and they are only available on their website so terrible. But despite the selfishness of the company and the risk of losing a piece the size of a quarter it's still my favorite bottle ever because it prevents gas in my baby.

## Questions & Answers

**Q: Why do bottles come in glass and PPSU? How to choose?**
A: Both designs are identical, but glass heats milk faster while PPSU is lighter and nearly unbreakable – both are safer with heat than regular plastic bottles.

**Q: What’s borosilicate glass? Is it better?**
A: It’s extra-tough glass that handles sudden temperature changes better than everyday glass, so it’s less likely to crack.

**Q: What’s the warming base pad for?**
A: It seals the bottle base during warming to prevent leaks – just remember to remove it before feeding your baby.

**Q: Why does milk leak when my baby sucks?**
A: Warm liquid can build up pressure inside the bottle, causing milk to flow through the nipple even without sucking. If this happens, unscrew the cap to release pressure, then tighten it before feeding to prevent fast flow, choking, or spills.

### ⭐⭐⭐⭐⭐ Great bottles for breastfed newborns
*by A***C on December 22, 2025*

These glass bottles have been a great choice for my newborn. The nipple feels very natural and breast-like, which helped my breastfed baby transition easily without nipple confusion. They are well made, easy to clean, and I like that they’re glass for peace of mind. We also noticed less gas and fussiness. Overall, a very good option for newborns.
