Thread: "Are Avent nipples as bad as everyone says? "
For various reasons I prefer glass bottles so we went with Avent natural glass. Both kids had no problem. They do work differently than other nipples bc baby has to work, but I don’t see that as a problem
Thread: "Best bottles for preemie babies"
Same. Dr Brown's were good for pace feeding, because the OT taught us to hold the bottle like a pencil. That wouldn't have worked with wider or heavier bottles. We switched to Avent Natural Glass as soon as possible though. ETA - If you want to breastfeed you should pick a bottle that let's the baby get a deeper latch. The Lanisoh ones and Evenflo Balance are supposed to be the best for that and the Dr Browns are good too. The problem with bottles like the Comotomo, they look more like a boob, but they actually encourage baby to latch really shallow. Full disclosure though, I'm not breastfeeding and I like the Comotomo bottles otherwise. I'm hoping to switch to them when my baby is able to hold his own bottle.

Avent natural glass! I have cute silicone sleeves for them when taken out or used around the house. They’re awesome.
Thread: "Are Avent nipples as bad as everyone says? "
We used these glass bottles for both kids and went right to a size 3 with our first because he was combo fed. With our second, we went right to size 4 because she was bottle fed from the start. All the sizes before those were too frustrating for either of them. Otherwise, love these bottles.
