Philips Avent Natural Baby Bottle Newborn Flow Nipple, 0M+, 4pack, Flow 1, SCF651/43

The newborn version(0M) allows too much formula resulting in a messy feeding. Additionally, it adds too much bubbles, which causes newborn to have more gas discomfort. Have set these aside and will revisit when baby is a bit older. Otherwise, product is well made and good quality

Very thick and sturdy for baby. A bit expensive, but I love Avent bottles. Easy to clean if you have a bottle cleaner.

My baby eats a lot and she blew through a 4oz feeding pretty quickly. I ordered some 11oz bottles just so they would last throughout the rest of the time she would need a bottle, but those come with size 4 nipples so I bought these for her. They do leak more than the size 1s that come with the smaller bottles, and for some reason for 3 of the 4 the tip of the nipple does get sucked inside multiple times while baby is eating, which I dont necessarily hate because my baby has reflux and we need to burp after each ounce anyway. But it is very inconvenient, and if I didnt need to make the baby take breaks I could see myself being highly annoyed and pissed off by it.

Great product! Slowest flowing nipple on the market. Great for newborns

These are much thinner than the Avent Natural nipples I previously purchased. They collapse frequently, it seems due to poor venting. I dont hate them enough to return them but I avoid using them as much as I can and do not recommend them.

Great! I use this size nipple for my newborn and he’s now 6 months and still using it — no need to make milk come out faster as he’s breastfed and used to working to make milk flow.

These are the best nipples we have tried and our 5 month old is still using them.

Love all avent products! I used them since O had my first baby.

These are awesome, just what I expected.

Bought these for my newborn and thought they were level 0 not level 1. We tried it and he did nothing but choke on it so we’re back to one level 0 nipple.
