He is 5 days x
We had this issue and now like Emily just use size 0, they’re slow flow which really helps as our little guy tends to guzzle. He’s two weeks and getting on well with them. Nope that helps ! I got mine on Amazon xxx
I would use size 0 for a few weeks and see how you get on. My daughter is 2 weeks old, and we have just moved to size 1.
How old is he? We use size 0 on mam bottles for my daughter and she’s 10 days old. We haven’t had an issue with winding so far 🤞🏻 x
