When do we switch to stage 2 bottles?

I did when my son would start playing with it and kept moving around like he was bored. Then when we went to stage two he chugged it down lol

We already did lol that lil boy is on 4-6 oz

@muvamermaid, Chloe is eating 4oz per feeding. But I thought the stages were different for the nipple flow?

she was at 2drips when she was born. when I started giving baby cereal 3-4m that's when I switched to 3drips nipples. now she's at 4drips

They are the flows are different he is too impatient for the 1 lol he can't handle it the 2 works best bc he is greedy and want it now. We just burp him more than once
