My little one is 5 weeks & on size 0 I found size 1 he would choke on his feeds as they were too fast x
It depends what bottles your using
I’m the same with MAM bottles. Little boys on 0 but 1 is too fast…
Of using tommee tippee I found the vari-flow teats best.
I’m using MAM
We started straight on 1 for mam x
We use MAM size 1 since 4/5 weeks old
I have the same issue. I tried the 1 and it made him sick so gone back to 0 x
Wot bottles u using?
