Thanks guys

my son is 14 sounds and in size 3 because the poop was coming out his diaper in size 2

every baby is different. if baby is leaking out of the diapers that's a sign it may be time to go a size up. you can also go by the weight for the size of the diapers. my baby is 6 months and in size 1 still. she's petite though

My son will be 1 tomorrow and he's still in size 3s.. so I wouldn't worry. His pediatrician said that he's healthy he just has a little booty lol

My baby was about 2 months 11 lbs

My son was 2 months old when he started size 2
