How long do babies wear size 1 diapers?

Thanks everyone

My son is 3 months and they still fit... Barely but I have sooo many so I'm using them damn it!

My baby is 2 months and still has a ways to go before they get too small. Hard to say as every baby is built differently.

my almost 8 month old is still in size 1

depends how big they are and how fast they grow , usually not very long

My daughter wore them until she was 2 months.
