we switched to 3s at 3 months. was only in 2s for 2 weeks. He's 6 months now and still in 3s

just depends on weight , my daughter is one and still in 3

5 months and she's still in them at 10 months

About 7-8 months old. I go by the weight it says on the diapers

Thanks ! I just switched my girl to 2 but they dont look as big anymore 😨

my daughter just switched and she was about 7 months old
