What size diapers are your 3-4 month olds wearing?

Betty
I just picked up size 4 pampers swaddlers for my very tall little man. He will be 4 months old on January 3rd. I know he's tall for his age but I feel like he's growing way to fast!!! What size are your little ones? He's already outgrowing his bassinet Mammas not ready for this! 😢
