I am wondering this for two reasons.. 1) I have 2 boxes of size 4 diapers and I was wondering what age babies often grow into them, or if maybe I should try harder to exchange them for a smaller size.. LO wears size 3 and they fit a lil big still. She weighs 18.5 pounds...Friends of mine with almost 2 year old babies are wearing size 4, but they seem to maybe be on the smaller size? 2) SIL has a lo bigger than my lo in size 1 diapers! I was just surprised - no other reason for mentioning this lol
Re: What size diaper does lo wear?
I would just keep them I guess if i were you.
Definitely take their build into consideration
