How long do babys usually stay in 12 mo clothing?

We will be in 12 month for a long time

Oh wow @karensmommy, @deckroth2001, okay wanted to see if there grow spurts slow down a little at one and how much 12 months clothing you should actually buy (if they will only fit it for a few months or longer)

My baby is 1 year old. 9 month to 12 month clothing and 18.2#s

Mine was in 12 month clothes when she was 6 months
