This review is from: Gerber Unisex-Baby Infant Onesies (Pack of 5) (Apparel)
I ordered these size 24mo onesies for my 18mo old daughter. She is a very tall and skinny kid (23lbs) and the 24mo size fits her perfectly. They do shrink a little too. Every size of Gerber onesies I have bought have been a little on the small side.
