I ordered the 1-2yr for my 22month old and the bottoms were the same 6-24month bottoms that came with the smaller one I ordered for my 6month old. They were snug but worked just fine for a picture. Diaper was able to be tucked in and we were good! Couldnt get him to set next to his little brother nor smile in a pic with him but, the outfits were adorable nonetheless AND the photographer liked them so much she bought them from me. So it was a Win Win!
