i LOVE these onesies! I have bought them in each size group for my son. (he's 9 months now) He wears them under is jammies or during the daytime. They are SO soft and cuddly! And the colors are vibrant and the patterns are fun! Plus they have 'grow with me' snaps, so there are 2 sets of snaps at the crotch so he can wear them longer as he grows taller!
