Now when people in line at the grocery store look at your precious little girl and say, "how old is HE", you can point to her XX chromosome onesie and say..."Clearly you didn't pass biology class. As if the pink bow and skirt didn't make it obvious enough...SHE is 6 months old."

Chromosomes are printed on a white onesie. Sizes below, please be sure to note the size you want upon check out!

Newborn: up to 13 lbs
