Sizes 6M - 3T. We've given the classic baby romper a MODKID touch and updated it with some fun details for both boys and girls. Our fully-lined romper means there are no itchy and scratchy exposed seams, plus it looks super cute when the inside fabric peeks out. The romper hits mid-thigh and three snaps in the crotch area make for quick and easy diaper changing. You will want to make this easy project again and again since it comes in infant to toddler sizes to grow with your growing child.
