This Rabbit Skins Baby Bodysuit is cute and comfortable. Made from 100% 1×1 baby ribbed cotton, these bodysuits will be one of your new favorites for your baby or grandchild. These have a plastic 3-snap closure that’s softer than metal for easy diaper access, and they feature lap shoulders to make changing that much easier. They are durable and will last through hundreds of washes, but these onesies will also shrink a bit if you have to wash them in hot water to get out juice stains As a rule of thumb, Newborn is 0-3 months and all other sizes are the top of the range (i.e. 6M is 3-6 months).
