America's favorite bodysuits, times 5. THIS is the Original Bodysuit™. Over 43 million worn and loved this year alone. What most people do not know is… the overlap shoulders can expand down over baby’s body in case of a diaper fail. Life. Saver. We recommend starting with 2-3 long and short-sleeve multipacks. Multipacks are a must! This is your diaper bag backup. Stock up on some pull-on pants to pair with, also sold in multipacks. Everyday outfits, done.
