Stuff it with as little or as much absorbency as you need to get you through a quick trip to the store, a long car ride, or maybe even overnight. The diaper has two rows of snaps for adjusting the size as your baby grows. An outer layer of laminated polyester knit keeps wetness in, and an inner layer ofsilky soft bamboo/organic cotton blend.
