The Rumparooz Lil Joey All in One (AIO) Cloth Diaper fits babies 4-12lbs. and is a perfect solution until your baby fits into a one size diaper. They are very trim and not bulky. Since these diapers are AIO cloth diapers, there is no need to stuff or add inserts making it the perfect diaper for grandparents and caregivers! A 4-layer soaker is sewn to the waterproof cover. The inside fabric that touches your baby's skin is hypo-allergenic and made out of no pill micro-chamois, which is extremely soft. The Rumparooz patent pending double inner gussets keep in blowouts. There is also an umbilical cord snap down option that will not irritate your baby's umbilical cord. It adjust to two sizes and comes in packages of two. I fell in love with these diapers the first time I saw and touched them. Different Diapers offers a Newborn Rental Package containing these diapers!
