Cloth diapers for newborns are made to fit during the first couple of months of life when regular sized diapers may be to bulky on a tiny baby. Newborn cloth diapers are soft and gentle for delicate newborn's skin and all the adorable little outfits will be fitting just right over these extra small diapers. These diapers are small enough to fit well on a preemie. Many newborn size cloth diapers are designed to fit under the umbilical cord or have a snap down design like Rumparooz Lil Joey or Kissaluvs fitted diapers in size 0. Some of the newborn diapers adjust to accommodate a fast growing baby and last a couple months longer, such as Thursties Duo diaper in size 1 or Happy Heinys Mini. Most economical way to cloth diaper a newborn is to go with newborn size (XS) diaper covers and preemie size prefolds. Thanks Mama has a number of Newborn Diaper Packages to choose from.
