The Lil Joey is a newborn diaper designed to fit from approximately 4-12lbs. The inside of each diaper is designed with 2 gentle inner gussets, a double barrier that channels each leg. The Lil Joey takes special care with a snap down front for sensitive cord care during those first precious days. The Lil Joey is the simplest of diaper systems on the market for a newborn baby. The internal soaker is 4 layers of thirsty microfiber that have been permanently sewn into the core of the diaper, no stuffing required. The Lil Joey is waterproof and requires no cover.
