BumGenius easily fits babies from 7-35 lbs. by changing the snaps on the front of the diaper. With multiple children in diapers, your diaper stash will be simplified by being able to use the same diaper on different sized babies.
Fitting from 7-35 lbs. BumGenius One Size come with two inserts - the amazingly absorbent Cotton Babies One Size Microfiber Insert (can be three different lengths 15"L, 13"L or 11"L x 5"W - three layers of micro terry) and a newborn size (11"L x 5"W - 2 layers of micro terry) insert for a trim fit on your recent arrival. The newborn insert can be used with the larger insert when your older baby needs more absorbency.
Diaper Cover Quick Guide
The top front of the diaper has an insert stop feature to keep any wetness from wicking onto clothing. For newborns, the top front of the diaper can be folded down to keep the umbilical area clean and dry.
Three snap-downs on the front of the diaper allow adjustment of the rise as your baby grows. Rolled out leg casings to keep the poo in and to help keep red marks away!
Super stretchy, ultra gentle leg and back elastic.
