This set includes four diapers for changing your Baby Alive doll, which come in handy when the doll "pees" or "poops." These diapers are designed specifically for Baby Alive dolls, which are sold separately and subject to availability. The 4-pack refill is a practical add-on to any Baby Alive doll purchase, letting kids enjoy diaper-changing play again and again. You can also look for other Baby Alive items in the marketplace, such as solid and powdered doll food refills and accessories, each sold separately. This set makes a nice non-candy Easter basket filler for kids.
