To make a baby diaper cake, stack concentric rings of rolled diapers around a bottle of baby lotion, decorate the cake with ribbon, and garnish it with small toys or a baby blanket. The supplies you need include diapers, rubber bands, a cake plate, baby lotion, ribbon and scissors.
Purchase a large box of infant diapers and roll each diaper into a tight tube. Secure the rolls with rubber bands at both ends. Set a cake platter on your work surface, and put a bottle of baby lotion in the center. Surround the bottle with a ring of diapers standing on one end, and tie them in place with a rubber band. Surround the diapers with two additional rings of diapers, and secure the outer layer with decorative ribbon. This is the first tier of the cake.
Begin the second tier by placing a ring of diapers around the upper half of the baby bottle. Slip a rubber band around the ring, add a second diaper layer, and tie ribbon around the second tier. Add a third tier if desired.
Tuck miniature stuffed animals around the base of the cake, and top it with a toy or another stuffed animal. A small baby blanket is another appropriate decorative option.
