Abiku

A West African demon that tempts children away from home so that it may devour them. This demon has no stomach, and therefore must constantly eat, but will never be satisfied. It is able to dissolve into a puff of smoke, using this ability to gain entry into houses in order to feed on newborns. It is a vampiric spirit, feeding on the lifeforce of living beings (whether they be humans or animals), usually killing them in the process. The Abiku may be banished or repelled by iron, salt, amulets (usually forged of iron, copper, or silver), or greater spirits.
