In the vicinity of Hanover, Germany the Wends (Western Slavs) had belief in a special type of vampire which they called the doppelsauger, a German name which literally means "double-sucker".
He supposed to be the revenant of a child who again sucked his mother's breasts after he had been weaned. If such a child dies, then in his grave he consumes the flesh of his own breasts. Then it preys on a living member of his family, causing the person to rapidly lose weight.
Preventive measures at the of such a child include:
- Placing a coin between the teeth of the corpse.
- Placing a semi-circular board under the chin of the corpse so that the mouth cannot reach the chest.
- aking sure that the cloth of its burial garments do not touch the lips of the corpse.
