What happens when a child is weaned before its time and dies as a result?
In the Dalmatin region of Croatia the dead child becomes a a Kozlak.

4.2.7

The Kozlak raises from the dead and acts like a poltergeist breaking and throwing kitchen items, shape-shifting unto a bat or carrion animal. It will attack live stock and feed from it.

While in a solid but nondescript form it can be hypnotized by a branch of Hawthorn. While in a trance it can be stabbed in the heart with a branch of Hawthorn or a ritually blessed daggar. Its best if a Franciscian monk does the killing.
