Uldra, The Little People of Lapland, are found in the far north of
Sweden. They are normally found underground, but emerge during the
winter to feed hibernating animals. They are usually indifferent to
humans but may take revenge if wronged. Normally they will only
poison a reindeer, but if very angry they will steal a baby,
replacing it with a black-haired, sharp-toothed baby uldra. The
methods of retrieving the human baby are similar to those used to
retrieve children stolen by other faeries ,
including such drastic measures as beating the child with a burning
tree branch until the screams cause the mother to return for it. A
contrary opinion is that the child should be treated with great
kindness, and in gratitude, the mother will return for it and bring
the human child back as well.
