Plentyn Newid - Changeling

A changeling is a creature found in folklore and folk religion. A changeling child was believed to be a fairy child that had been left in place of a human child stolen by the fairies. The theme of the swapped child is common in medieval literature and reflects concern over infants thought to be afflicted with unexplained diseases, disorders, or developmental disabilities. In Wales the changeling child (plentyn cael (sing.), plant cael (pl.)) initially resembles the human it substitutes, but gradually grows uglier in appearance and behaviour: ill-featured, malformed, ill-tempered, given to screaming and biting. It may be of less than usual intelligence, but again is identified by its more than childlike wisdom and cunning. The common means employed to identify a changeling is to cook a family meal in an eggshell. The child will exclaim, "I have seen the acorn before the oak, but I never saw the likes of this," and vanish, only to be replaced by the original human child. Alternatively, or following this identification, it is supposedly necessary to mistreat the child by placing it in a hot oven, by holding it in a shovel over a hot fire, or by bathing it in a solution of foxglove.
