The Changeling
The changeling is a common theme in folklore and refers to a child that has been secretly substituted for another child. The changeling is often believed to be a fairy or supernatural creature that has been left in place of a human child. The story of the changeling typically involves a family that has a child who becomes sick or behaves abnormally. The parents may believe that their child has been replaced by a fairy or demon and seek out ways to identify and remove the changeling. One common method is to place the suspected changeling near a fire or hot object to see if it reacts in pain or discomfort. Another is to give the child a bitter or unpleasant food or drink, as it was believed that changelings had an aversion to such things. The changeling story can be found in many cultures throughout history and its theme has been used to explore themes of identity, family, and the supernatural.
