As legend has it, female fairies often give birth to deformed children. Since the fairies prefer visually pleasing babies, they would go into the mortal world and swap with a healthy human baby, leaving behind a changeling. While the changeling looked like a human baby, it carried none of the same emotional characteristics. The changeling was only happy when misfortune or grief happened in the house. The changeling legend has lasted for centuries. William Shakespeare talks of a changeling in his play, “A Midsummer’s Night Dream.” Three hundred years later, Scarlett O’Hara believed Rhett Butler’s illegitimate child was a changeling in “Gone with the Wind.”
