The Elf on the Shelf is a holiday tradition that started in the United States. The Elf is a small doll that comes with a book. The book tells the story of how Santa Claus sends a Scout Elf to each home to keep an eye on the children and report back to Santa each night. The children name the Elf and take care of it, and each night the Elf moves to a different spot in the house to keep an eye on things.
The Elf on the Shelf tradition is meant to encourage children to behave well during the holiday season, as they know the Elf is watching them. It’s also a fun way for families to countdown to Christmas, as children search for the Elf each morning and look forward to finding it in a new spot.
