The Elf on the Shelf tradition is a fun and magical way to bring the spirit of Christmas into your home. Every night, the elf hides somewhere in your home and watches the children to see if they are being good or naughty. In the morning, the children look for the elf to see where he has moved to, and if they've been good, they might find a note from the elf, a special treat, or a little gift. The elf is a fun way to add a bit of magic to the holiday season and keep the children excited and on their best behavior!
