Ah, the Elf on the Shelf! A classic tradition of hiding a mischievous elf around the house to keep an eye on children during the holidays. The best way to introduce the Elf on the Shelf is to explain that he is Santa's helper and will be watching to make sure everyone is being good. Remind them that they'll need to be on their best behavior if they want to receive presents from Santa! The Elf on the Shelf is a fun way to add a little extra magic and excitement to the holiday season.
