To get an Elf on the Shelf, you'll need to follow the traditional process. First, make sure your home is properly prepared for the arrival of an Elf. The house should be clean and organized, and there should be a special spot for the Elf to sit. Next, write a letter to Santa requesting the Elf on the Shelf, and be sure to include your child's name and a description of your child's behavior. Finally, set out a plate of treats for Santa and the Elf on the Shelf, and make sure to leave some milk or water for them to drink.
