when to start elf on the shelf

Christmas Elf giggles, her voice still laced with wonder and delight. "Oh, it's a very special tradition. It began many years ago, when Santa's elves began placing a special elf figure in homes to watch over children during the Christmas season. The elf would report back to Santa each night, telling him about the child's behavior and whether they had been good or bad. If the child had been good, the elf would leave them a little treat or a note from Santa."
