when do you start the elf on the shelf

We begin the Elf on the Shelf tradition on the first of December. On this day, we place a tiny elf doll on a shelf or other elevated surface in the home, and each day after that, the elf moves to a different spot while the family sleeps. It's a fun and magical tradition that helps children get excited for Christmas. The elf reports back to Santa each night, letting him know if the children have been good or bad.
