There is a Christmas tradition with elves - Elf on a Shelf - maybe you have heard it, maybe not. Some families have an elf that reports to Santa on how the kids are behaving at Christmas time. The parents move the elf throughout the house and their kids look for these elves each day to see where it has moved. I don't go that far b/c I know I'd forget. However, it is a great idea, and if it makes your kids behave - even better!
