I’ve found a fun holiday tradition I want to start with my son: The Elf on the Shelf tells the tale of Santa’s Elves who keep an eye on kids during the day and report back to Santa at night, keeping Santa in the know when it comes to tracking who’s naughty or nice. The set comes with a book and an elf that you move around the house each day, inspiring (or frightening!) your kids to keep up the extra good behavior during the holidays.
