We just got our Elf on the Shelf this year. It took the boys forever to decided on a name, they finally decided on TJ for Tanner and Jayden.
For those that don't know... This Elf on the Shelf comes with a book telling all about him, that you can read to your kids. I bought mine at AC Moore craft store but I've also seen them at Target. You have to name your Elf and register him or her (you can also buy a girl) with the North Pole. The kids are not allowed to touch him but I had to make an exception for Mackenzie and told the boys that babies didn't count. If a child touches the Elf he looses his magically powers and can't return back to Santa. Each night the Elf returns to Santa and reports on how the kids were behaving, whether they should go on the naughty or nice list. And when he returns he's in a different spot in the house and the kids race to find him. The kids are encouraged to talk to the Elf, but the Elf is on strict orders not to talk to the children.
This was our first morning with the Elf, and this is what he was doing.
