Last year we were introduced to this book "Elf on the Shelf" and made it a Christmas tradition from that point forward.
We love our elf which the Red's named "Portie" last year. Santa sends him around Christmas time every year to watch the happenings of the house and report back to him. Portie shows up in a different spot everyday and sometimes gets into mischief. Every night he flies back to the North Pole to tell Santa how the Red's were and what they have asked for.
The Red's love it and on some days it helps to get their attitudes in check!
The rules are you can't touch him and he can't talk to you......but he listens and watches and then tells Santa.
I have seen them at Books a Million and Barnes and Noble. If you don't have this book and you have kids, it's a must have! The Red's have talked about Portie all year long and couldn't wait for him to return again!
