I would not do this to my children as they are great kids and they are that - KIDS. I am sure Santa will make it to our house.
Anyone that hasn't seen this http://www.portablenorthpole.tv/home Should really check it out. Our kids were responding with head shakes, yes's and smiles when they saw their video messages, it even rang true with the Girl who is 2 1/2. For the Boy who is 6 they even showed Santa's path to our city which was pretty Nick and he got a great appreciation out of that, plus he saw Santa had photos of him from the year and was a little surprised Santa was watching that closely. Too bad Santa didn't use the Photo I posted a few days ago of the kids with the train.
We will soon put out our reindeer food and wait for the jolly old man to visit. Merry Christmas.
