We loved having Christopher around this Christmas :-)  He definitly didn't help my 4 year old behave any better, well maybe for about a week, but it was soooooo fun hiding him when my son was sleeping or playing or out of the house.  We would be driving home from somewhere and my little guy would say out of nowhere "wonder where Christopher will be hiding when we get home?" and he tries to beet us in the house running from room to room, precious memories.  Worth it even if it is for 1-2 Christmas'.
