If you find it fun to make-believe that Santa delivers presents, find a way to introduce reality to your kids in a way that they participate in being 'Santa'.
This is a great idea, but if you have strong willed child, be careful. A couple years ago, probably when DS was 11 or so, I enlisted him in helping me find and wrap presents for Santa to give. He helped me wrap them and label sock with the adults names on them so I could put them out on Christmas night after he was asleep. But he stayed awake and refused to go to sleep. At about 1 am when he was still wide awake, I allowed him to put the adults suprise stockings out. He loved it. Since then, I have made all the adults in the house pretend to go to bed early so he can hide the stockings. Then the adults get back up again after he is tucked safely in bed again.
That boy has a strong will!!!
