Do you have kids that like to shake and guess what their gifts are under the tree? A friend of mine does this cool thing with her kids that prevents them from messing with the gifts under the tree.
She assigns each of her kids a reindeer name and puts that name on the gifts under the tree (she changes their reindeer name each year). She then takes and puts that name on a piece of paper and places it at the bottom of their stocking. Instead of spending their time shaking and guessing what is in the box, they spend their time trying to guess which reindeer they are this year. On Christmas morning, they open their stocking and when they get to the bottom, they discover their reindeer name.
I thought this was such a cool idea. She started this when her kids were in elementary school and still does it today even though they are grown.
