Have a Christmas snooper who always sneaks a peak of his or her presents before Christmas? My brother was that person and he always managed to sneak a peak at his presents without anyone noticing... well almost. Mom was really good at getting things out of you. She would get so frustrated with him because he was a box shaker, "accidentally" rip the sides of the paper while playing with the cat toys near the presents, and many other ways of figuring out his presents. So one day my ex step grandmother and I put our heads together and started specially wrapping his presents.
If you want loads of entertainment what you do is take a can that you use for the gourmet popcorn, put the present in there wrapped, take all the clothes you bought and line that present, duct tape the top of the tin, and wrap that. Drove him insane!
Second year we started doing the box within a box within a box.
The third year we did a Christmas present scavenger hunt. Boy was he frustrated lol.
Some say this is too much work but trust me the entertainment is really worth it.
