Take a picture of your child while they are sleeping after they lost a tooth. Then, go to this website where they'll put the "tooth fairy" in the picture with them! Very cute. I'll have to remember this one day!
Scan childrens art work and then print out in smaller size. Frame. Now make art gallery in hallways of your childrens art:). Awesome idea, even for my grown young adults to have all of the kept keepsakes of their artwork in one frame. Good Christmas or Birthday gift.
