Keep a secret stash of inappropriate pictures waiting for their birthday. This is totally inappropriate, and hilarious.--hahaha, definitely don't show anybody these pictures but would be so funny as a gift for their bday!
Starting in Kindergarten, put the child's graduation year on a large tshirt. Take a picture each year with same shirt to watch the child grow into the shirt. Display at graduation party!-love this idea too bad mine are way beyond kindergarten
