Potty training is often one of the most difficult developmental hurdles of early childhood, but it doesn't have to be. This fun-theme rewards chart is easy to use, promotes good habits through positive experiences, and features your child's favorite Teenage Mutant Ninja Turtles. Simply place a pizza sticker in the box every time your child goes or attempts to go potty, in order to help Donatello deliver the pizzas to the other turtles. The best part? This chart hangs on the door handle, so you can chart your progress right on the bathroom door. The chart unfolds to provide over 50 reward spaces and also includes 50 additional reward stickers so you can track your progress each and every time.
