This busy wallet is GENIUS! Especially for the kids at the restaurant while you're waiting for your food: Pick up a cheap wallet. fill it with pictures, scrap paper, stickers, and various treasures. My girls would LOVE this!
Rewarding kids with things they get to do instead of things they get to have. When they do something good, they pick from the jar and get things like to stay up a little later or play outside a little longer etc.
