Use this chart to decrease a behavior that should happen less.
Add treats at a certain time of the day (ours was a lollipop after dinner). Then pick a behavior you want to decrease. Stack the chart with warnings and treats at the beginning of the day. When that behavior happens, your child loses a warning. If they lose all their warnings, the next time they do the behavior, they lose the treat star. If the star is still on the chart after dinner (or whenever you added the treat), they get the treat! If the star has been taken off, they don't get the treat.
