I recently heard a woman talked about fighting with her kids because they wanted soda or t. v. on a school night. Then one day she had an idea. She made coupons. She gave her kids twelve coupons that let stay up an extra hour. There were coupons for sodas and coupons for an hour of television on a school night. She gave them as stocking stuffers. The kids loved it. They felt they had some control of their lives and they learned to budget. There was peace in the home. It might be worth a try.
