The kids worked hard today. They finished their homework, they ate all of their dinners, and they cleaned up after themselves. They get rewarded for doing good work. They get lots of praise and maybe event get a treat.
They get to do fun things with the sitter. They get to buy some small favors. They do enjoy that. It is better than buying them a brand new toy every time they want one.
We do like to give them little stickers on the calendar when they do what we ask of them. When they do what is asked they get a small reward. Both of us have to be on the same page in order to have success. My husband and I have to work hard to ensure that the system works. There is no reward without work. That is true of most things in life.
