I am thinking of setting up star charts for both kids for doing various things. Tell me how star charts have worked for your kids- what the basic ground rules are (ie what earns a star), how often you give incentives and the big one- what incentives you give. I'm thinking perhaps extra screen time for DS (he's 5) but DD won't really understand that concept as she's only 2.5. I don't want to use food or toys as incentives.
Ideas and words of wisdom please!
