You give your child information. Then she has a chance to figure out for herself what to do. Not only do you avoid the natural resistance that comes from a direct order, you’re also laying the groundwork for your child to develop the ability to exercise self-control, whether or not there’s an adult telling her what to do. A valuable lesson indeed. You’re offering your child useful knowledge for the future, in place of a rule that might be followed only when you’re around to enforce it.
