Establishing rules with children is an opportunity to teach the meaning behind them. For example, rather than telling your child "no running" at the swimming pool, point out the sign. Explain that this rule is necessary because the lifeguards are in charge of everyone's safety, and that water makes the surface next to the pool slippery. Some children may want to discuss possible injuries; other children may want to discuss why water makes cement slippery; and still other children may agree to follow the rule just so they can go swimming.
