Family Rules Would you like to have a boss who didn't specify what the rules were in your work place but punished you if you broke these unknown rules? You would feel pretty frustrated, wouldn't you? That's how children feel when they are punished for breaking rules that have never been explained to them. Family rules are necessary to make clear what is expected of children and to outline punishments for misbehavior and rewards for good behavior. When creating a list of family rules remember to be specific both in what is expected and the punishment or reward. Gather the family together when creating the list of family rules. Involve children in the creation of the rules and get their input as to appropriate rewards or punishments. Explain to children why youd like to include certain rules. They'll accept them more if they understand that they are for their own benefit and safety. You can create the list of rules in the form of a contract which all family members sign. Before completing the contract make sure that all family members are in agreement as to the wording of the rules and the punishments or rewards for each rule. Once the rules have been created, remember to be consistent with their enforcement. The list of rules doesn't mean anything unless it is consistently enforced. 1. Why do we need a list of family rules? 2. Why should we explain to children the reason behind the rules? 3. Who should sign the family rules contract? 4. What could happen if you don't consistently enforce the rules?
