Tell them the rules in advance. Once you recognize a misbehavior pattern, establish a plan. Provide support and encouragement. Use charts and contracts to strengthen your plan. Use punishments that teach decision-making and accountability.
Children survive reasonable punishments, such as restriction and time-out.
Do not punish when you are angry. Do not punish to get even. Relate punishment to your child's decisions about misbehavior. This teaches responsibility. Begin teaching responsibility and decision-making when your children are young.
