(1) Moderate punishment: it can be serious criticism, or it can be to let him go back to his room and think behind closed doors, or forbid him to play toy games. You can also beat and scold if necessary, but not too hard. The purpose is to let him know that you are serious.

(2) Firm attitude: It is stipulated that no bargaining is allowed. Don't threaten or warn too much, and don't threaten unrealistic or incomprehensible warnings. You can't do it. You must keep your word, let the children learn from it, and keep your word.

(3) Work out a code of conduct plan with children: once it is made, it will be resolutely implemented. Give timely encouragement to those who perform well, and criticize or even punish those who perform poorly.

(4) Try to avoid using the name "bad boy": you just want him to know that you disagree with his behavior and explain the reasons, not that you don't like him.

(5) Children should be rewarded for their progress: rewards can be material, such as his favorite toys, musical instruments and story books, or spiritual. But the prize must be given after the goal is achieved to show the reward.
