establish/make rules
Summarize the rules that you think are important, determine the consequences whenever you violate them, and then tell your children everything.
Believe in children
You should trust the child and hint that he has the ability to do better. In the end, it will also promote children to make better behaviors.
Appreciate praise
You don't have to praise your child just because he says "please", but you should be specific when praising him, not just saying "well done". Instead, it should be said, "Today's clothes are very neat, clean and good." This way, the child will know what kind of behavior you will praise him and why.
Control emotion
Take a few deep breaths before you get angry. If these methods still don't help, you will eventually lose your temper with your children. Remember to apologize sincerely to your child afterwards and tell him that you will make mistakes, but you can admit and correct them.
Reward encouragement
Get into the habit of explaining the reasons to your child after asking him, and occasionally reward his behavior.
