1, let children learn to express: for example, buy some reading materials to let children know that they can speak and express their emotions, so that they can effectively vent their negative emotions, instead of throwing things, hitting people and getting angry to vent their anger, complaints and dissatisfaction. If they can't express their emotions, they will easily get grumpy, which requires parents to guide them and let them know in the process of interaction with their parents.

2. Parents should trust and tolerate their children more: give warmth and empathy. When the temper is bad, the child will also be hurt by emotional instability. Therefore, we should also know that children may lack the skills to express emotions, or the nervous system is immature. The younger the child, the easier it is to get grumpy. At this time, we need to give stable encouragement, care and positive attention, so that they can establish a very stable attachment relationship, which can gradually reduce the problem of children's bad temper.

3. Try to be friends with children: communicate in an equal and respectful manner, so as to establish a very good relationship or friendship. Only by establishing a very good relationship can we influence children, or let children understand that grumpy can't solve the problem, and grumpy will hurt the relationship with parents and other children, so that they will slowly learn to grow up, learn to express their emotions very accurately, and reduce the appearance of grumpy.
