First, in infancy, we should correctly guide children to hit teachers with stools when they are criticized by teachers, and express their dissatisfaction in a violent way, which means that children must be like this at home. The reason for this situation may be that parents did not give correct guidance to make children think that they can solve problems by violent means. This is a problem of family education. If you don't give correct guidance and correction, the child may still think so in the future, so the child will suffer.
Second, give priority to with patient guidance, and don't start work. The child has just come into contact with the world and is full of curiosity about everything. If parents want to curb this curiosity and impose their opinions on their children at this time, their autonomy will be limited, and they will gradually become unconfident and have no ability to express themselves independently. In view of this situation, parents should guide their children, patiently persuade them not to violate the rules, which will only cause their children's rebellious psychology.
Third, tell children some necessary rules. Some things, parents should explain the rules to their children in advance, such as not hitting people, communicating with others in time when encountering problems, and not doing things at will. Today's children are relatively independent and have a strong sense of autonomy. We should not impose our ideas on children, but should understand their ideas and think about solutions from their perspective. To establish the necessary rules, tell him these rules from an early age.
