1. Children enter junior high school and are all in adolescence. At this stage, children will experience the second peak in their lives, and their height and weight will increase greatly. At the same time, their psychology has not fully adapted to their physical changes, resulting in an embarrassment and sensitivity, which leads them to be introverted and unwilling to associate with others, even their parents.

2. The child's personality is constantly formed and developed in communication. Parents should let their children make more friends, and when they play with friends, their children will be more cheerful and outgoing, thus gradually internalizing their own personality. Contradictions in communication with friends also enable children to learn to resolve contradictions, face various changes and gradually adapt to the changing world. In this way, even if the child goes to junior high school, it will be better for parents to adjust slowly, and it will be better after the age.
