"If the "intentional damage" behavior is caused by factors such as curiosity, exploratory mentality, blind simulation mentality, etc., parents do not need to panic. These destructive behaviors are manifestations of lively thinking in young children. For the widespread unhealthy psychological behaviors in young children, many parents let them be, thinking that children will naturally correct them when they grow up. In fact, this view is inaccurate. For the health and happiness of children, adults must pay attention to the children's unhealthy psychological behaviors and correct them in time. The main points of unhealthy psychological behaviors in young children are as follows: 1. Biting fingers: This is a typical sign of anxiety and mental tension. This behavior usually reflects the lack of security in the child's inner heart. 2. Picky eating: This is a common bad eating habit among young children. The result will cause nutritional imbalance or loss of appetite in children, seriously affecting their growth and development, and also affecting their mental health. 3. Lying behavior: Most young children lie, but the motives and types are different. There is a mixture of imagination and reality; some consciously lie to achieve goals, etc. 4. Aggressive behavior: The main causes include learning through media, influence from the teaching methods of family elders, and inappropriate teaching methods of teachers, etc. 5. Withdrawal behavior: It is manifested as timidity, loneliness, lack of interest in others, unwillingness to interact with other children, emotional instability, mood swings, and crying or laughing for no reason. 6. Destructive behavior: The "destructive behavior" of young children can be divided into two categories: "unintentional destruction" and "intentional destruction". "Unintentional destruction" behavior is mainly caused by physiological reasons and can gradually decrease with age. If the "intentional destruction" behavior belongs to revenge, venting, jealousy, rebellion, arbitrariness, and meeting personal needs, parents and teachers must pay high attention."
