The abnormal behavior of a child who is timid, afraid, lonely, and unwilling to make friends with other children, much less go into unfamiliar environments, is known as withdrawal behavior. The formation of a child’s withdrawal behavior is related to the child’s natural temperament, parenting attitudes, family environment, frustrated interactions with partners, and other factors. (1) the basis of temperament: some children are born with the temperament characteristics of retreat, they first meet strangers, new things or to a new environment appear to cower, avoid the look, but in fact still willing to interact with people, accept new things, new environment, but the enthusiasm is slow to start, need a long time to adapt, if the lack of encouragement, or even be blamed, the child’s heart gradually formed desire will be easily suppressed. If there is a lack of encouragement, or even blame, the child’s gradually formed desire will be easily suppressed back, the formation of withdrawal behavior. (2) Parenting style: Some children are too spoiled at home, any requirements are unconditionally met, so they are excessively self-centered, self-care ability is very poor, once they enter the collective environment is overwhelmed, especially when the behavior is restrained, criticized by teachers, children ridicule, easy to produce fear, reluctant to go to kindergarten or school, reluctant to interact. Some parents are always too strict with their children, often chastising them, so they lack self-confidence from an early age, and are prone to withdrawal for children who are sensitive by nature. (3) Family environment: Some children are influenced by the parents’ withdrawn personality, lack of contact with the outside world since childhood, poor adaptability, do not know how to interact with others. Some parents often quarrel in front of their children, fights, divorce, family conflicts and even take the child out, so that the child grew up in fear, become timid, fearful, withdrawn. (4) Interaction frustrated: Some children do not retreat in the original environment, but after entering a new environment due to their own defects (such as obesity, stuttering, etc.) or other reasons (such as to foreign or foreign, language barriers) can not be treated fairly, often ridiculed, bullying, fragile self-esteem suffered a blow, so the formation of retreat character and behavior. Some sudden events can also cause temporary withdrawal, such as the sudden death of the closest family members, their own accident, etc. If the child can be given timely moral support will soon pass, otherwise it will also affect the long-term character of the child.
