A 7-year-old boy usually has excellent grades in school, but he has some quirks that cannot be changed for many years: he likes to chew his nails, and when he is free, he always touches his genitals intentionally or unintentionally. . Recently, Xin Weiwei’s mother took her son Weiwei to the child psychology clinic of the hospital for help.

Weiwei’s fingernails were chewed into uneven spots. Her fingertips, which had been soaked in saliva for a long time, were red and swollen, and the skin had broken out in some places. Xin Weiwei's mother said that her son has liked to chew his nails since he was sensible and has not changed his behavior despite repeated admonitions. In the past two years, the child has developed a new quirk: whenever his hands are free, he will unconsciously touch his genitals.

After Xin Weiwei’s mother was dismissed, Yang Jun, the director of the clinic, began to talk to Weiwei alone. "This is a child who is always nervous about what others think of him." When she was talking to Weiwei's mother, Weiwei, who was standing at the door, always looked in from time to time, eavesdropping on their conversation. Every once in a while, Weiwei would nervously ask, "Is mom okay?" And when she and Weiwei were alone together, she would ask, "Are you happy at school?", "What are you playing with the kids?" Weiwei always answers "Very well" to questions like "Boys of the same age always give lively answers, and the answers are varied, but he seems to be afraid of getting the wrong answer." Weiwei seems like a little adult, but This role seemed to make him very painful.

Through talking with Weiwei’s mother, we found that Weiwei’s family is full of intellectuals, and Xin Weiwei’s mother has been very strict with Weiwei since she was a child. Weiwei started taking various talent classes in kindergarten. She studied English, piano, etc. for three or four years. At most, Weiwei attended six specialty classes at the same time. Usually at home, they also require Weiwei to behave "in line with the rules", and Weiwei has always been a very obedient child.

“Parents have too perfect demands on their children, which puts them in a nervous state of mind. This tension will be expressed through some weird external behaviors.” Yang Jun analyzed that Weiwei Everything is done according to the adults' requirements, for fear of not getting their approval. But this kind of "maturity" does not conform to his true psychological age, making him nervous and unhappy. Biting nails and touching genitals are a behavioral release of pressure. "This kind of psychological pressure formed over many years can easily lead to bigger problems after children enter adolescence." Yang Jun said that in recent years, there have been more and more similar children.
