Children's lack of self-confidence is a manifestation of sensory impairment. I suggest you take your child to a professional evaluation. My little nephew just lacks self-confidence, but he is too introverted to communicate with people. Later, my sister took him to see a doctor. The doctor said that the child may have sensory impairment. Later, I took her to Zaion and Shenzhen Nanshan Baoneng Taikoo Shing for a period of time, and the effect was very good. The child is confident, too. You can take her to see it ~ adopt me ~
