If the child’s mind is lower than that of his or her peers, the following measures can be used to deal with it. First, lower expectations. Because the child’s mind is lower than that of children of the same age, high expectations for the child can cause irritation to the parents and psychological stress to the child, which is not good for the child’s physical and mental health. Secondly, the child should be given timely rehabilitation training. If the child’s mental ability is below that of his or her peers, the child needs to be rehabilitated so that he or she is basically the same as his or her peers. Finally, the child should attend a special school. If the child is significantly below his or her peers, he or she should attend a special school, otherwise it will be difficult for him or her to learn and progress at the same time as the children of the same age.
