The timing of a child’s speech is often related to individual differences, life environment, genetic factors, and many other factors. Some children’s speech systems develop faster and can express themselves more clearly at an earlier age, while some children may develop more slowly, but this is usually normal as long as there are no pathological changes. In general, children can babble at 3-4 months of age, say simple words at about 12 months of age, usually say 15-20 words at 18 months of age, and can say and recognize the names of key family members, probably say simple names of people or names in pictures at about 2 years of age, express themselves in short sentences at about 3 years of age, and tell stories at about 4 years of age. At about 4 years of age, the child is able to tell a simple story. If parents find that their children are late in speaking, it is mostly related to physiological and pathological factors: 1. Physiological factors: Children’s language development may be related to individual differences, living environment, genetic factors, etc. Some children’s speech systems develop faster and can express themselves earlier, while some children may develop more slowly. Parents and people around them are important initiators of children’s language development. It is recommended that parents communicate with their children more often, do not be overly anxious, patiently cooperate with the child’s speech development process to teach speech, do not just do unilateral speech output, but communicate with the child reasonably, so as to promote the child’s language development; 2. Pathological factors: If a child has a language disorder, it is necessary to consider whether it is caused by pathological factors Caused, the child may affect the speech development if he or she has dysarthria of the constructive system, such as vocal cords, tongue, soft palate, mental retardation, hearing impairment, cranial nerve injury, has autism and other mental disorders.
