What should I do if a 3-year-old child is not talking?

For a 3-year-old child who is not speaking, the following measures can be taken: 1. Observation and assessment: First, observe factors such as the child's hearing, intelligence, and family environment to determine whether issues like hearing impairment, intellectual disability, or an unfavorable home environment may be present. 2. Medical evaluation: If concerns exist, promptly take the child to the hospital for relevant examinations, such as hearing screening and intelligence testing, to identify any underlying medical causes. 3. Speech training: If medical conditions are ruled out, provide speech therapy by engaging in frequent conversations with the child, encouraging self-expression, and practicing speaking to promote language development. 4. Family involvement: Parents should create a supportive home environment, give the child sufficient attention and companionship, and actively participate in fostering the child's language development.
