What should I do if a four-and-a-half-year-old child cannot speak

When a four-and-a-half-year-old child still cannot speak, parents should remain calm and seek professional help as soon as possible. This may be related to delayed language development and requires ruling out organic factors such as hearing impairment or abnormalities in oral structure. Parents should actively communicate with the child, using simple and clear language, and encourage the child to imitate sounds and expressions. Meanwhile, activities such as storytelling and singing can be used to stimulate language development. It is important to provide the child with sufficient love and patience, avoiding excessive anxiety and pressure. Professional assessment and intervention are crucial to help the child achieve normal language function as quickly as possible.
