A two year old child not being able to speak is usually an anomaly. It may be due to hearing impairment, imperfect language development, child autism and other reasons. 1. Hearing impairment: hearing is an important channel for language perception. When a young child’s hearing is impaired, whether conductive or sensory-neural, he or she cannot correctly perceive sound conduction, resulting in varying degrees of delayed language development. 2. Delayed brain development: Delayed brain development may also affect the language system. This will cause delay in the development of the language center, which will result in the child not being able to speak at the age of two. You should go to the hospital in time, according to the guidance of professional doctors for language rehabilitation training. 3. Children’s autism: It is also possible that autism is the cause of not talking. The main manifestations are social disorders, communication disorders, stereotyped repetitive behaviors and so on. This situation requires targeted treatment according to the specific symptoms and performance of the child. Therefore, the child should be taken to the hospital for examination in time. Parents are advised to take their babies to the hospital for checkups in a timely manner to find out the specific reasons for their babies’ inability to speak, and then treat them according to the doctor’s advice and in conjunction with their babies’ conditions.
