The baby is three years old and can't talk. First of all, we should go to the hospital for CT examination, intelligence test, physical development test and various auxiliary tests to see if there are brain diseases, congenital genetic diseases, developmental retardation and nutritional disorders. These all affect the baby's language development. The elimination of these diseases depends on the language environment at home. In the family, some people speak dialects and others speak Mandarin, so that children don't know who to learn well with, which will also affect their language development. Therefore, families should create a good language environment and patiently teach their babies to learn to speak. In this case, it is best to find out the reason why the child can't talk at once and treat it as soon as possible, so as to achieve good practical results.

If the three-year-old baby can't talk, we should find out his reasons as soon as possible from the following aspects: First, find out the reasons from parents; Lack of language environment. Everyone in the family is very busy, so he has no time to teach him to speak, and his family seldom speaks, which makes him live in a poor language environment and can't speak.

2. Pay attention to the family atmosphere. If the family atmosphere is not good, parents do not teach their children to learn to speak, do not often learn to speak with their children, do not teach their children to speak, and do not communicate with their children, the baby may not be able to speak.

Self-test method: Parents can record the times and time of talking with their children every day. If you talk for less than half an hour every day, then the problem is with you.

Second, find the reason from the child 1, and ask the doctor to check whether the child's pronunciation organs are abnormal, such as whether the tongue is particularly wide and short; Whether the palate, teeth or lips are deformed;

2. Children are prone to autism, such as autistic children who can't talk.

3, the child's hearing is impaired, if the child's hearing is impaired, it will also cause the child to be unable to speak.

4. The child has problems with the development of the lingual frenulum. If the lingual frenulum develops abnormally, it will also cause the child to be unable to speak.

5, the child's nervous system development is abnormal, especially in the case of asphyxia, hypoxia and brain injury after birth, the child's brain cells are damaged, which can cause language development retardation.

Third, parents should guide their children to speak in the following ways: 1 Parents should consciously talk to their children and imitate them more. For example, let the child sit on the leg, the mother points to the apple, let the child touch the mother's lips and nose, and then say "apple". If the child is right, give some small rewards.

2. Delay meeting the child's requirements, try to let him say it, and then give it to him.

3. Combine the child's speech with the game, such as "the baby catches the ball"; When dressing, say "the baby's arm is stretched out" and "the foot is out" every day, so that the child can connect his feet, arms and legs.

4. Create an environment for communication with children. Children of similar size often play together, not only having fun, but also learning from each other in communication.

5, can give children early education classes, systematically develop and train children's various abilities.

Parents should encourage their children to speak, try to let him speak naturally in a relaxed and pleasant atmosphere, teach students in accordance with their aptitude, guide them patiently and persevere. If the child still doesn't talk when he is 3 years old, he should go to see a doctor, and then teach according to the reason why the child talks late after eliminating physical illness.
