Children can usually speak at the age of 1/3 years old. Some speak later, but they can definitely say some simple words, such as mom, dad, etc. If your child is not talking, it may be due to the following reasons. Tongue tie is too short

Please rule out whether the tongue tie is too short. If so, please ask an otolaryngologist to perform tongue tie amputation. Poor hearing

To rule out the problem of poor hearing, because "ten deaf and nine are dumb", it is best to ask an otolaryngologist to check your hearing. Excessive dialects

Exclude the situation where there are too many dialects in the family. In this environment, children will be at a loss as to which dialect to learn. Brain dysplasia

After ruling out the above conditions, please rule out brain dysplasia. If the child has an abnormal birth history such as asphyxia, intrauterine distress, umbilical cord around the neck, turbid amniotic fluid, etc., it should be ruled out. Head CT can be done to exclude. But if there is indeed brain dysplasia, it is recommended to carry out rehabilitation treatment in time. Autism

Autism may still be related to an abnormal birth history. In this case, it is best to ask a psychologist for help.
