Children with slurred speech should have the cause of the slurred speech identified. If it is a cranial dysplasia go to a neurologist. If it is a tongue-tie problem, go to the stomatology department. If the child has mental and motor developmental delay, and also has unclear speech, then it is necessary to go to the neurology department of the hospital to do a cranial magnetic resonance imaging (MRI) and intelligence testing, and actively carry out rehabilitation exercises. If it is determined that the child’s tongue tie is too short, he or she needs to go to the stomatology department and undergo surgery to correct the problem in time. However, if the correction time is late and the child’s speech habit has been formed, it is also necessary to carry out rehabilitation exercises for speech function.
