If your baby’s speech is not clear, consider the following. Short tongue tie: such a child’s speech function is not clear, but there is no problem with language organization, he is able to clearly describe the logical ability of a thing, but he is not clear with certain words. It is necessary to go to the stomatology department to confirm the diagnosis and then cut the tongue tie for the child, and it is best to deal with this matter around one year old to prevent the child’s speech from being unclear and getting more and more serious. Delayed language development: the child’s ability to organize language is not strong, or even a single word description can not be hyphenated into a sentence, this case is considered to be delayed development of language function, we need to diagnose the child clearly, and then carry on the rehabilitation of language function exercise. Autism: children with mental retardation have poor language function development, so in addition to poor language function, physical communication also can not, can only stereotypically describe something, we must give the child a cranial magnetic resonance electroencephalogram and intelligence test, and autism assessment test after the diagnosis of autism need to be given to the child with the rehabilitation exercise and the family’s care, so as to let the child step by step out of the plague of autism. The child’s lack of clarity of speech must be corrected in a timely manner, within three years of age, the most appropriate stage of development of language function, in order to allow the child to better develop in the future during the process of language development.
