Stuttering is the repetition of a single word in the speech process or the presence of a spitting disorder, etc. It is not a genetic disorder, and stuttering is not usually passed on to children. However, stuttering is a learned habit, and some people who stutter do not really have an organic lesion, but simply have a habit of speaking in a manner or repetition of speech that has formed a habit. It is possible that living with a person who stutters frequently or constantly imitates the stuttering behavior, resulting in habitual repetition of speech and consequent stuttering. Therefore, stuttering is not a genetic disease and there is no need to worry about genetic problems in particular. However, when children have stuttering symptoms, they must be checked for diseases of the ear, tongue, mouth and throat.
