As psychological and physiological development and circumstances vary considerably, the problems of speech and language in children are further complicated. The speech therapists (ST) who have been concerned with these children and their families are requested eagerly to reconsider and control their own communicative attitude. Furthermore, STs have to improve clinical technique that is appropriate to each child. In this report, the author shows the outline of the speech and language problems of children, and discusses the merit and demerit of speech therapy itself. The clinical approach for motor speech disturbance and sensory language disorder is also described.
