Who Uses Sign Language? | verywellhealth
It is not just deaf and hard of hearing children who use sign language. Another large segment of sign language users is hearing nonverbal children who are nonverbal due to conditions such as down syndrome, autism, cerebral palsy, trauma, and brain disorders or speech disorders. For parents, sign language provides a means of quick communication, particularly for those whose attention spans may be very short or language very limited. Or it may be a tool for language development prior to developing spoken language. For children, it is a means of expressing themselves so that they are less frustrated.
