Speech / Language Therapist: A speech and language therapist helps develop better control of the jaw and mouth muscles, which can improve speech and language skills and eating abilities of children with cerebral palsy. They also help develop creative communication methods for those who can not speak. A speech and language therapist will work with your child on communication skills. This means talking, using sign language, or using a communication aid. Children who are able to talk may work with a speech therapist on making their speech clearer, or on building their language skills by learning new words, learning to speak in sentences, or improving their listening skills. Children who can not talk may learn sign language, or how to use special equipment such as a computer that actually talks for them.
