Children with autism must work harder to have skills that others have. The best time to begin speech therapy is after your child has been diagnosed with autism. Speech therapy is does not only focus on working on your child’s speaking skills but also their ability to use language to communicate effectively and express what they want to say or show. Communicating without much trouble is what speech therapy aims to achieve. Speech therapy also helps an individual’s ability to read and understand facial expressions, body language, tone, and cues from others – both verbal and non-verbal.
