Children with autism often exist in their own world where they are unable to successfully communicate and interact with others. Also, children with autism may have trouble communicating nonverbally. For example, trouble communicating with hand gestures, eye contact and facial expressions (2012).

Not every child with autism will have a language problem. The ability for a child to communicate with autism will vary, depending upon their intellectual and social development. Some children who have autism may not be able to speak. Other children with autism will have large vocabularies and be able talk about a specific topic in great detail. Also, most children will have no problem pronouncing words. The majority of children with autism will have difficulty using language effectively. A child will have a problem with the meaning and rhythm of words and sentences (2012).
