Parents of children with autism suggest that something is wrong with their child when the child is 18 months old and look for support when the child is 2 years old. Autistic children typically have difficulties in verbal and nonverbal communication, social interaction and imaginative play. Some also show aggression towards other people or even themselves, have repetitive body movements, unusual preferences, difficulties in adopting change, aggression towards fast moving things or things out of routine. Some people with autism are sensitive in the range of the senses (sight, hearing, touch / feeling, smell and taste).
