If you have concerns about your child’s development and behavior, your child should be seen to tell if she needs therapy. You do not need a diagnosis of autism spectrum disorder (ASD) to begin many kinds of therapy. There can be a long wait for ASD diagnosis, so it is important to start therapy while your child is still waiting for a diagnosis. However, once your child is diagnosed with ASD, she may be able to get more interventions, such as applied behavioral analysis (ABA). It is important to have your child seen by an ASD specialist even if your child is already receiving intervention.
