Starting work with your childIf you even suspect your child has Autism or ASD, you must begin work with him immediately. Do not waste vital time waiting for a formal Autism diagnosis. I met one mother who waited six months for a formal Autism diagnosis before beginning any treatment. Imagine how much she could have taught her child in that time. You will find out for yourself that most doctors know very little about Autism and will simply recommend speech therapy, special education or an early intervention center. The worst thing some doctors will do to a parent is to take away hope. You will acquire more information on Autism from other parents of children with Autism than you would from any general practitioner. As you work with your child and see the results, you will soon find other parents of newly-diagnosed children with Autism coming to you for advice. Start working with your child now, even if it means just trying to communicate with him through play. This time will never ever be wasted.

Classes were offered for staff, parents, and the community, educating them on how kids are using technology and how they can talk to them. They saw immediate results; student postings online were suddenly more appropriate, teachers proactively worked to prevent misuse of technology, and parents and adults from the community attended classes and began discussing technology use with their children.
