About 9 months ago we followed the recommendation of our son's school and started the process of having him assessed for Asperger's ? partly because he was getting unsympathetic treatment from others - from some kids, bullying/teasing, and some adults also, jumping to conclusions about the way he talks and acts. We have just been given a diagnosis ? "High Functioning Autism" ? and are thinking through how to talk to him about it, and how to discuss it with his older sister. He is 10, his sister is 11. They both know he's "different" but we haven't used labels so far. Does anyone have any advice on ways of breaking the news, beginning to explain? Did anything work specially well for you, as a starting point? Was there anything that turned out not to be so helpful?
