My 9 year old son was diagnosed with ASD in July last year. Due to ongoing difficulties between him and my 6 year old daughter, amongst other reasons, we have an appointment tomorrow where CAMHS will help us explain the situation to them and what exactly autism is and how it affects people. He is asking the odd thing where he says knows he is different and my daughter is wondering why he gets away with things she doesn't. She is awfully sore on him and he is now overreacting to situations where she annoys him. I'm scared tondo this as realise once we have told him there is no going back. Anyone any thoughts on this or can tell me how it affected their child when told?
