just a quick note gotta run:
DS4's paed Dx him at 3.10 after 2 sessions of meeting him but i was convinced he has aspergers, but its really NOT apparent to school at all.
DS5's paed wont diagnose at all, and hes been seeing him now since he was 3mths old (first was faultering growth, then developemental issues by 18mth), DS5 is now 3.2y and its glaringly obvious that he does have autism (quite severe), with ALL the usual symptoms and history (ie regression at a year old). but still no Dx other than GDD.
So one child with symptoms that only some see and a Dx. The other child with slap-yer-face symptoms and no Dx. It seems that it depends entirely on pot luck who you work with.
I knew by 18mth that DS5 is autismic (whoever gave us that phrase, thanks!!!) and I think that makes a HUGE difference. wether or not you know whats going on. wether or not the school, paed, or uncle Tom knows, doesnt matter, mentally speaking, its us that counts.
so i understand your frustration. My feeling is, that if you have researched (and i bet you've done hours of it, like the rest of us) and you think your DS has ASD, then he probably does.
The next step is: knowing this information, what can you do to help? I personally feel that when you know WHY a person is the way they are, then its easier to accept their differences and be more understanding (note i didnt say have more patiance!). good luck, have faith in yourself, you are a fantastic mum. xxx
