My son is nearly 4 now. At 3 he had about 6 words and four of them were types of vehicles!! That was the time of his diagnosis.
If you don't have faith in the schools, can you get ABA afterschool in the form of home tuition?
I didn't realise my son was different at all. His total lack of speech was picked up on at 18 month check. He didn't meet any of his milestones. HOw did I miss that? I made excuses for him. I thought he was 'a typical boy', he was strong-willed, he would develop in his own time, he wasn't very obliging. Sounds like denial now. THe number one thing I noticed about him was that he wasn't a happy little boy. He seemed to be permananetly on the brink of a huge tantrum or getting upset over nothing.
In the last year his speech has come on brilliantly. It's still behind, at nearly four he still says "me hungry now' but wow this is progress. Last year he would just point to the bread bin!
I didn't get to choose a school. He's going to do two years at an autism pre-school and start mainstream school a year later than normal, but I'm in Ireland so not best person to talk to about 'the system'! but just giving you a pat on the back really. The days and weeks after dx can be a bit bleak. I wondered, when I wallowed, if my son would be eating sandwiches in some crappy bedsit on his own on christmas day after I died.
I know you must have so much to take in right now, but although I could hardly tell you what ABA is, I'm so very impressed with the progress the 'team' have made with my son. Bunch of blonde psychology grads, all very trendy, don't look like they have more on their mind than boys and clothes tbh, but they know what they're doing!
