oh hun don't push the TT. Kids on the spectrum are notoriously late TT'ers. Often times they don't feel the need, so its a physiological thing.... if it isn't working, try again another day When he gets it, he will get it

Have you started anything to help him? I remember with Matilda, at 2 1/2 we hadn't even had autism cross our minds... I mean autism means sitting in the corner rocking right? I didn't know that my child who was extremely frustrated with life. Try finding his triggers and figure out if you can avoid them for now, os what you can do to help. Try rewarding him when he's behaving good. I mean even when it seems silly, but Matilda used to get a tick tac for every isle we got through at the shops without screaming... it worked for most of the shop... than she got a chuppa chup at the check out so I could get through. I had to bribe her into good behaviour just so I could get through the shops without screaming, than we would get home and she would scream for 3 hours to de-stimulate.

I had to become a robot for her to tell her what was happening every morning, no surprises etc etc. Now that we know what she has, it all makes sense.... But she's 5 now... and it sucks and is hard, but a lot easier than it was.
