My ds (7 almost 8) has Autism. He didn't start talking until he was 3 1/2 and he was discharged from SALT just before he was 6.
He is in Mainstream school, and not needing 1:1.
He is quite an anxious child. He is incredibly affectionate and so happy. He has friends, but he can find it hard to play with them, but he is also happy enough skipping around on his own, it took me a while to not feel heartbroken about him playing on his own at school.
I have ds2 (3) and ds1 is the best brother. He watches out for him, plays with him and is incredibly patient with him. In fact i think DS2 has helped DS1 learn how to play imaginatively...i see ds1 watching him :)
The only time he has hurt someone was at school in year R, a new child had started and they were only allowed a certain number of children in role play area...DS didn't know how to communicate this to the child (who was trying to join in) and being an unfamiliar child as well, DS bit him. Didn't mark him, and ds infact went and told the teacher himself.
He amazingly potty trained himself at 2 1/2 ... i wasn't ready for it if i'm honest!
He loves cuddles, tight ones, i think it's the pressure he likes. You can usually find him under a blanket...even on hot days.
It made me laugh, at the dentist yesterday ds2 was just skipping around the room and playing around, and ds1 said "Mum, why is he so bonkers and won't sit still".... i just said to him, if that had been you at that age you would have been running out of the door and long gone!! Now, he fidgets ALOT and hates waiting. But will sit in his seat (in a variety of positions).
It's always a worry how life is going to treat him, but he really is happy. Teachers at school just comment on how happy he is all the time.
This is my experience. We just take each day as it comes :)
We are also going through SALT with DS2, he is a big mixed bag who is confusing the professionals.
