[quote Justsawagecko]@33feethighandrising Thanks so much, your post made me feel a bit emotional, what is the wandering off thing do you think? She fire it less now, but can still go off exploring where she’s not supposed to and when younger, would just walk for miles with me following her! She’s amazing, but I’m exhausted pretty much all the time. Her peers seem more chilled or something. She doesn’t seem to have any problems with socialising though and will just walk up to anyone and say hello, which I was pleased about as I was very shy as a child.[/quote]
I'm not sure, we never really sussed it! He did love to run off though, and he loved to explore. I had friends who could take their toddlers with them for a Sunday lunch in a pub and they'd happily sit in a chair 
DS? No way! He'd want to run behind the bar, get in every room (in a pub there are often lots of rooms you're not allowed in!) It was like he wasn't happy till he'd explored everywhere. (We gave up on the idea of Sunday lunch in pubs).
Or, if we were outside, he'd just run and run all over the place, he didn't seem to be heading for anywhere specific. And he didn't look back!
I was exhausted all the time when he was little. I remember when he was small talking about how tiring a day was, and how hard it was to get stuff done and getting roasted by other posters here as they were like "WTF are you on about, you've hardly done anything, that's a normal day", but keeping up with DS was exhausting! I didn't know he had ASD then.
DS calming down coincided with him having enough complex language to have a conversation with us that he found interesting. Mostly about imaginary worlds. And I wonder if these things are connected. It was like he suddenly noticed we could actually be of interest to him! He must have been about 4 I think.
DS is unfazed by other children. Some DC have tried to bully him in secondary and it's like water off a duck's back, it just doesn't get to him because his logical brain says they're being ridiculous, so why should he pay any attention to them? I wish I could be so matter of fact about it!
But he does find large groups difficult. We've not done any parties since his 8th birthday, which was something he looked forward to for weeks, then spent most of the party hiding under the table or outside, crying. It was just all too overwhelming I think.
He found it hard to make friends in primary, he had one DC he saw as a friend - although his teachers told me he did spend time with other DC too. In secondary, he's started finding his "tribe" (other geeks!) and he's making friends which is great to see. I've always said to him that the interests he has are ones that older DC tend to like, and his age group will catch up eventually, and it looks like it's starting to happen.
