Iamthinking what's happened with the bullying. Did you send the letter in in the end?
Muddling well done your ds. Ds2 has been round to a friends to do homework after school, but hasn't ventured out on his own anywhere yet.
DeeDee it is really hard when they go somewhere different than their friends. That was what happened to me, on top of which we were out of catchment and lived a long way away from everyone else that went to my school. It did take me longer to settle than other pupils that already had friends there, but I made friends with a little group about half way through year 1 (now year 7 - I am ancient [blush) and we remained friends from then right through college and in some cases longer, so hopefully it will get better for your dd.
The fact she comes home happier than she goes out sounds hopeful, like it's more the idea of school that's daunting, rather than the reality. Hope she settles in soon.
smellylittleorange poor dd. I think ds2 felt a bit like that after he came with me to collect dd from his old primary a few weeks into term. It's that yearning for the comfort of familiarity. I told him I understood, but that while primary will always be a fond memory for him, before long secondary will just become his new normal and he'll be able to look back at the memory, without wishing he was still there. Hope your dd is able to settle and enjoy secondary more soon.
balletgirl your ds sounds like he is doing fantastically and the school sounds really supportive too, which is half the battle. Ds1 (also ASD) tended to make friends with older pupils too when he first started, but has gradually made more friends in his own year as time has gone on. He's in Y9 now and seems to have friends in just about every year group, right through sixth form - not bad for the quirky kid who only had one friend at primary. I do think indie's with small class size, if properly managed, can really help facilitate social inclusion - they have vertical tutor groups at ds' school as well, which also helps.
shebird I haven't noticed any major problems, yet, but I have noticed a shift in ds2's friendships slightly. He's made a few new friends that weren't at his primary school and his closest friends from primary seem to be doing things without him. That said, I know he's chosen to specifically befriend and look out for a couple of the less popular, more quirky lads, as he hates to see anyone excluded - he did the same at primary.
I suspect he's a bit sad about his primary best friend seemingly moving on and becoming closer with another boy from their old primary class - but we were already aware of there being some parental involvement in pushing these lads together, as the parents have become good friends themselves and sadly for ds2, we are just not the right sort of family for them. I think it's also been exacerbated by ds being a good upper/average pupil and the other lads concerned both being in the top of the top groups, so in addition to the other two seeing each other regularly outside of school with their parents, they are in the same sets. I need to check with him tonight, because I suspect he might be walking on his own - at least in the mornings, although he had a lift today, as he was lugging yet another 'project' homework creation. 
He was so tired by half term that all he wanted to do was chill out. We had one day out, that involved a lot of walking, but other than that he didn't really do much. As a result the walking yesterday really knocked him for six and he was on his last legs by the time he arrived home. It's gob-smacking just how quickly he deconditions. I'm fully expecting him to need pain relief by the end of this week.
