DS is nearly 8 and in Y3, he's one of those calm quiet(ish) kids who constantly analyses stuff and overthinks everything. He gets anxious about large groups (but not every time), he's a bookworm and science fan. Quite geeky 
Anyway, he's been having tummy aches for nearly a year now, doesn't want to go to school because "he's tummy hurts there all day" and "everyone keeps talking at lesson time" (when people interrupt and don't follow the rules, he gets stressed about it). School is being lovely and supportive, moved tables so DS doesn't have to sit next to chatty kids. No bullying and he has couple of very good friends.
Most mornings he wakes up with tummy pain and most nights he goes to bed same. Btw, we have ruled out everything medical with loads of tests. And also not in pain during weekends and just had two weeks pain-free Easter hols.
I hate seeing him like that. I have thought about HS, lurking here a lot and general googling. Tonight DS came out of bed again for 100th time asking if he has to go to school tomorrow
So I just said to him what if I said he doesn't have to go back. His face lit up! We talked about it more - he feels he wouldn't want to leave his friends but he would like to spend his days with me exploring outdoors and researching cool stuff, doing any maths he likes
not "boring school maths he already knows". We agreed to think about it more and not chat about it at 10pm.
I haven't joined any local HS Facebook groups but would it be OK for non-HS coming along to any meetups for a chat? Do you think this would be best way for me and DS get an idea what HS is about? Any suggestions or anything to consider before making the decision? Or to help to make the decision?
