Posting here as little traffic on SN chat.
I know Asperger's isn't a used term now but that's kind of the level I'm talking about - autism which needs little external support. Is this often missed until older? When is it picked up by people other than the mum?
DS is just about to turn 5, I see various signs but I seem to be the only one. He's a clever little boy, probably a year ahead in reading and maths without any pushing from us. He struggles with lack of certainty, making decisions, time (is anxious about how long everything takes), has word final disfluency and uses very grown up language and old fashioned phrases. No specific special interests (enjoys board games, Lego and STEM activity sets), seems to have friends.
School are not worried, DH doesn't see it, grandparents don't see it.
Is high functioning autism often missed until they get older?
