clementineorange I'm with Reality on this one. My eldest is Autistic and my youngest (of three) going through diagnosis.
Autism is never an excuse in our house but it is sometimes a reason. Because my son is Autistic if lots of little factors have added to his stress factors for a day there are occassion's when there's just no point trying to keep teaching because he's at melting point. He gets to melting point as part of his Autism. He's not opting out as a naughty child. It's recognising that for that session, productive learning isn't going to happen. It's accepting that as part of his Autism sometimes he needs to step away and destress. It is part of mindfulness.
Fortunately, he's phenomenally academically bright and can absorb information at a far faster rate that just about anyone I've ever met so catching up is never an issue.
My son is very popular, elected class rep, gets nominated and wins lots of prizes for outstanding achievements etc - he doesn't however, seek company and likes to be on his own. He knows how to play many games and will politely go through the motions but doesn't appear to get any pleasure, it just mildly adds to his stress. Being on his own doesn't mean having a tablet or PC strapped to him either. He needs to know how to interact, something that he is capable of but we can't teach him pleasure in that interaction - just tolerance of it and the logic behind/ necessity of human interactions.
I agree with the sentiment that Autism shouldn't be seen as an excuse and very strongly that we shouldn't allow it to restrict our aspirations and expectations for our DC but the hard truth is the path to achieving those aspirations is a tougher one with Autism. Sometimes it's about picking which battles to fight.
Regarding little Johny is still in nappies but it's okay he's happy. It may well be that his bowels are immature and that actually it's not that unusual for ASD school age children to still be in nappies. My own son has a whole myriad of parallel diagnosis alongside his Autism, including physical issues - I don't real off his diagnosis if something needs to be said I use the catch all diagnosis of Autism.
It may be that he is just coping with finding his feet in a new class setting having been through the stressful diagnosis process. It may be that he's on meds for ADHD and sleep and the battle to settle med levels are being fought first before creating a new stress. It may be that someone tried to force him to toilet train before he was physically capable because they didn't want him to be different and its caused a significant psychological issue that will take a long time to unwind.
Tolerance of the whole range of abilities within the ASD spectrum is important. There isn't a magic cure. It's wonderful that people find things that work for them and their child/ mindees but one solution will not fit all.
You sound like you want what is best but please remember many of us are wading through the minefield trying to achieve that too.
