Where do people live that an ASD diagnosis appointments are available just like that?
Took two years following an urgent referral from paed here. And that's after the initial referral to the paed, and the delay for that too.
Early trauma isn't an excuse for poor behaviour? Nice that you can contain things so easily.
Early trauma can damage a child in a huge number of ways, one of which is that the "fight or flight" drive stays on hyper alert all the time. Couple that with possible autism, and you have a fairly explosive child, who can find ordinary every day stimulus overwhelming.
Given that colouring in has been agreed by the teacher, it sounds as though there is already a support plan in place; I highly doubt this is the first conversation op has had with the school.
So what I'd see here is child getting overwhelmed, escapes into colouring because that calms him down. Starting to lower defences. And is then abruptly interrupted by someone intruding into his private space and demanding his full attention immediately.
It doesn't actually matter at that point whether she was shouting or using a very firm no-nonsense voice. His perception was that his calm space was suddenly shattered, and he reacted to it. Her breath may not have smelt bad bad, but it probably smelt of breath, which is an additional sensory intrusion on a child already experience sensory overload.
Yes, I think exclusion is overkill here. Of course he shouldn't have sworn at her. But it sounds to me as though she is quite "old school" and thinks he should just pull his socks up and get over it, that letting him colour in in the first place is pandering to him when he should just behave. A better approach would have been to give him a couple of minutes, or to gently remind him it was time to move on. Not because children shouldn't be disciplined, but because this is a child with a particularly difficult set of circumstances, and a mainstream classroom can be an unbearably overwhelming space at those times.
Op I've known some children have a series of cards which they can hold and put out on their desk as a signal to the teacher. Yellow would be "I'm finding this difficult" and red would be "I need to leave the classroom now for a bit."
Would something like that help prevent the overload?
