Sorry - I seem to be clogging up this board a bit atm!
DS2 has definitely found his 'angry voice' recently and has squeezed our arms and pushed his mouth against our cheeks a few times, but this is the first time it's ever been directed against someone outside the family. It was at the end of school;the TA had turned round to pack his bag and didn't see what led up to it. The girl he bit is his 'best friend' - she's lovely with him but tends to the maternally bossy at times and doesn't always read DS2's 'give me space' signals. It could have been this that triggered it, or the fact that our respite worker was picking him up and I'd forgotten to tell him (for the first time). The biting incident happened just after he was told she was getting him, not me.
So, how do we handle this one then? The Mum was lovely about it apparently and I'll see her and apologise tomorrow. DS2 has also said 'sorry' by which I mean he repeated the word after his TA, but I think it's important for the other children that he did so. But how can I teach DS2 to express his anger appropriately, when he has a limited single word vocab and doesn't use it creatively - by which I mean he can't just summon up a word or phrase spontaneously, it has to be taught?
