I ended up exchanging a few messages with his TA last night. She acknowledged that detentions don't work for him and won't be sending him to any more. But then he will be with different staff in September ...so will this start again (given school's behaviour management strategies). Ugghhh
But I am saddened by DS's behaviour. He has been upsetting his classmates by saying mean things. I don't know what exactly what he frequently tells me that I am ugly, fat, stupid etc. This did seem to be only directed at me or occasionally DD. It has reduced a lot at home since I adopted a strategy of never reacting to it in the moment (I had previously tried that but was less consistent).
Sorry about the friendship thing @Carrie. My friends' children are generally a lot older than mine (other than Mum friends with SEN kids) so it does not really lead to those kind of comparisons - and it is really hard not to.
Looking forward to watching the film that you recommended @openupmyeagereyes
