My DS2 is just finishing Y3. He has some SN's, and due to development delay has a few issues as he is not often playing the sane games as his peers.
He is quite old for Y3, he will turn 9yo just 7 weeks into Y4. He is very quiet, and doesn't speak out about things that happen to him.
Yesterday, my Ex picked him up from school, and was told that there had been an 'incident' that meant that DS2 had had to have his clothes changed. He wasn't told much else.
On arrival home, DS2 was behaving very uncharacteristically. Rather than stay in the front room with everyone (he doesn't like being alone, part of his SN's), he took himself off to his room and say quietly in there for hours. He wouldn't talk to me about what happened.
