I thought if anyone can help, MN can so here is an excerpt of a message I just posted to my sister, who's also a teacher:
"X is a real worry. His "behavioral issues" started up again with a venegence once he got back to school. On Friday he hit his beloved friend Vicky and pushed some other little girls down. He shouted at his teacher & wouldn't share the classroom toy garage. His teacher is sympathetic - I have the impression she really loves X - but she said she's tried all the various disciplinary techniques that she knows, both as a teacher & a mother and nothing works with him. She told me she needs some outside professional support because she can't cope with X and the 19 other 4 yr olds in her class. I'm desperately worried now. I've spoken to several pedopsychiatrists in the area & they are fully booked for months."
Does anyone have any advice? Thanks. I'm frightened, tbh.
