DS is 7 yo and has been diagnosed at 4 with ADHD. Struggles to listen and sit down etc but nothing horrific like you see on TV. School have been amazing - he has special funding for individual help in the mornings etc and they go out of their way to support and care as well as involving us. Problem is that since going into Y3 when it gets much more intense, his behaviour has deteriorated. He refuses to do things regularly, is becoming rude and defiant (his massive strength has always been how kind and sweet he is) and says really stupid things to his teachers like he wants to kill himself/get expelled etc (very confident he doesn't actually mean this). He also bites his arm and bangs his head with his palm when he gets things wrong in class (again, I really don't think this hurts him in the slightest but it can be quite unsettling to watch). We have now received an email from the head saying his behaviour is becoming increasingly problematic, they want various meetings to discuss and consider further local authority input. Really scared they want to send him to a special school away from home and friends. I think he might be dyslexic and this is being missed - everything is being lumped into an ADHD box and no other explanations being sought. Not really sure what to do. Just know that a crap decision at this point could ruin his whole life. He's a precious and lovely boy, just bloody hard work at the moment. I don't want to fail him. He's relying on us to make the right decisons about his whole life and I don't know what they are.
