I wrote about his scratching a few weeks ago. Yesterday I tried to help him not spill his milk down himself. He evidently thought I was taking it and scratched me hard in the face. No warning, he was completely calm a moment before.
He's started having episodes of destroying anything he can reach, running round pulling anything he can off surfaces. He goes for his brother several times a day. He's very stressed by everything. He's picking up how very down I am about his behaviour.
Please - I need a simple, consistent and effective reaction. I'm swinging between disinterested (which involves people getting hurt, possessions being damaged) and shouting. Which does nothing except make him redouble his efforts. Time out seems to really upset him and he's in danger of hurting himself. I feel useless.
