My youngest is so explosive and violent when he doesn't get what he wants or is made to move away from something he's doing or taken to nap etc etc.
He hits, pinches scratches and screams and screams. It's starting to get me down now and I don't know what I'm supposed to be doing about it, he's too young for time out/naughty step type thing. We've tried consistently telling him no, tried ignoring completely. Nothing works and he's getting worse Today for picking him to up to go for his nap I gained theses lovely new wounds 
What should I be doing? Is this normal behaviour!? He's my fourth but none of the others were anything like this, I'm feeling useless and at a total loss.
