Hi i have tried everything in the book over 3 years and i just dont know what to do about his behaviour. He is nearly 5 now and he still hits me, bites me, punches me and also kicks me aswell as throw things at me and break things to upset me. I have tried nearly everything and its come to the point where i have had to restrain him so he doesnt hurt either one of us and it kills me inside. What do i do?
