My 4 yr old son has been behaving quite strangely in the past month. He cannot control his emotions, loses temper very easily, often gets angry and shouts at everybody, doesn't want to sleep (actually always complaining he cannot sleep), throws things around and is a bit violent towards the maid, his baby brother and sometimes mum & dad as well. Just now, my maid told me that he threw all his food on the floor with no reason.
I really don't know what's wrong and what I can do. Sometimes he just behaved so badly that it made me lose temper myself and shout back at him. Tow nights ago, I even locked him out of the house (which I know is something very wrong to do)!
I'm so worried now. Can anyone offer any advice?
