My three year old has started to physically attack me, this is something that has progressively gotten worse, now he is attacking me every time he is reprimanded. He even attacked me whilst driving which was extremely dangerous. We don't expose him to any violence and have never hit him (not even tap on the back of hand). He is just always so angry and shouts constantly at me. I'm at a real loss at what to do, any tips/advice?
