My 2.5 yr old boy is unbearably bossy (at least with me, not at all with friends). He'll drop things and demand I pick them up ( I don't, at least not generally, unless they're creating a hazard). He demands I play cars with him, but then he shouts at me for doing it wrong. He is always telling me off saying "no mummy". He has even done that when he has just turned a corner and seen me and I'm just standing there! If I don't understand something he's saying, he explodes at me. I feel like I'm a punch bag waiting to be battered (emotionally). Has anyone else had similar, got through it, and perhaps any advice?
