I feel like I am failing as a parent right now. My 8 year old son has turned into an absolute nightmare. His attitude and the way he speaks to me is awful. It is constantly "I hate you" and "your stupid" amongst other things everytime is he asked to do something he doesn't want to do. I've tried being consistent.. firm but fair but then ended up just shouting at him and that doesn't work. If I threaten to take away electronics he just shrugs and says "well I don't care" and that infuriates me even more. Its constantly eye rolls and strop and I feel like I'm having to walk on egg shells around him. Is this normal in an 8 year old? How do I even get through to him.
