Please help me. My DS is 7-years old and is incapable of doing as he's asked/told. After yet another disastrous bed time I am literally at the end of my tether. My DS can be the most loving, funny, charming child in the world, but much more frequently he is disobediant, disrespectful and just down right naughty. It's very much if I say black he says white. He's OK right up to the point he's told 'no' at which point all hell breaks loose. I've tried it all, talking clamly, shouting, reward charts, taking away favourite items, giving treats, with-holding treats, time-out, ignoring and nothing seems to work. I just don't know what to do any more and believe this is damaging our relationship. I now dread weekends and school holidays as I know the majority of the time will be spent in battle. My DS has a twin sister and I am a single parent who feels she is letting her children down. Can anyone help me with coping strategies and advice?
