Love to get your thoughts on this - my nephew is 7 and for the last year or so has turned from a delightful, polite little boy in a surly, rude monster. He has no respect for anyone and barely talks now, except to moan about things. He no longer eats with a knife and fork, instead uses his fingers and then defiantly wipes his hands on the furniture, he refuses to answer even the most simple questions eg. 'would you like a drink?' is greeted with a sulky look and a stare, and is even soiling his pants now and when asked by his mother why he did this he said 'that's what I do'!! He is a bright boy but is becoming very disruptive at school now too. My parents now refuse to have him in their house as they can't tolerate his bad behaviour and we are all very worried that he'll just get worse. Poor lad sounds pretty unhappy, but we've tried everything to find out what might be wrong. Anyone else been through this?
