Will someone please tell me how to deal with my 11 yo boy twins and the constant arguing, fighting, bickering and punch ups. I mean really it's constant. They can't be left in a room with one another for 5 minutes without an argument or a fight breaking out. And it's making me feel ill. It makes no difference what sanctions I bring down or whether I beg and plead or ask nicely or scream like a lunatic. Sometimes I cry and they nod sagely and say, yes Mum we'll stop. And literally 10 mins later they start again. I despair.
