They fight over everything and anything. The fights get very physical. I am at that point where I have no idea what to do but I have really had enough of it (apart from the noise and emotional distress it causes me things are getting damaged and broken during their fights and I am worried about their safety). I want them to learn to resolve their issues with each other but they are both so hard headed that neither will give in. Can anyone give me any tried and tested tips to help. x
