DT1 quietly 'winds' DT2 up, DT is very 'verbal' and is becoming quite cocky. They say horrible things to each other, mornings are a nightmare. I've tried separate bedrooms, bedrooms together, they're in seperate classes, have own friends etc. They wouldn't dream of behaving the way they do with each other with their own friends. I'm at a loss of what to do... Does anyone else have the same problem?
