Hi, have two dc aged 12(m) and 10(f). both strong-willed, extrovert, want to be in charge. They fight like cat and dog. They have fallen into a fairly destructive pattern of argument in which dd winds up ds, will not stop, ds ends up hitting her, she screams blue murder excessively loudly so others can hear and he gets a bollocking from his Dad, which makes him feel awful, and blame her, etc etc.
I know this is common, but people in other families have commented on how much they argue. Anyone got any tips for mediating a happy home?
