My dcs (aged 9-13) ALL bicker ALL the time.
The eldest talks to her younger siblings in a tone of voice that says "idiot", her reasoning is that the younger ones don't speak nicely to her.
I have tried to reason with her and explain that she is older and should know better and that the younger ones don't mean to ask (according to eldest) questions or make comments in a way that she is not happy with.
In short - they are all driving me mad!!!!!!!!!
I have tried to talk to them all about it, I have balled and shouted at them too....no better.
any tips?
