Identical 9yo twins that "hate" each other
We have identical 9yo twin girls. They can have fun together but currently it seems they really are taking a disliking to each other. Things we used to be able to do with both of them at the same time are no longer possible, they detest each other's company and will bully each other and fight.
We realized that we've optimized for efficiency, so they attend same school (different classes), they share a room and a large bed, they get baths together, they attend the same things. That we can control and change at the cost of some overhead in how we live our lives. But outside that, any tips from parents in similar situations much welcome, what's ahead?
