Unfortunately, I don't really have much in the way of advice but can tell you that in looking back, I don't see how my parents lived in the same house with me and my older sister. We fought EVERY day from breakfast until bedtime. sometimes even got physical. I think it's just what siblings do. I know that my daughter got very tired of her boys fighting all the time so she tied them together so they would have to learn to work together. They had to walk together, go to the bathroom together, do everything together and it did teach them to cooperate with each other. I also think that instead of finding things for them to do together, maybe you should suggest that they find things to do separately. Not only will it keep them apart (so no fighting) but will also give them separate adventures and something to talk about. Good luck!
