LOVE EM OR LEAVE EM

My girls are close in age, 2 years apart and I wonder if that is why the seem to fight so much. They love each other, I don't doubt that because they have many moments of sweetness and love.... BUT I regularly break up what feels like dozens of fights every week. They are usually scraps over little, insignificant things, like toys, stuff really.
Am I the only Mom tired of the fighting? The only one who wants to scream at the top of her lungs....ENOUGH ALREADY!!!!!!
