My kids started the day as they do most every other: with a fight.
I have a sibling and we bickered. We also knew we were in charge of working through our disagreement. Being able to sort out who gets the blue-handled scissors is first - and for how long - is no small feat in this household. But my rule is if I have to intervene, the object of the fight is mine. Works pretty well to maintain squabbles.
My goal isn't to end up with 15 or 20 odd toys tucked onto the top shelf of my closet by day's end. I want my kids to understand how to work through their own problems. I'm hoping they learn to work it out before my shelf breaks.
