How do you stop children from fighting with each other all the time? Mine drive me crazy most days with the squabbling!

It's part and parcel (and I feel, half the fun) of having siblings because no matter how much we argue or fight, we will always be bonded by blood and love. We used to drive my mother crazy too with all our squabbles and what my mom would do is to "threaten" to send one of us away to live with a grandparent or some imaginary relative in a faraway land since we didn't appreciate each other and insist on fighting. Despite the squabbles, the thought of being separated from one another was enough to quell the fighting for a day or two.
