When I was a kid, my brother and I used to fight about everything. My mom would alway step in and settle our fights. She'd set the timer when we were fighting over a toy or she'd listen for as long as it took to hear both sides of our story about who started it.

I started to do that with my own kids, now seven and four, until it drove me almost to the point of madness.  I admit, I'm not nearly as patient as my mom is, but I started to realize that my kids were fighting all the time just to get attention from me. 

I decided that I was going to try to have siblings without rivalry! My plan was to simply stop involving myself in their fights. Now, as soon as they start to fight or bicker, I walk them right down to their room and tell them that they can come back out as soon as they "work it out." I've noticed that when mom isn't around to play referee, they work out amazing solutions to their disagreements in just a few minutes.

Lately, as soon as they start to fight and I say, "Head to your room to work it out," they smile and say, "We worked it out, mom" and then start whispering to each other to avoid having to do to their rooms.

If you have kids that bicker nonstop, try taking yourself out of the equation and using the "siblings without rivalry" technique. You may be surprised at the agreements that they come up with! 

Just a disclaimer, my kids don't physically fight, they just bicker. This may not be the best option for kids who are prone to throwing punches!
