Sibling rivalry

It seems as though all my younger children do is bicker and make one another miserable. This in turn makes me furious and toting a headache the size of Mt St. Helen's. I read various children's articles that say this common. I try to count to 3 even 10 when it seems like my head s going to explode. But I found myself filled with anxiety. The cure? I enrolled them in daycare!
