Daily Drag-Fighting children

I Googled images for 'fighting children' and this strange image came up. What is going on here? Looks like an angel saving a child from the devil? Hmmm, wish I could say the same about myself! I've got two she-devil for children right now, who won't stop fighting. And I'm so tempted to let them duke it out. The problem is they are a lot bigger than I am so if I do have to intervene, I may just be the one who ends up with a black eye. I think this is a phase (I hope I hope) but if it's not I may have several more years of the back and forth. I'm supposed to know how to 'facilitate' conflict resolution??? I'm not doing such a fantastic job of it in my own house. Help.
