Four words that tell you whether to break up a fight

Two grown adults sat on the floor of a parent workshop, one pretending to be an eight-year-old boy building a zoo out of blocks and toy animals, the other playing his little sister who wanders over and announces, 'I wanna play too.' Within a minute the 'brother' was prying the sister's fingers open to get back a plastic zebra, and the 'sister' was wailing for their mother.

Adele Faber, running the group, asked the parents watching what they'd normally do. The answers came fast, run in and stop it, take the toys away and send both to their rooms, tell them they're acting like animals, figure out who started it and take that side. One at a time, parents tried these exact lines on the 'fighting children,' who reported back how each one actually felt to receive, standing there in role. Nearly every standard response, it turned out, left the 'children' feeling more cornered, not less.

What worked was slower and less satisfying to say. Acknowledge that they sound angry at each other. Reflect each side's point of view without picking one. Name the problem as genuinely hard, two kids, one toy. Say plainly that you have confidence they can work out something fair to both of them. Then leave the room.

That sequence maps onto what Faber and Mazlish call the levels of a fight. Ordinary bickering, most of what happens between siblings on any given day, is best left alone entirely, treated as practice in a skill children will need for the rest of their lives. When things heat up but nobody's in danger, that five-step sequence does the work. When the roughhousing turns unclear, the fix is a single question asked out loud, is this a play fight or a real fight? Play fights, by mutual consent, are allowed to continue. Real fights, where one child is genuinely getting hurt, are not, and that question alone often stops things before they escalate. And when a fight turns actually dangerous, when someone is about to get hurt, none of the above applies. That calls for describing exactly what you see, in a loud, forceful voice, and physically separating the children until things cool down.

Notice, first, which level of fight you're actually dealing with, because the right response changes depending on how serious it is. For ordinary bickering, practice doing nothing at all, and remind yourself your children are getting useful experience in working things out. When a disagreement starts heating up, try the sequence in order, acknowledge that they both sound angry, reflect back what each side seems to want, name out loud how hard the problem is, tell them you believe they can find a fair solution, and then physically leave the room. If the roughhousing gets confusing, ask directly whether it's a play fight or a real fight, and treat the answer as the rule going forward. The instant a fight turns genuinely dangerous, skip every gentle step, describe loudly and firmly what you see happening, and separate the children immediately.
