Sibling Rivalry: When Brothers and Sisters Keep Score

The short answer: siblings keep score when they are compared. Stop comparing, describe each child on their own, and remember that fair means equal attention, not identical portions.

I believe comparison is one of the most expensive shortcuts a parent can take. “Look how nicely your sister is eating.” “Why can’t you be patient like your brother?” It is said to help, on a tired evening. But children hear something the adult did not say. They hear a ranking.

Once a home has a ranking, every cup, every turn, every minute on the tablet becomes a point on a board that only the children can see.

My principle is this: fairness means equal attention, not identical portions.

The names we give, and the names they keep

In many homes, children slowly receive roles. The easy one. The difficult one. The clever one. The funny one. The roles are often true in a small way, which is what makes them stick.

The trouble is that a role is a narrow room. The “easy” child may learn that being easy is the price of love, and stop showing what is hard. The “difficult” child may stop trying to be anything else, because the part is already cast.

And between them, a quiet competition begins. Not for the cup. For the place.

Fair is not the same as equal

Here is something that may surprise you. Children do not always need the same treatment. They need to understand the difference.

Research on siblings found that most children who noticed they were treated differently did not call it unfair. They explained it themselves, by age or by need: “She’s younger.” “He has more homework.” What mattered most was whether the difference made sense to them (Kowal & Kramer 1997).

Later studies point the same way. When a child felt a parent grew warmer toward a sibling than toward them, their low mood could rise and the warmth between the siblings could fall. But where children saw the difference as fair, the path through jealousy seemed to fade (Shanahan and colleagues 2008; Loeser and colleagues 2016).

So the question is not “Did I give them exactly the same?” It is “Did I say why?”

The referee who never wins

When two children bring a fight to you, the quickest thing is to decide who was right. It is also the thing most likely to start the next fight, because one child leaves feeling like the winner and the other like the one who is always wrong.

There is another way, and it has been tested. In one study, parents learned to act less like judges and more like guides: help each child say what they wanted and how they felt, then let the children look for the solution themselves. Their children compromised more, showed less negativity, and understood their sibling’s view better (Smith & Ross 2007).

The American Academy of Pediatrics puts it simply: don’t take sides, avoid comparing children in front of them, and step in if it turns violent (AAP, HealthyChildren).

Small changes worth trying

• Describe instead of compare. “You waited for your turn” instead of “You waited, unlike your brother.”
• Say the reason once, calmly. “She goes to bed later because she is older. When you are eight, you will too.” Then stop explaining.
• Let the clock decide. A timer both children can see takes you out of the referee’s chair.
• Ask the quiet one. The child who complains least may be carrying the most. “Is there something you need from me?”
• Give each child a time that is theirs. Ten minutes, named in advance, kept even on a bad day.

Check the adults first

Children learn how to treat each other by watching how the adults treat each other. If the parents compete, blame, or keep score between themselves, the children will copy it. If one parent favours one child and the other parent favours the other, the house splits into teams.

So the honest question is: Are we doing our role? Do the two of us agree on how we handle fights, behind a closed door, before we face the children? Do we give each child time, or only the loudest one?

And not every fight is about fairness. Sometimes siblings fight because they are bored, tired, or simply in a bad mood. You do not need a theory for each one. You need a few steady rules.

None of this promises fewer fights. Programmes for siblings tend to raise warmth more reliably than they lower conflict. But warmth between brothers and sisters may be the thing that lasts longest, long after the cups and the tablets are gone.

When it is not rivalry

Ordinary sibling fights come and go. But if one child is always the target, is afraid of a brother or sister, or is being hurt again and again, that is not rivalry. A large study linked sibling aggression to more distress in children, especially young ones (Tucker, Finkelhor and colleagues 2013). Step in, keep the child safe, and talk to your child’s doctor or a counsellor. If someone is hurt or in danger now, call your local emergency number.

Take the board away, slowly

You cannot erase a scoreboard in one evening. But you can stop adding points to it. One less comparison. One reason said out loud. One child who hears, alone, what you admire about them, with nobody to measure it against.

Over time, the children may stop counting. Not because everything became equal, but because they no longer need to prove they have a place.

Try it tonight

Tonight, listen to yourself at dinner. Every time a sentence begins to compare one child with another, stop it halfway and finish it differently: describe what one child did, without the other.

“You ate all your vegetables” instead of “You ate all your vegetables, not like your brother.”

Then, before bed, find each child alone for one minute. Tell them one specific thing you noticed about them today. Not a grade. A detail. “I saw you help the neighbour carry the bag.”

Tomorrow, when a fight about fairness starts, try saying the feeling before the facts: “It feels unfair to you.” Do not argue about the minutes or the size of the slice. Let the feeling be heard first. Then, once, calmly, give the reason for the difference if there is one.

Notice which of these small changes made the evening quieter, even by a little. That is the one to keep.
