How to Stop Siblings From Fighting: What to Say

It is Saturday morning, and Priya is enjoying the first quiet coffee of the week when the thud comes from the living room. Then a wail. By the time she gets there, Arjun, eight, is holding the remote above his head, and Kiran, five, is clutching his arm where his brother just shoved him off the couch.

"He hit me first!" "He took the remote!" "I had it!" Priya hears herself say what she always says: "Who started this?" Both boys start shouting at once, each one louder than the other, and within a minute she is shouting too.

Most parents of more than one child know this scene by heart. Siblings fighting is one of the most common, most exhausting parts of family life, and the usual reflexes (find out who started it, hand out a punishment, make them say sorry) rarely make the next fight less likely. This guide is about the fight itself: what to do in the first 30 seconds, what to say in the fights that come back again and again, which consequences actually teach something, and how to set up your home so there is less to fight about. For the bigger picture of why siblings compete, see our guide to sibling rivalry.

What to do in the first 30 seconds of a sibling fight

How you walk into a fight shapes everything that comes after. The goal of the first 30 seconds is not to solve the problem. It is to stop the harm and bring the temperature down.

When it gets physical: stop, separate, check

Raising Children Network, the Australian government-funded parenting site, is clear about when you need to break up a fight: when it involves shouting, hurtful language or physical violence, or when children are threatening or intimidating each other (Raising Children Network). Their three basic steps are simple: step in if the fight is escalating, stay calm, and tell the children you will talk about it later.

In practice that looks like this:

1. Move first, talk second. Walk in, get between them, and if necessary hold a hand or an arm. Your body does more than your voice here.
2. Use as few words as possible. "Stop. Hands down." Long sentences get lost when children are flooded.
3. Put space between them. One on the couch, one at the kitchen table. Different rooms if needed.
4. Check on whoever is hurt. A quick look, a hand on the shoulder. Then turn to the other child, who is usually just as upset, even if it does not look that way.

Notice what is missing: no questions, no verdict, no lecture. Children are often too upset to take in what you are saying at first, and Raising Children Network suggests waiting until things settle down, which with older children can even be the next day.

When it's loud but not physical

Verbal fights need a lighter touch. If the words are getting nasty or one child is clearly losing, step in with a description instead of a judgment, and offer help instead of a solution.

Sometimes that question is enough. Children who know you are nearby and willing to help often find their own way out of the argument. If they cannot, you can walk them through the talking-it-through steps from our sibling rivalry guide.

When to stay out

Not every argument needs you. If it is a verbal disagreement, nobody is being cruel, and the two of them are roughly matched, standing back gives them the chance to practice. Raising Children Network suggests letting children talk, debate and even argue if they seem to be trying to work things out, and then telling them you noticed (Raising Children Network).

Skip the investigation

"Who started it?" feels like the fair question. In practice, it almost never helps. You usually walked in at the end, not the beginning. The poke that came before the shove happened when you were not looking. And the question turns the fight into a new contest: which child can tell the more convincing story, faster and louder.

Try a sentence you can use for almost every fight instead: "I'm not going to figure out who started it. I'm going to help you two finish it." It tells both children that the goal is solving the problem, not winning your verdict.

The fights that come up again and again (and what to say)

Most families do not have a hundred different sibling fights. They have the same five or six, over and over. That is good news, because a recurring fight is one you can plan for.

Fights over toys, turns and sharing

This is the classic, especially between ages two and six. It is tempting to settle it fast by telling one child to share. But making a child hand over a toy the moment a sibling demands it teaches the sibling that grabbing and yelling work.

Turn-taking works better. The American Academy of Pediatrics suggests a turn-taking timer for toy fights: let the children decide how long a turn lasts, and put them in charge of handing the toy over when the time is up, with praise when they do (AAP, HealthyChildren.org).

Two more things prevent many toy fights. Raising Children Network suggests making sure there are enough toys for everyone, so siblings can play together without always taking turns, and letting each child have some special things of their own that they never have to share (Raising Children Network).

For the exact words in the moment, see what to say when siblings fight over a toy.

Fights in the car

The car combines everything that sets siblings off: no space, nothing to do, often hunger and tiredness, and a parent who cannot step in. Seating helps. Raising Children Network suggests sitting children on either side of a spare seat, putting an adult or older child between the two most likely to fight, or moving the oldest to the front seat if they are old enough under the law (Raising Children Network).

Raising Children Network is explicit about this point (Raising Children Network). Pulling over also works as a calm, predictable consequence. Say it once, before the trip: "If there's fighting, I'll stop the car and we'll wait until it's over." Then follow through, without anger. "We're waiting. The car moves again when hands are in your own space."

Fights over screens and the remote

Screens create fights twice: over who gets to choose, and when the time is up. A clear, written schedule takes the first fight off the table. Raising Children Network gives the example of a routine where each child chooses the program at a set time, and where everyone knows whose turn it is for games, the bathroom and chores (Raising Children Network). The same page notes that if fights over a device start almost immediately, it helps to start your reminders and coaching as soon as the device is switched on, not after the shouting starts.

A simple version that works for many families: Monday, Wednesday and Friday, one child picks the show; Tuesday, Thursday and Saturday, the other; Sunday is a family vote. Write it on the fridge. When an argument starts, you point to the paper instead of making a ruling. For the end-of-screen-time meltdown itself, here is what to say when screen time ends.

Fights over space and privacy

From around six, many fights are about territory: who came into whose room, who touched whose things, who is "breathing on my side." These fights are a sign of something healthy, a growing need for privacy, and they ease when that need has somewhere to go.

Even in a shared bedroom, each child can have a space that is theirs alone: a shelf, a drawer, a box with a lid. Raising Children Network suggests a private space, even just a drawer siblings cannot get into, and modeling the behavior you want, for example by knocking before you go into your child's room (Raising Children Network).

Big kid vs. little kid

When siblings are a few years apart, a common pattern repeats: the little one wrecks the big one's project, the big one explodes, and the parent sees only the explosion. The older child ends up in trouble, and resentment grows on both sides.

Protect the older child's things and time. Give them somewhere to build that the toddler cannot reach, and some time each day when the younger one is not allowed in. And be careful with "You're older, you should know better." Raising Children Network warns that lines like this can leave a child feeling more hurt and resentful, and points out that fair treatment is not the same as identical treatment: you can have different expectations of a six-year-old and a three-year-old (Raising Children Network).

Brothers fighting, sisters fighting: does it matter?

Many parents believe brothers fight more and sisters fight differently. The research does not sort it that neatly, and it is less important than the stereotype suggests. What is clearer is this: a meta-analysis of 34 studies with more than 12,000 children found that more sibling conflict was linked to more emotional and behavior problems, and that the link was stronger in brother pairs and in siblings who were close in age (Buist et al., 2013).

So if you have two boys who fight hard and often, "boys will be boys" is not a reason to look away. At the same time, a lot of what looks like fighting between brothers is actually play. A quick check helps: are both of them laughing? Do they take turns being on top? Does it stop the moment one of them says stop? If yes, it is rough play, and it can be good for them. Agree on a stop word, and step in when one of them is no longer having fun.

And fights that are all words, between sisters, brothers or both (who said what, who was left out, who copied whom), can hurt just as much. They deserve the same attention as a shove.

Twins and siblings close in age

The closer in age two children are, the more they want the same things at the same time: the same toy, the same friend, the same seat, your attention at the same moment. Twins live in permanent comparison, often from people outside the family as much as from parents.

What helps is everything that makes each child their own person. Separate activities now and then, a friend of their own, one-on-one time with you, and as little talk as possible about "the twins" as if they were one unit.

Consequences: what teaches and what backfires

Sometimes stopping the fight and talking it through is not enough, especially when someone was hurt or when the same fight happens after everyone agreed on a solution. Consequences can help, but only some kinds.

What tends to backfire

• Punishing both, no matter what happened. It feels fair, but the child who was hurt learns that coming to you does not help, and the child who did the hurting learns that the cost is shared.
• Forcing a share on demand. The loudest child gets the toy, which guarantees the next fight.
• Always protecting the younger child. The older one learns that they will be blamed anyway, and the younger one learns that a scream brings rescue.
• Labels. "You're always the troublemaker" sticks. Children tend to grow into the roles we give them.

Consequences that teach

Good consequences are related to the fight, short, and fair to each child. Raising Children Network suggests planning ahead: deciding, for example, that you will let children work out minor disagreements, but use consequences for fights involving physical violence, or for fights that happen after everyone already agreed on a solution (Raising Children Network). If your family uses consequences, the same guidance says, make sure they fit each child's age and behavior.

Some that work well:

• The object takes a break. The remote, the toy or the game console goes on the shelf until the children have a plan for sharing it.
• The activity ends for now. If the board game turns into a fight, the game is over, and you can try again tomorrow.
• Repair. A child who broke a sibling's drawing helps make a new one. A child who broke a toy contributes to replacing it, from pocket money if they have it. A child who hurt their sibling finds a way to help them feel better. For the apology itself, see what to say when your child won't apologize.

Time apart as a reset, not a punishment

Separating siblings works best when it is about calming down, not about banishment. "Go to your room and think about what you did" sounds like a punishment and usually feels like one. "You two need a break from each other" is a reset.

The AAP suggests talking with your children, at a calm moment, about how they want to be separated when things get heated: where their own corners in the home will be to get a rest from each other, or whether they would rather try to solve it together first (AAP, HealthyChildren.org). A calm-down spot a child chose is often easier to go to than one they were sent to.

How to get siblings to get along: preventing the next fight

The fights you prevent are the ones you never have to referee. Prevention sounds like a lot of extra work, but most of it is a few small changes to the setup of your day.

Fight-proof the danger hour

Many families have one time of day when fights cluster, often the late afternoon or right before dinner. Raising Children Network suggests thinking ahead about these hot spots: distract children or change the environment when you sense a fight coming, and if you need to make a phone call, set them up with an activity first (Raising Children Network). In practice: a snack ready before pickup, separate activities for the first half hour at home, and the most demanding chores scheduled for a calmer time.

Routines that settle the usual arguments

Every argument that a routine settles is one you never have to judge. Whose turn it is to choose the show, who sits where in the car, who goes first in the bathroom, who feeds the cat on which day: written down once, these stop being fights. Raising Children Network also suggests involving children in setting family rules, because children who help make the rules are more likely to remember and respect them (Raising Children Network).

Games that put them on the same team

Competitive games are a reliable source of sibling fights. Cooperative ones give children practice at being on the same side. The AAP suggests prompting siblings to play as partners (and to switch roles after a while), board games where everyone works together, taking turns adding to a silly drawing or story, and a "kids against the grown-ups" game, maybe letting the kids win sometimes (AAP, HealthyChildren.org).

And when they do get along, say so. "You two built that whole fort together without a single argument" is a sentence your children will remember.

When fighting is more than fighting

Most sibling fights, even loud and frequent ones, are ordinary. Some are not. Raising Children Network recommends seeking help if your children are regularly very aggressive towards each other, if they threaten, intimidate or deliberately humiliate each other, or if one or more of them finds it hard to manage strong emotions or impulses (Raising Children Network).

Our sibling rivalry guide explains the difference between rivalry and sibling bullying, what the research says about the long-term effects, and when to get help.

Questions parents ask about siblings fighting

"They only fight when I'm in the room. Are they doing it for me?"

Partly, maybe. Your attention is the most valuable thing in the house, and a fight is a fast way to get it. That does not mean the feelings are fake. Try giving each child a few minutes of undivided attention at a predictable time each day, and notice whether the "audience fights" drop. When they do fight in front of you, keep your reaction calm and short, and save the big attention for the moments they get along.

"My younger one pokes and pokes, then screams when the older one finally reacts. What do I do?"

This is one of the most common patterns, and one of the easiest to miss. Name it without blame: "I see a lot of poking, and then a big reaction." Hold both children to the same rule (no poking, no hitting), and give the older one a way out that does not involve hitting back: "If he keeps poking, come get me, and I'll help." Then make sure you actually do help when they come.

"Is it okay to let them wrestle?"

Yes, if it is play. Rough play has its own signs: both children are laughing, they take turns being on top, and it stops as soon as one says stop. Agree on a stop word together, and step in as soon as it is used and ignored, or as soon as someone is crying instead of laughing.

"Should I take away screens when they fight over them?"

Taking the device away for a while, until they have a plan for sharing it, is a related consequence and often works. Taking away screens for a whole week because of a fight about something else tends to breed resentment without teaching much. Keep the consequence tied to the fight, keep it short, and give them a way to earn it back: a plan they both agree to.

"They fight all day in the school holidays. Is that normal?"

Very. More time together, less structure and more boredom all mean more fights. A loose daily rhythm helps: some time apart each day (one child with you, one with an activity of their own), something to look forward to, and the same whose-turn routines you use during the school year.
