Key takeaways

  • Some sibling conflict is normal and teaches negotiation; step in when anyone is hurt or it becomes unfair.
  • Avoid taking sides or comparing children; coach them through solving it.
  • Fair doesn’t mean identical: give each child what they need, and one-on-one time.

Sibling fights can make a calm home feel like a war zone. Some conflict is normal, and even useful: it’s where children practise negotiating, compromising and repairing relationships. Your job is less referee and more coach.

Why siblings fight

  • Competition for attention and resources
  • Different ages, temperaments and needs
  • Boredom, tiredness and hunger
  • Copying how conflict is handled around them

When to step in

Step in immediately if anyone is being hurt, if one child is being bullied or overpowered, or if things are escalating fast. For minor squabbles, give them a moment to sort it out.

Scripts for common fights

Fighting over a toy

“I see two kids who both want the truck. What could we do so you both get a turn?”

Offer a timer if they need structure.

“That’s not fair!”

“You wish you had the same. In our family, everyone gets what they need, and that’s not always the same thing.”

Teasing and name-calling

“Name-calling isn’t allowed. Tell your brother what you’re upset about, using real words.”

Physical fights

“I won’t let you hurt each other. You both need a break. We’ll sort it out when everyone is calm.”

For hitting, see our guide to handling a child who hits.

What to avoid

  • Taking sides without knowing what happened
  • Comparing siblings: “Why can’t you be like your sister?”
  • Labels like “the difficult one”
  • Forcing apologies instead of helping them repair
  • Punishing both children by default: a logical consequence tied to the fight, such as the toy going on a shelf for a while, teaches more

Build the relationship

  • Special one-on-one time with each child reduces competition for attention.
  • Team goals: tidy up together, build a den, beat a timer.
  • Notice kindness: “You shared your snack. That was kind.”
  • Family rules everyone agrees on: no hitting, no name-calling, ask before borrowing.

When to get help

If one child is consistently targeted, if fights are frequently violent or if the conflict is affecting a child’s wellbeing, talk to your pediatrician or a family counsellor.

Frequently asked questions

Is sibling rivalry normal?

Yes. Most siblings fight at times. Their relationship often improves as they grow and develop better skills.

Should I punish both children?

If you don’t know who started it, separate them to calm down and then help them problem-solve, rather than guessing.

How do I prepare a toddler for a new baby?

Talk about the baby, involve them in small ways and protect special time together; our guide to preparing for a new sibling has more. Expect some regression; it usually passes.
