Arguments between siblings can make even the calmest household feel chaotic. One minute children are playing happily together, and the next they may be arguing over a toy, accusing each other of being treated unfairly, or competing for a parent’s attention.
Sibling rivalry is common, and disagreements between brothers and sisters do not necessarily mean they have a poor relationship. Children living together are learning how to share space, manage frustration, negotiate, communicate, and deal with differences. At the same time, frequent or intense conflict can be exhausting for the whole family.
Parents cannot prevent every disagreement, nor should they be expected to. The goal is to help children learn healthier ways to handle conflict while making sure each child feels valued and supported within the family.
Why Do Siblings Fight?
Sibling conflict can happen for many reasons.
Young children may struggle with sharing or controlling strong emotions. School-age children may become more aware of fairness and compare privileges, achievements, or possessions. Older children may argue over privacy, responsibilities, shared spaces, or different family rules.
Competition for parental attention can also contribute.
Children may compare how much time a parent spends with a sibling, who receives praise, who has more freedom, or who seems to “get away with” more.
Sometimes siblings simply have different personalities. One child may be quiet and organised while another is energetic and spontaneous. Sharing a home does not automatically mean children will always enjoy the same activities or respond to situations in the same way.
Avoid Comparing Your Children
Comparisons can unintentionally increase competition between siblings.
Comments such as, “Why can’t you keep your room tidy like your sister?” or “Your brother never complains about homework,” may seem harmless but can leave children feeling that they are being measured against each other.
Try to address each child’s behaviour individually.
Instead of comparing, say, “I need you to put your clothes away,” or, “Let’s work out how you’re going to finish your homework.”
The same principle applies to positive comparisons. Constantly describing one child as “the clever one,” “the sporty one,” or “the responsible one” can create roles that children feel pressured to maintain.
Allow each child to develop their own identity.
Understand Sibling Jealousy
Jealousy can appear when children believe another sibling receives something they want — attention, freedom, praise, possessions, or opportunities.
A new baby can also bring significant changes. An older child who previously received most of their parents’ attention may suddenly have to share it with someone who requires constant care.
Rather than immediately telling a jealous child that they are being unreasonable, acknowledge the feeling.
You might say, “It sounds like you wish you had more time with me too.”
Recognising an emotion does not mean giving children everything they demand. It simply helps them feel understood.
Make Time for Each Child Individually
Children do not need identical relationships with their parents, but each child benefits from feeling individually important.
One-on-one time can be simple.
Take one child with you while running an errand, read together, have a short conversation before bed, prepare food together, or go for a walk.
You do not necessarily need to calculate exactly equal minutes for every child. Focus instead on creating regular opportunities for individual connection.
This can be particularly helpful during periods when one sibling requires additional attention because of illness, school difficulties, or another challenge.
Should Parents Intervene in Every Argument?
Not necessarily.
When disagreements are minor and everyone is safe, children may benefit from trying to resolve the problem themselves.
If parents immediately decide who is right every time, children may become dependent on adults to settle every disagreement.
You can guide without taking complete control.
Ask:
▪ What happened?
▪ What does each person need?
▪ What could you do differently?
▪ Can you think of a solution that works for both of you?
Step in when conflict becomes aggressive, threatening, repeatedly one-sided, or beyond the children’s ability to manage safely.
Teach Children How to Disagree
Children are not born knowing how to resolve conflict calmly.
They need practice.
Help them learn to express what they want without insults or aggression.
Instead of, “You’re horrible! Give it back!” encourage something more specific: “I was using that. Please give it back when you’re finished.”
Teach children to listen to the other person’s version too.
They do not have to agree, but understanding that someone else may see the same situation differently is an important relationship skill.
Establish Clear Family Rules
Simple expectations can reduce some recurring conflicts.
Your family might have rules about knocking before entering bedrooms, asking before borrowing belongings, taking turns with shared devices, or speaking respectfully during disagreements.
Keep rules understandable and appropriate for children’s ages.
Consequences should focus on the behaviour rather than humiliating the child.
If siblings cannot safely share a particular item because they repeatedly fight over it, for example, the item may need to be temporarily removed until they can agree on how to use it.
Fair Does Not Always Mean Identical
Children often notice immediately when a sibling receives something different.
“You let her stay up later.”
“He got more.”
“Why doesn’t she have to do that?”
Explain that fairness does not always mean everyone receives exactly the same thing.
A teenager may have a later bedtime than a younger sibling because their needs and responsibilities are different. A child struggling academically may temporarily receive more homework support.
Where possible, explain the reason for differences rather than simply saying, “Because I said so.”
Children may still complain, but transparency can make decisions easier to understand.
Encourage Cooperation Instead of Constant Competition
Competition can be fun in moderation, but families do not need to turn everything into a contest.
Look for activities where siblings work towards a shared goal.
They could:
▪ Build something together
▪ Prepare a meal
▪ Complete a puzzle
▪ Create a treasure hunt
▪ Work together during a family game
▪ Help plan an outing
Notice cooperation when it happens.
A simple comment such as, “You two worked that out really well together,” reinforces the behaviour without comparing one child to the other.
Do Not Force Siblings to Be Best Friends
Parents naturally hope their children will remain close throughout life, but sibling relationships vary.
Children may have different personalities, interests, and social needs.
Encourage kindness and respect, but avoid demanding constant closeness.
Older children may need more privacy and time with their own friends. Younger siblings may not understand why an older brother or sister no longer wants to play with them as often.
Relationships can also change over time. Siblings who argue constantly at one stage may become much closer later.
Know When Sibling Conflict Is More Serious
Ordinary sibling arguments are different from repeated intimidation, deliberate humiliation, threats, or physical aggression.
Parents should take persistent patterns seriously, particularly when one child appears frightened of another or consistently has less power in the relationship.
Separate children when necessary and establish clear expectations around safety.
If conflict is severe, persistent, affecting a child’s wellbeing, or difficult for the family to manage, consider speaking with a qualified healthcare, mental health, or family professional for guidance.
Frequently Asked Questions
Is sibling rivalry normal?
Yes. Disagreements, jealousy, and competition between siblings are common. The important issue is how conflict is handled and whether children feel safe and respected.
Should I make my children apologise after fighting?
Encourage accountability, but a forced apology made while a child is still angry may have little meaning. Allow children to calm down, discuss what happened, and then help them think about how to repair the situation.
How can I stop my children competing for attention?
Regular individual time with each child can help. Avoid comparisons and recognise each child’s interests, strengths, and needs without turning them into competition.
Should siblings always share?
Children can learn to share communal items, but they can also have some personal belongings they are not required to share. Clear family expectations can help prevent repeated arguments.
When should I worry about sibling fighting?
Seek additional guidance if conflict involves repeated physical aggression, threats, intimidation, significant fear, or behaviour that is affecting a child’s wellbeing or family life.
