Family life and behaviour

Sibling conflict

Two pieces, not one.

For most children, a brother or sister is the longest relationship they’ll ever have. These pages cover the fights that aren’t fair, favouritism that may or may not be real, the older child who has lost their place and the younger one who has been overshadowed. They’re for the parent who keeps ending up as referee.

What to do first and who else can help are free to read and to print.

What the library holds on sibling conflict

For a child aged

From the therapists

What to do first

Brothers and sisters fight, and for most of them it’s how they learn to negotiate. A household with no conflict in it is usually one where something is being suppressed.

  1. Stop refereeing who started it. You weren’t there, and ruling on it is what keeps it going.
  2. Give each child ten minutes with you that the other one isn’t part of. Most sibling conflict is competition for something in short supply, and that’s you.
  3. Intervene on safety, not on fairness. Fairness is not achievable and chasing it exhausts everyone.

Quick tips

12 on sibling conflict

Short pieces for the moment in front of you, each with things to try.

Family transitions

The Second Child, and the First

When a new baby arrives, every first child wants to know whether they are still the one.

Try this

  • Carve out ten exclusive minutes a day with the first child.

Family dynamics

The Sibling Who Has Noticed Everything

Your child has already noticed something is different at home, so tell them briefly what it is.

Try this

  • Tell your child briefly, in the car, and use the clinical name.

Family dynamics

The Sibling Who Stops Asking

While one child struggles, the other may become very easy to live with and keep their worries to themselves.

Try this

  • Keep something every week that’s theirs alone, such as bath time, bedtime or their swimming.

Things to do together

2 on sibling conflict

Small, repeatable things to do with your child, with what to watch for and when to get help.

To do together · About 15 min

Time alone with each child

A regular time with each of your children on their own, doing something they choose. Keep it short enough to protect every week.

What it is for. It’s hard for brothers and sisters to share their parents’ attention. A child who can count on time that is theirs alone has less reason to fight over the time that has to be shared.

  1. The first step Find a slot for each child that you can keep: fifteen minutes after the youngest is in bed, the walk to Saturday swimming, breakfast out once a month with a teenager. Put each one in the diary.

Safety. Make the time when another adult is in the house or the youngest is asleep. Don’t leave a young child on their own to free up time for another.

When to get help. If, in your time together, your child tells you that someone is hurting them, that they are hurting themselves, or that they do not want to be alive, stay calm, thank them for telling you, do not promise to keep it secret, and act that day, using the routes under “If you need help right now”, at the foot of every page. If one child is regularly hurt or frightened by a brother or sister, step in each time and make sure that child is safe, and talk to your GP or their school if it goes on. If a child becomes withdrawn or anxious, stops talking to you or falls behind at school for several weeks, talk to their school and your GP.

The other four steps, and your part in it, are in the library.

Who else can help

This usually starts at school rather than at the surgery. The adults who see your child every day are the first people to tell, and often the fastest route to a change. The GP is there if it persists or deepens.

Where to start

  • Your child’s school

    The pastoral lead, the head of year, or the form tutor. Free, already knows your child, and often the quickest way to get something changed at school.

    Before or alongside anything else. A school cannot act on what it has not been told, and what you bring is often what it did not have.

  • Your GP

    The gateway to everything the NHS offers a child: paediatric assessment, a referral to CAMHS, and support for you as the parent.

    Ask for a double appointment. Describe the pattern over weeks rather than the worst single day, and say plainly what you are worried about. Bring a written list; the ten minutes go quickly.

    www.nhs.uk/service-search/find-a-gp

  • Private therapy, if you can meet the cost

    A registered counsellor or psychotherapist, found through the BACP or NCPS directories. Waiting lists are shorter than the NHS and you choose who your child sits with.

    When waiting is the problem, or when you want a particular kind of help. What to look for, and what to expect, is set out in our guide to finding a therapist.
