What to Do When Siblings Fight
When siblings fight it can be beyond frustrating. Battles can transform moments that you hoped would be peaceful into moments that are fraught with anger and strife.
The fact that it is normal for siblings to fight is little comfort while their wars are raging. So, can anything be done to promote a ceasefire, or perhaps even an alliance between brothers and sisters?
Why siblings fight?
Children are a work in progress. They do not come complete with impulse control, empathy or the ability to put situations in perspective. In time, they will learn and develop the skills to help them co-exist peacefully with other humans. Unfortunately, it is a slow process
This underdevelopment of personal and social skills, along with the fact that siblings spend prolonged amounts of time together in confined spaces, means that sibling spats are to be expected.
In fact, a certain amount of conflict can be beneficial. It is healthy for children to learn to use their voice and establish their boundaries. Of course, this is often less glamorous than it sounds. It is less gently enforcing personal expectations and more rolling around on the floor, battling over the remote control.
In some homes, however, the battle between siblings can be a never-ending struggle.
Look for the root cause of discord
If your children do not seem to like each other, working out the root cause is important. This may be something that shows in the things they most often fight about. Sometimes it may be due to a clash between needs or personalities. One child may be naturally loud whereas the other struggles with too much noise, or one child may love company, but the other needs their own space.
Sibling fights are also more common when children feel like they don’t get enough attention from their parents or caretakers. If a child is hungry for more connection with their adult, they can begin to resent their siblings with whom they have to share attention.
Prevention is better than cure
Trying to tame two or more children in the midst of a spat is not fun. I do not think this is just my personal opinion. I have met other parents, and no-one likes playing mediator. Is there a way to create a culture where fights are less likely?
Redefine fair
Many siblings fight when one of them believes that a situation is unfair. Children often go through a stage when they believe that everything needs to be equal to be fair. They are not yet able to look at the nuances of a situation, rather they see things as black and white.
For example, perhaps one child was playing with a neighbour in the garden and missed their screen time. When they come in, their sibling has started watching a show. The fact that they have unequal amounts of TV time may be all the first child sees, disregarding the extra fun they had in the garden.
The truth that not everything has to be equal is one that children need to learn.
Replacing fairness with kindness
As your children go through life, there will be times when situations are unequal. Perhaps one of your children is in a friendship group that loves parties, therefore receives more invitations. On the other hand, your other child may be old enough to enjoy more freedom and liberty.
Try to teach your children to replace their strict expectation of fairness with kindness. Encourage them to celebrate each other’s successes and be happy for each other’s wins. This will take time and won’t be an easy process. Of course, allow them to feel disappointment for themselves, too. The ability to feel conflicting emotions is one that they will soon tune into. Remind them of the times that they won and their sibling backed them up.
Allow them to set their own boundaries
Give your children permission to set appropriate boundaries around their bodies, space and possessions. This can be even more important when children share rooms. In a shared room, you may need to get creative. Perhaps you could invest in bed canopies, so each child has a little hidey hole that is all theirs. If possible, divide storage so that they have their own drawer or shelf.
Sharing is a great skill to have. There will be times when sharing should be encouraged. However it is important you don’t make them share everything. Allow them to have things that are there own.
In the same way, there are times when children will have to deal with other people and socialise, but they should not be forced to entertain their siblings. They must be allowed time on their own if they need it.
Set clear and consistent rules
Although, as we have already discussed, things will not and can not always be fair, the fundamental rules should be the same for every child. If there is no screen at the table, that should apply to everyone. No hitting means no hitting, even if it is the littlest hitting the biggest child.
There may be exceptions if you have children who have additional needs. There will also be differences in things like bedtimes, and the amount of independence allowed as children mature and age. You can allow for that whilst also being consistent in the expectation that each child is respectful and kind.
Make time for each child
A child with a strong connection with their parent or main caregiver will feel secure and have better mental and emotional health. This can help them regulate their emotions which in turn will help them to deal with conflict in a more pragmatic way.
One-on-one bonding time is important for building that strong connection. Try to find fun things that you and your child both enjoy doing, and take a little time, when possible, to share the activity with them.
Look after their bodies as well as their minds
Hanger is a real thing. It is not just hunger that can turn your sweet little angels into wild hyenas; lack of sleep and movement can also have a big impact on mood and behaviour.
If your children are in school, you may find that they fight with their siblings more when the holidays come around. To combat this, maintain pockets of routine throughout the holidays to help sleep. Try to get outside, no matter the weather, for a little bit each day.
Encourage your children to work together
A simple way to get your children to work together is to set them a joint challenge. It might be that they need to work together to clean a room, or that they have to collect a certain number of stars between them to earn a treat.
Be sure to structure challenges in a way that each child can and must contribute so one child isn’t carrying the others.

What to do when siblings fight
No matter how well you prepare at times children will fight. When they do, it can be infuriating. You might find yourself tempted to shout louder than them, and thus initiate a three-way war.
Let’s look at some positive ways to cope when siblings fight.
Implement a healthy time out
Time-outs, when used correctly, can be a great way to cool a situation down. When siblings are in the middle of a fight, they are likely to be emotional and frustrated. It is hard to get a child to think rationally when emotions are high. Give each child a place to go and sit, away from the fight, and away from each other.
Time-outs work better when children have an element of control in them. If you ask a child to sit in their room for five minutes there is the chance that they will stomp upstairs and sit seething for five minutes. If, on the other hand you ask a child to go and sit upstairs until they have calmed down and can talk about a situation calmly, they will regulate their emotions in less time, and likely come down in a better place mentally and emotionally.
The element of control that you have given your child will empower them, and the fact that coming out of time-out depends on fixing their attitude will motivate them to work towards being calmer. Of course, there are times when a child will pretend to be calm just to avoid a time-out. This is a bonus. Tell them as long as they prove through behaviour and words that they are calmer, they can come out, and they will be likely to fake calm and in doing so actually feel calmer too.
Give them room to work out a solution
It is tempting to jump in as soon as a conflict arises. Sure, there will be times when we need to for safety or just self-preservation, but sometimes let your children work things out for themselves.
This is hardest when you have a child who has a stronger personality than another as you may worry the gentler child will get stomped all over and taken advantage of. The truth us that children need to learn to handle situations on their own, and fighting their own battles with siblings can be an important step towards that.
That doesn’t mean that you don’t have input at all. Spend time with your more dominant child encouraging them to listen to their siblings, and with your passive child helping them think of ways to express themselves. There will be moments where they don’t manage, and that is okay. You have to lose sometimes to learn.
Take each situation as it is
It is tempting to look at history and behaviour trends when you are having to mediate fights. If one child is often mischievous, you may have an inkling that they are at the root of most conflict. However, each situation should be taken at face value, and each child given a chance to put forwward their opinion.
Take time for you if you need it
There are so many things that we need to look after, it is easy to forget to look after ourselves. To be able to stay calm, we need to remember to prioritise self-care.
If the fighting gets too much, there is no shame at all in asking your children to go into separate calm calm-down spaces for a few minutes and play quietly so that you can breathe. In fact, making sure that they are safe while you take time to self-regulate is great parenting.
A final note
It is hard when our children fight, but hang in there. Parenting can be a gritty and messy journey, but by making it through we will teach our children about perseverance.
I wish you all the peace
