Sibling conflict is a tale as old as time - William and Harry, Liam and Noel, Kim and Kourtney. But squabbling children does not automatically mean they’re going to be enemies for life! Conflict between siblings is often impulsive rather than deliberate. More often that not, it comes from a place of insecurity and immaturity. Even the most cherished children struggle to understand that love is infinite, and so, most sibling rivalry is based on the resentment of having to share parental love and attention.
Conflict between sibling is developmentally normal and research says that it may happen up to eight times an hour. I’d argue that some days it can feel like 800 and other days my children play like they’re the best of friends. Whatever is happening between your children, this blog post is going to explain everything in more detail and give you some helpful tips to move forward with.
Is sibling rivalry ever a good thing?
Whilst rivalry between siblings doesn’t feel pleasant, the way in which we navigate it can enable our children to develop important life skills. Disagreements between siblings teach children that we all have different perspectives. With support, they can learn to stand up for what they believe in and they may also develop skills such as persuasion and conflict resolution. For me, the biggest positive with sibling rivalry is that it’s a sign that your children feel safe in your home. Siblings who feel they aren’t safe and therefore need to stick together are less likely to fall out with each other because they’re dependant on each other.
Why might they be arguing?
There are lots of reasons why our children might fall out and the more we can identify this, the easier it becomes to deal with. Things such as boredom, an unmet need or jealousy all have a lot to answer for when it comes to disagreements between our children. Sometimes in a family, one child is more dominant and will trigger the other for a reaction. Other times you might feel like either child could be to blame. I’ll talk about this more but it’s very important that we stay impartial and avoid taking sides.
Can sibling rivalry effect self-esteem?
Sibling comparison is very different to disagreements between siblings. Using language like “your brother is sitting nicely, why can’t you?” has been found to have a negative impact on a child’s self esteem. As parents we must be mindful when navigating these sibling fall outs and I’d warn against using them as an opportunity for healthy competition.
