Why Sibling Rivalry Keeps Running Your Household
The hidden dynamics underneath sibling conflict...and how to spot them in your own children.
Last week I shared the three phrases I have on repeat to help shift our home from competition to connection.
The phrases that have become so deeply embedded into our family culture that my girls now roll their eyes and say, “We knowwwww, Mom. We’re a team.”
If you missed that one, you can read it here.
But I promised I’d tell you something important this week.
The real reason your kids fight.
Because when we understand the why underneath the behavior, we can actually create real change in their relationship. And maybe, just maybe, preserve a tiny bit of our sanity in the process.
The thing I’ve learned after years of studying child psychology, sitting with siblings in therapy sessions, and approximately 47,000 hours of breaking up sibling arguments in my own house is this:
The fight is almost never about the toy.
Do they truly want that mangled, slobbered-on rainbow unicorn stuffy they’re currently willing to destroy their relationship over?
No. Absolutely not.
And yet there they are, acting as though possession of this unicorn determines who will inherit the family fortune.
The same thing happens with the blue cup. The last waffle. The seat next to Mom. The remote control. The winner of a game. The empty bottle of nail polish that somehow became the most valuable item in our home last Tuesday.
The toy gets blamed for a lot of things it didn’t do. Because most sibling fights aren’t actually about the thing they’re fighting over. They’re about what’s happening underneath the fight.
What looks like a fight over a unicorn is often something much bigger.
A fight about fairness.
A fight about attention.
A fight about power.
A fight about feeling left out.
A fight about frustration.
A fight about skills that one child has and the other child is still developing.
That’s why sibling conflict can feel so confusing as parents. We’re watching one argument. But underneath that argument are two completely different humans bringing their own personalities, needs, fears, strengths, and struggles into the moment.
One child might be seeking connection.
The other might be seeking independence.
One might be trying to protect something.
The other might simply be acting on impulse.
One child may feel completely overwhelmed while the other is having the time of their life.
And suddenly the interaction starts making a whole lot more sense. The real story is underneath.
Now, I could have handled the rainbow unicorn fight the way most of us are tempted to.
“She had it first.” “Give it back.” “Go to your room.” Fight over.
At least for the next ten minutes. But then what?
The same issues would show up in the next fight. And the next one. And the one after that. Because while the unicorn might change, the underlying dynamic usually doesn’t.
So mamas, I think we need to ask a different question.
Not: “How do I stop this fight?”
But: “What is going on underneath this fight?”
That’s where we start understanding the needs, personalities, skill gaps, and fears driving the behavior. And that’s where we can actually create lasting change.
Keep reading and I’ll walk you through how I started decoding my own daughters’ fights, the personality differences, temperament traits, skill gaps, and unmet needs hiding underneath the behavior - and how you can start doing the same thing with your own kids.
And my friends... this is where the paywall goes.
Think of it this way.
For 1/16th the cost of last week’s random Target purchase, you’ll get weekly parenting insights, sibling strategies, motherhood conversations, child psychology tips, emotional intelligence tools, and the real, unfiltered version of raising tiny humans.
Now don’t get me wrong. Those throw pillows absolutely tied the room together. But they probably won’t help you understand why your children are currently fighting over an empty bottle of nail polish.
This just might.
Let’s dive in.
