Embark on this exploration of sibling dynamics, birth order theory, famous family drama, and the memories that shape us, while celebrating the lifelong bonds that brothers and sisters hold
As much as they drive us crazy, no one gets us quite like our siblings. Our earliest memories often involve them. They were our first best friends. They were regularly our worst enemies. They were the ones we played with, laughed with, argued with, and cried with.
Every family make up is different, but the dynamics between siblings have a profound impact on shaping who we are. Usually, it was the eldest child who called the shots, the middle child causing mischief, and the baby of the family who seemed to get away with everything. But for all their faults (and the occasions where we genuinely thought we hated them), our siblings play such an important role in our lives.
Celebrated every year on April 10th, National Siblings Day is a chance to honour these unbreakable bonds. It’s a reminder to spend some quality time with our brothers and sisters and reminisce on the good old days. Even if you no longer live in the same household or even country, why not take this opportunity to reach out, share a funny memory, or catch up on life.
In the spirit of National Siblings Day, we’re shining a light on famous families and looking at what birth order might say about you. Settle in, enjoy, and have a little laugh with us as we unpack the beautiful chaos of growing up with brothers and sisters.
The History of National Siblings Day and What It Means to Us
We’ve all celebrated Mother’s Day and Father’s Day, but Siblings Day is often overlooked. National Siblings Day was established in 1995 by Claudia Evart, founder of the Siblings Day Foundation. After losing her two siblings early in life, she wanted to create something in their memory. Claudia even chose the date in honour of her sister, Lisette’s birthday.
At Katch, this day holds a particularly special place in our hearts. Our PR agency has been built on strong family values, and the name itself is a heartfelt tribute to our founder Georgie’s late sister, affectionately known as ‘Catch’. The company was launched on her birthday, and even the signature pink colour comes from a moment of her humour, after Catherine once said she wanted everyone to wear outrageous shades of pink at her funeral.
It’s those memories that remind us why siblings matter so deeply, and why their influence never really leaves us.

Famous Families
Throughout history, the dynamics of family life have been a source of fascination, entertainment, and sometimes conflict. Unlike friends, we don’t choose our family, which means the most opposing personalities often grow up side by side. As much as we may disagree or clash with our siblings, they have a way of teaching us about ourselves, and it usually ends in a funny story we look back on later.
Remember the wacky games and creative ideas you and your siblings came up with as kids, born out of the sheer boredom of long summer days? Think slip and slides made from dish soap and plastic bags, or mud pies carefully garnished with leaves.
As children, Wilbur and Orville Wright did just that. The two middle children in a family of seven spent their early years exploring, experimenting, and dreaming up seemingly outlandish ideas. In adulthood, that shared creativity paid off, leading them to achieve the first powered, sustained, and controlled aeroplane flight. Two years later, the Wright brothers built and flew the first practical aeroplane, sharing the credit and maintaining a close bond throughout their lives.

Alongside the siblings who achieved great things together, there have also been plenty of famous family feuds. Often cited as one of the earliest sibling fallouts, the story of Cain and Abel, sons of Adam and Eve, centres on jealousy and comparison, a classic case of sibling competition. We also can’t forget royal sisters Mary and Anne Boleyn, who found themselves caught in a high-stakes rivalry at the court of Henry VIII.
In the world of sport, Venus and Serena Williams show that even the closest siblings can struggle when competition gets personal. Unstoppable as a doubles team, things became far more complicated when they faced each other across the net. Then there are the Gallagher brothers, from the band Oasis, whose ongoing back-and-forth has become almost as famous as their music.
We can’t talk about sibling dynamics without mentioning the Kardashians. Love them or hate them, turning everyday family squabbles into reality TV was nothing short of genius. The show was an overnight success with Keeping Up with the Kardashians running for 20 seasons on E!, followed by five seasons of The Kardashians on Hulu.
While they’re now one of the most influential families in modern pop culture, their arguments and laugh-out-loud moments remain surprisingly relatable. Those early seasons were reality TV at its peak, gifting us iconic lines like momager Kris Jenner snapping at Khloé, “Khloé, would you stop taking pictures of yourself? Your sister’s going to jail.”
Birth Order Theory
There’s a reason some of these famous family dynamics feel a little too familiar. Birth order theory, first introduced by psychologist Alfred Adler, suggests that where you fall in the sibling lineup can shape certain personality traits. It all comes down to the roles we slip into, and the expectations placed on us, sometimes without anyone realising.
The eldest often grows up responsible and reliable, quietly carrying the weight of being “the example”. Middle children tend to master compromise, independence, and the art of being overlooked. Youngest siblings usually bring the charm and creativity, occasionally leaning on others to pick up the slack, while only children often show a mix of confidence, maturity, and strong opinions. None of it is set in stone, but it does explain a lot at the dinner table.

Hold Them Close
Sibling relationships can be confusing, loud, and occasionally exhausting, but they are also fiercely loyal. You might argue, roll your eyes, or swear you are done with them for the day, but the second someone else has something to say, you are right there defending them. Maybe it is that black-and-white nature that makes these bonds so strong, just as quick to clash as they are to forgive.
Even as we grow older, there is often a childlike thread running through these relationships, equal parts teasing, comfort, and shared history. So, this National Siblings Day, hold them a little closer, laugh at the chaos, and remind them that no matter how much time passes, you’ll always have their back.
