For most families, The Gruffalo is simply a beloved bedtime story. But behind the walls of the royal household, Julia Donaldson and Axel Scheffler’s famous tale has taken on a surprisingly special place — and Prince William has previously revealed just how much the story has meant to his children.

As the stage production of The Gruffalo celebrates a major anniversary, the spotlight has once again fallen on the unlikely royal connection to the much-loved children’s classic. Prince George, Princess Charlotte and Prince Louis have grown up surrounded by royal traditions, protocol and extraordinary public attention, yet one of their favourite childhood stories is remarkably ordinary.

The revelation first emerged when Prince William met author Julia Donaldson and illustrator Axel Scheffler. Rather than needing an introduction, the future King immediately recognised the creative duo behind the book and made it clear that The Gruffalo was already a familiar name inside his family home.

“It’s a big hit in our household,” William reportedly told them, offering a rare glimpse into the private world of his young children.

That seemingly simple remark revealed something far more personal about royal family life. Away from royal engagements and ceremonial duties, William and Catherine have repeatedly spoken about trying to give their children as normal a childhood as possible — and bedtime stories have been one of those ordinary family rituals.

For Prince George and Princess Charlotte in particular, The Gruffalo became a childhood favourite. The story follows a clever mouse who invents a terrifying creature to frighten away predators, only to discover that the creature he imagined actually exists. Its combination of humour, suspense and adventure has made it one of Britain’s most recognisable children’s books.

But there is another detail that makes the royal connection particularly intriguing.

William’s comments suggested that the book was not merely something sitting on a shelf in the family home. It had become part of the everyday routine of raising his children, with the future King himself acknowledging the impact that Donaldson’s stories had on their household.

And the connection did not end with the book.

The Gruffalo has since grown into a much larger cultural phenomenon, with its stage adaptation becoming a favourite among families across Britain. As the theatrical production reaches its latest milestone, the fact that the story has also found an audience among the Wales children adds another layer to its extraordinary journey from a children’s picture book to a modern British classic.

There is also something quietly revealing about William’s comments. In a family where almost every public appearance is carefully scrutinised, a simple conversation about a children’s book offered a rare glimpse into the softer side of the future King — a father talking about the stories his children loved and the routines that helped make their childhood feel normal.

And perhaps that is the most unexpected part of the story. Behind the royal titles, palaces and centuries of tradition, George, Charlotte and Louis have had something millions of children around the world can recognise: a favourite bedtime story that keeps coming back night after night.

Yet the real surprise lies in just how long The Gruffalo has remained connected to the royal children’s childhood — and why William’s seemingly casual words about the book continue to reveal more about family life behind the palace walls than an official royal statement ever could.

The beloved monster may be fictional, but its place inside the royal household is very real.
