It seems the royal children are bound by a surprising rule and procedure when they are at their home cottage in Windsor.

It may come as a surprise to some that the royal children will head outside, no matter the weather, when they are away from front-facing public duties, it has been claimed.

While having fun at their home in Adelaide Cottage in Windsor, Prince George, 10, Princess Charlotte, nine, and Prince Louis, six, are tended to by their nanny, Maria Borrallo.

But it is said that Maria runs a strict protocol including daily outside playtime – even if it is pouring down with rain.

Louise Heren, the author of ‘Nanny in a Book’ told Hello! Magazine: “There will be lots and lots of outdoor play…Lots of bike rides, playing with their dogs, potentially some gardening. … Yes, you are getting mucky with your hands in the soil.”

She added: “If it is tipping it down, they [the royal children] will still go out.”

Prince William once opened up about his children’s passion for the outdoors in the 2020 documentary ‘Prince William: A Planet For Us All’.

Speaking about his inspiration for environmental work, the Prince said: “Seeing my children, seeing the passion in their eyes and the love for being outdoors. They find a bug or they love watching how bees are forming honey.”

He added: “George, particularly, if he’s not outdoors, he’s quite like a caged animal. He needs to get outside.”

According to former BBC royal correspondent Jennie Bond, the Wales family enjoys outdoor activities together. She previously said: “They like outdoor activities, so lots of sport, lots of fun, games in the garden and cycling.”

She added: “Their half-terms are full of things you’d get up to at Girl Guides: bonfires, barbecues, helping out with the gardens and the farm in Sandringham.”

It is claimed the Royal Family love outdoor activities

Meanwhile, King Charles has lovingly revamped his gardens for the delight of Prince William and Kate’s children, showcasing his deep affection for his grandchildren.

The monarch, known for his green fingers, has made significant changes to his royal gardens, ensuring they are a perfect playground for Prince George and his siblings, Princess Charlotte and Prince Louis.

The King, a passionate environmentalist and the most ardent gardening enthusiast in the Royal family has made three substantial modifications to his gardens across his estates.

Even in honour of Prince George’s birth, the King transformed a barren field into a lush woodland on the Birkhall Estate in Balmoral, Aberdeenshire.
