Prince George and Princess Charlotte’s favourite book

Prince George and Princess Charlotte have different personalities and interests, but the royal siblings both enjoy reading the same book. Their father, Prince William, has revealed what his two older children share reading as their favourite past time, and they have a book that they love to read.

Earlier this week, the Duke of Cambridge visited London’s new Tusk Rhino Trail, which is a series of 21 rhino-themed art installations around the city that aims to draw attention to the dwindling population of rhinoceros. While there, he met author Julia Donaldson and illustrator Axel Scheffler, who were behind the popular children’s book “The Gruffalo.”

“I know who you are,” the Duke told them. “It’s a bit hit in our household, ‘The Gruffalo.’”

As his and Kate Middleton’s third child, Prince Louis, is still too young to read or appreciate being read to, it’s assumed that William was talking about George and Charlotte enjoying the book.

“The Gruffalo,” first published in 1999, is about a mouse who, in order to trick dangerous animals into thinking he has a scary friend, claims he will be dining with his friend, a Gruffalo. Unknown to him at first, the Gruffalo is a real creature, which threatens to eat him as well. The book had been adapted into a 30-minute animated film in 2009, and as a West End theatre production in 2014.

Meanwhile, a royal insider has revealed to Us Weekly how George, 5, and Charlotte, 3, go about their normal day. Since school has already begun in the UK, the Cambridges’ schedule pretty much revolves around the little royals. William and Kate apparently take turns driving George to his private school, Thomas’s of Battersea in London, and walking Charlotte to Willcock’s Nursery School in Kensington.

George is already in Year One, and he is said to be studying subjects like geography, maths and French already. He will also be given homework.

As for personalities, George, according to the publication’s source, is a shy boy, while his younger sister is “very bubbly.”

“She’s definitely the biggest character of the three children at the moment,” the source said, noting that the little princess loved to play hostess at their home in Kensington Palace. “She’ll come up to guests and ask them if they want tea or coffee or offer them sweets — so adorable!”

Louis, 5 months old, is “very quiet and content, always smiling and happy.”

William and Kate reportedly “very much prioritise” giving their children as normal as possible childhood. They want to bring up George, Charlotte and Louis in “as normal an environment as possible over anything else,” even though they are heirs to the crown. George is the third in line to the throne, after his grandfather, Prince Charles, and his father. Charlotte and Louis are the fourth and fifth respectively.
