His four short years have seen him live rather a jet-set lifestyle, with trips around the world, playtime in a helicopter and a personal introduction to Barack Obama.
Little wonder, then, that Prince George is finding school a little heavy-going.
The Duke of Cambridge has disclosed that his son, who started in reception at Thomas' Battersea earlier this month, is feeling a little fed up of going every day.
The Duke has been taking his son to school each morning, clasping his hand on his first day while the Duchess stayed at home with severe morning sickness.
While a nervous-looking George settled in happily on his first day, the honeymoon period appears to be over.
The Duke told a fellow parent on a visit to Milton Keynes: "I just dropped George off and he didn't want to go."
Mother-of-two Louise Smith, 31, spoke to the Duke as he marked the 50th anniversary of her hometown, in Bedfordshire.
He stopped to say hello to her daughters Sophia Thomas, three, and Holly Thomas, one.
She said: "It was really exciting meeting William. He told me he'd just dropped Prince George off at school and he didn't want to go. Sounds a bit like mine really."
While in Milton Keynes, the Duke stopped for a game of table football with users of a mental health service attached to football club MK Dons' Sports and Education Trust.
They set up a grudge match for the Duke to take part in - MK Dons versus his club Aston Villa, with small claret and blue paper kits to stick on the players so he could take the field for his side.
The Duke said "fantastic" and joined in, trouncing the opposition 2-0.
He even got mini MK Dons shirts for Prince George and Princess Charlotte - although he warned he is a die hard Villa fan, saying: "There is one rule in my house but that's it."
Amy Humphreys, health and fitness leader for the service, said: "We gave him shirts with George and Charlotte written on the back but we didn't have a blank one yet for the bun.
"He said he's got one rule in the house which is that Aston Villa is his main team."
After Prince George's first day on September 7, the Duke revealed the new starters had all taken the anxious moment in their stride while it was the parents who were full of nerves.
But even then he hinted it might not always be plain sailing, saying: "We are all seeing how long that lasts before he doesn't want to go."
The Duke was later asked about his brother Prince Harry' romantic life, laughing diplomatically as he avoided the topic of marriage.
Senior members of the Royal family, including Prince Harry, can only marry if the Queen gives her formal blessing, in a calf-skin document called the "instrument of consent".
Paul Wright, general manager of William Cowley Parchment and Vellum, told the Duke during a visit: "If Prince Harry marries Meghan then his certificate will be in our vellum."
Put on the spot, the Duke simply laughed it off and let the boss keep on talking him through the process for producing documents that last thousands of years.
Prince Harry, who is in Canada for his Invictus Games, on Monday made his first appearance hand in hand with girlfriend Meghan Markle.
