He's also learning how to play tennis
William and Kate are also keen tennis players, and their children appear to be following in their footsteps. Both George and Charlotte have had tennis lessons, with the Princess reportedly learning at the exclusive Hurlingham Club in London.
George, meanwhile, had his first experience with tennis at the family's home in Norfolk, Anmer Hall, where he grew up before moving to London.
During an engagement in her role as patron of the Lawn Tennis Association, the Duchess told retired player Greg Rusedski: "[George has] got a racket and he enjoys playing tennis." But Kate also admitted that, at his age, he just "wants to whack a ball".
Greg later revealed: "She says with George just being four, he wants to whack a ball, so she was asking what sort of stuff she should be doing. They will struggle at that age to hit a ball. She said he's interested in it, but more in whacking the ball."
And during Wimbledon 2018, William and Kate spoke to men's winner Novak Djokovic. "How are your children?" the tennis star asked, to which William replied: "Very well thanks, very well. Trying to get a tennis racket in their hand – and a football!"
