Learn the proper wave
You know that Windsor wave: keep the hand straight and subtly twist the wrist – and don’t flap with the whole arm. Both Prince George and Princess Charlotte already seem to be mastering how to wave to onlookers. Their current choice of wave is a bit more enthusiastic than the rest of their family’s more delicate style, but they’ll likely tone it down when they’re older.
Don’t keep every gift
The public loves giving presents like books and stuffed animals to royal children, but the kids might not be able to play with them. According to official royal policy, any gifts received on an official duty aren’t the young royals’ personal property but belong to the queen, who has the final say in what’s kept and what will be donated.
Learn a foreign language
As figureheads for an entire nation, the royal family is expected to be able to speak in foreign tongues during official visits – and that training starts young. Queen Elizabeth II is fluent in French, Prince Charles and Prince William can speak at least six languages between them, and Prince Harry has spoken Arabic during a speech in Dubai. From a young age, royal children are expected to follow in those language-learning footsteps.
