Wherever Prince Louis goes, the five-year-old royal is guaranteed to bring light and laughter to any situation as his charming, cheeky personality turns royal stoicism on its head. Luckily for the Prince and Princess of Wales, there’s always an attentive big sister on hand to make sure little Louis is behaving as he should. 

Princess Charlotte, William and Kate’s nine-year-old daughter, was an emblem of royal etiquette as she joined her family on the balcony of Buckingham Palace at Trooping the Colour on Saturday. 

Keeping a close eye on her brother Louis, who was more interested in dancing, yawning and pointing at the excitement below him, Charlotte made sure to remind her sibling of the ‘proper’ way to behave – and one moment from their sweet sibling exchange has gone viral on TikTok.

In a clip from the BBC reshared by CNN anchor Max Foster (@maxfostercnn), Princess Charlotte can be seen telling Prince Louis to put his arms down as the fanfare begins for the national anthem.
