When the family turned to go back inside the palace, he even waved to grandpa Prince Charles. 06 of 18 Neil Mockford/GC Images Louis celebrated his first birthday on April 23, which means he’s around the same age as Charlotte was during her first Trooping the Colour appearance. 07 of 18 Prince Louis, Prince William, Kate Middleton, Prince George and Princess Charlotte. Tim Rooke/Shutterstock Prince George, who turns 6 in July, was a little older – nearly 2 – when he made his Trooping the Colour debut in 2015. That’s likely because at 10 months old, he was too young for the exciting event the previous year. 08 of 18 Prince William and Prince Louis.
