Prince Louis can't stop waving in this cute video—and steals the show on the balcony at Trooping the Colour

The Royal Family is pulling out all the stops for the Queen's Platinum Jubilee celebrations, and this means some royal firsts for Prince George, Princess Charlotte and Prince Louis. Prince William and Kate's adorable trio hopped into the first carriage in the annual Trooping the Colour procession, where they rode with their mom and Camilla, Duchess of Cornwall during the Queen's birthday celebrations. And Prince Louis just could not stop waving excitedly!

The trio sat in a sweet row on their first ride, with Prince Louis sandwiched between his older siblings. The four-year-old, who has long been an enthusiastic waver, was keenly greeting crowds of fans lining the procession when his sister took his hand and tried to place it on his lap. But as People noticed, Louis just wouldn't be tamed, and his arm shot back up for some more waving. We can't with the cuteness.

Eight-year-old George, who took a more chilled approach, looked all grown up in his navy suit and blue tie, while his sister Charlotte, 7, had her hair half up in braids and wore a pretty blue dress with fluttery sleeves. Kate raided the royal archive for Louis' old timey ensemble, a blue-and-white sailor suit that William wore when he was a little boy.

The only accessory that was missing was a few pairs of sunnies—the siblings were definitely squinting from the sun (though we're sure they wouldn't have been appropriate. Sigh.) And props to Kate for wearing all-white Alexander McQueen and not worrying about grubby little fingers dirtying it up. I'm not sure I've worn a single white item in the five years since my kids were born.

Prince William was almost five when he took his first Trooping the Colour carriage ride, adorably hopping over to his mom's side of the carriage for a better view, and Prince Harry was also four during his debut. But the Cambridge kids are regulars at the festivities, showing off their big personalities every year from the Buckingham Palace balcony, where they always watch the annual Royal Air Force flypast. And this year's flypast did not disappoint.

Prince Louis stole the show with his silly faces, holding his hands over his ears as the noisy planes soared past, making funny faces with his fingers in his mouth and generally being a rowdy four-year-old. His faces are destined for meme-dom, so we got the ball rolling on our Instagram. Louis was also photographed having a chat with his great-grandmother, the Queen, on a break from delighting fans with his reactions.

Hopefully now that the kiddies are off duty, they can go get all their beans out and play with their cousins.
