See Princess Charlotte and Prince George's All-Time Cutest Moments from Trooping the Colour!

Prince George made a splash in 2015 — the year he made his balcony debut — when he watched the Trooping the Colour parade from a window at Buckingham Palace and playfully stuck his tongue out.

The little prince showed off his royal wave — and wore the same blue outfit that Prince William wore for his own Trooping the Colour debut 31 years earlier!

One year later, Princess Charlotte attended her first-ever Trooping the Colour in the arms of mom Kate Middleton — and proved that she had already mastered her royal wave!

Prince George had plenty of adorable moments of his own, including when he gave a tiny salute during the flypast.

When it was time to head back inside, Prince George made sure to give the crowds one last wave — to the amusement of his parents.

Fans got a sneak peek of George and Charlotte at the 2017 festivities, as the little royals took in the parade from a Buckingham Palace window.

Once they were out on the balcony, Prince George looked bored — resting his head on his hand — as he waited for the flypast.

Charlotte even rocked the same pose, though George was now all smiles in his little suspenders.

Princess Charlotte is a pro at the royal wave, but she's still ready to learn from someone with more experience. At the 2018 celebrations, she adorably copied the Queen's gesture — and Kate laughed as she caught the sweet moment.

Queen Elizabeth's great-granddaughter Savannah Phillips wanted her cousin George to keep it cool, so she promptly placed her right hand right over the future king’s mouth when he started to giggle.

Savannah knew the cameras were on her, too, as she flashed a sly smile and deadpanned those watching.

Savannah was also caught shushing George, who wore a smirk on his face.

Kate sprung into action when Charlotte slipped during the 2018 balcony appearance, scooping her daughter into her arms. The royal mom had difused the situation within just a few minutes, and Charlotte was all smiles again.
