The annual Trooping the Colour may celebrate the queen's birthday, but for many royal fans one of the big draws of the military parade and flyover is the opportunity to get a glimpse at the youngest members of the royal family. The famous moment on the balcony of Buckingham Palace [1] when the family comes together to watch the RAF fly-past is a rare opportunity to see the royal family in its entirety, and when the young cousins get together [2], it's always adorable.

Over the last few years [3], Prince George and Princess Charlotte have become the stars of the show [4], and though they had some serious competition from their brother Prince Louis this year [5], they were still a joy to watch as they stared up at the sky, and waved to the crowds. We really will never tire of seeing these sweet royal siblings together, and this year, as they showed their younger brother the ropes, they were just as adorable as ever. See for yourself ahead.
