George and Charlotte Show Prince Louis the Best Part of Trooping — Watching from Palace Window!

Princess Charlotte and Prince George are showing younger brother Prince Louis the royal ropes!

Little Louis, who celebrated his first birthday in April, couldn’t wait for his Buckingham Palace balcony debut to show off his first-ever royal wave. The prince joined big sister Princess Charlotte, 4, in taking a peek out the palace window to catch a glimpse of the crowds gathered for Trooping the Colour festivities on Saturday, raising up his hand to greet spectators and excitedly pointing at the growing crowds.

George, 5, also joined in the fun, pressing his face against the window next to his siblings before heading out onto the balcony to watch the flypast.
