Prince Louis has officially made his first appearance at Trooping the Colour, the annual event celebrating the Queen's birthday. The one-year-old looked sweet as ever looking outside the window next to his siblings, Prince George and Princess Charlotte, as they await the royal fly past.

Please take a moment for his grumpy baby face!
Prince George was just shy of two years old before he attended his first Trooping the Colour in 2015, and Princess Charlotte had just turned one when she attended in 2016.
