How the young Royals enjoyed the Coronation
The prospect of a two-hour church service, full of ceremony and importance, is a daunting prospect for most, let alone if you've just turned five.
But luckily for Prince Louis, the youngest royal at the Coronation had his sister Princess Charlotte to hold his hand, physically and metaphorically.
Meanwhile, older brother, Prince George was part of the ceremony at Westminster Abbey as one of the King's pages.
