Archie Harrison celebrated his first birthday on May 6, 2020. To start the day, his parents shared with the public the first new look at their son in 2020. Prince Harry filmed the video, which shows Meghan reading Duck! Rabbit! to Archie.

At one point in the nearly three-minute clip, Meghan is heard saying "Let's turn the page, let's show everybody. Let's go to the next page — look Arch!," revealing his cute pet name.

Harry and Meghan previously opened up about the inspiration behind their son's name, which also went toward their charity project, the Archewell Foundation.

"Before SussexRoyal, came the idea of Arche – the Greek word meaning source of action," they said. "We connected to this concept for the charitable organisation we hoped to build one day, and it became the inspiration for our son's name. To do something of meaning, to do something that matters."

Perhaps this inspiration played a part in their adoption of the new nickname for Archie, too.
