The Duke of Sussex is back in town.
The royal's visit to the U.K. for the annual event—which celebrates the young children and those closest to them—was a solo journey, as his wife Meghan Markle and their two kids Archie Harrison, 4, and Lilibet Diana, 2, remained in California.
Ahead of the ceremony, the organization—who shared videos of the 38-year-old chatting and hanging out with patrons on social media—noted that the charity wouldn't be where they are "if it wasn't for his support."
"We talk a lot about how we punch above our weight as we are a small team doing a lot of good work at a high level," WellChild chief executive Matt James recently told People. "And we wouldn't be where we are without the work the Duke has done to help us fundraise, attract supporters and providing a platform to shine a light on the issues being faced by families up and down the country."
Days after her death, Harry—who stepped away from royal life in 2020 and detailed his struggle with the institution in his January 2023 memoir Spare—penned a message honoring his beloved grandmother's "unwavering grace and dignity."
"I cherish these times shared with you, and the many other special moments in between," he wrote in the note. "You are already sorely missed, not just by us, but by the world over. And as it comes to first meetings, we now honour my father in his new role as King Charles III."
