Prince Harry and Meghan Markle were in New York City for their Archewell Foundation’s first-ever summit in honor of  World Mental Health Day.

The Duke and Duchess of Sussex hosted a parent’s summit around children’s mental wellness in the digital age. The summit brought together parents who have experienced tragic loss, connected to their child’s social media use, for a discussion on building community and creating a safer online world for young people.

The discussion was hosted by Carson Daly and also included U.S. Surgeon General Vivek Murthy.
