He's less than 7 hours old, and the new royal baby boy has already made his first official public appearance—with mom and dad, of course. Kate Middleton and Prince William emerged from the Lindo Wing of St. Mary's Hospital in London to present the new royal highness to the world.

They posed out on the steps, in the same way they did after welcoming their first child Prince George, 4, in 2013, and again with Princess Charlotte, 2 in 2015. Kate wore a red dress and the new baby was swaddled in a white blanket with a matching white hat.
