The royal baby is officially here!

Kate Middleton gave birth to her third child, a baby boy, with Prince William on Monday at St. Mary’s Hospital in London, and the family is obviously thrilled. While we can’t wait to see what the baby boy looks like, 4-year-old Prince George and 2-year-old Princess Charlotte were among the first eager little people to get to meet their new sibling.

Prince William left the hospital’s Lindo Wing (in his Range Rover) to pick up Prince George and Princess Charlotte at Kensington Palace. According to People, little George was at school when Middleton gave birth while Charlotte was at home.

So what did they wear?

For the royally cute occasion, George looked adorable in his school uniform, which consists of a collared shirt, V-neck sweater, and shorts. Charlotte kept it girly and fun in a little blue dress with a sweater and a matching hair bow. The two held onto dad’s hands and waved to the camera as they made their way into the hospital. Kensington Palace shared additional footage of their arrival.
