Hello, world.

Britain’s Prince William and Catherine, the Duchess of Cambridge, showed off their third child — a boy — hours after his birth on Monday.

Catherine walked out of the hospital with the baby in her arms just before 6 p.m. local time. The boy, whose name has not yet been announced, will be fifth in line to the throne. He is the third child of William and Catherine.
