(AP) — Palace officials say Prince William’s wife Kate has given birth to a baby boy.

Officials said Monday the baby was born at 4:24 p.m. and weighs 8 pounds 6 ounces.

The infant will become third in line for the British throne after Prince Charles and William.

Kate checked into a private wing at St. Mary’s Hospital in central London early Monday morning.

William spent the long hours of labor at her bedside. This is the couple’s first child.
