The wait is almost over. Prince William's wife Kate Middleton -- the Duchess of Cambridge -- went into labor this morning. Once the baby is born, a Notice of Birth will be placed outside the doors of Buckingham Palace.
Royal historian Anna Whitelock tells London's Sky News the birth notice on an easel is a theatrical tradition of the palace. There, the world will finally find out some of the details about the infant like gender, time of birth and weight. Whether it's a boy or a girl, the couple's first child will be the third in line to the British throne.
