In the late afternoon of 15 September 1984, Lady Diana (†36), the Princess of Wales, became a mother for the second time and Prince Harry was born.

The next morning his older brother, little Prince William, was allowed to enter the Lindo Wing of St. Mary's Hospital in Paddington, London, at the hand of his father Prince Charles.

"William has taken to the new baby like a duck to water"

According to Hello, Prince Charles is said to have told an employee a few days later: "William has taken to the new baby like a duck to water. It's worth a guinea a minute watching him enjoy himself. He's been climbing in and out of Harry's cot." Prince William and Prince Harry's grandfather, Earl Spencer, predicted at the time that the two brothers would one day be very close.

"It will be lovely for William to have a companion and a playmate, and someone to fight with," said Earl Spencer, adding, "I'm sure Harry will be a very good chap." He should be right on both counts.

However, the close bond between Prince Harry and his older brother William was tested by Harry's and Meghan's exit from the British Royal Family. According to Royal expert Katie Nicholl, however, both are said to have come closer again in the meantime.
