Prior to the birth, few details of the couple's birth plans were released. Kensington Palace had said that the birth would be revealed only once Harry and Meghan had the opportunity to celebrate privately. Unlike Harry's brother Prince William, they didn't share where the baby would be born.

Harry and the former "Suits" actress married last year in a chapel on the grounds of Windsor Castle, about 20 miles west of central London. The celebration saw movie stars mingling with royalty.

The palace announced Meghan’s pregnancy in October.

In early March, the palace announced that Harry, 34, and Meghan, 37, would create their own household, complete with their own communications staff based at Buckingham Palace. The move would mean that their operations would be separate from those they had shared with Prince William and his wife Kate, the Duchess of Cambridge.
