Following the death of the Queen, Harry and Meghan's children have become His Royal Highness Prince Archie of Sussex and Her Royal Highness Princess Lilibet of Sussex.
Meghan Markle, Carrie Underwood, Tamron Hall and Rachel Platten are just some of the famous moms with newborns at home.
Media and well-wishers were camped out in Windsor on Saturday - as they have been for days - awaiting the birth of the couple's first child.
The child is unlikely to ever become king or queen, but the presence of a half-American who may choose to hold dual nationality could shake up the royal family,
Will Baby Sussex be an American? Will the baby have red hair? Could he or she one day become king or queen?
Royal watchers went into a frenzy after Prince Harry and Meghan Markle posted new photos with children on Instagram.
