"Meghan and Harry were forced to let the nurse go in the middle of her second night of work for being unprofessional and irresponsible," the authors write.
Noting that the couple hired a second night nurse who "did a fine job," the book goes on to claim that because of the undisclosed incident with the first nurse, "neither found themselves comfortable sleeping through the night without going to check on Archie regularly."
According to the book, Harry and Meghan ended up handling the night wakings and feedings on their own and hiring a nanny during the day.
Finding Freedom also details the couple's early romance, struggles within the royal family, and their new life outside of the British monarchy.
A spokesperson for Harry and Meghan released a statement ahead of the book's publication, saying, “The Duke and Duchess of Sussex were not interviewed and did not contribute to Finding Freedom. This book is based on the authors’ own experiences as members of the royal press corps and their own independent reporting."
