Prince William and Kate Middleton, the Duke and Duchess of Cambridge, have been known for their modern approach to parenting. Their choice to hire only one part-time nanny, Maria Borrallo, for their three children, Prince George, Princess Charlotte, and Prince Louis, set them apart from previous royal generations. However, it has now been revealed that Borrallo follows a unique rule when interacting with the royal children.

According to Nanny in a Book author and historian Louise Heren, Borrallo adheres to a strict training from Norland College, which includes avoiding the word "kids." Instead, she must refer to the children as "children" as a mark of respect for them as individuals. This rule is said to be part of Borrallo's overall approach to nurturing and supporting the young royals.

The hiring of Maria Borrallo in 2014, when Prince George was just eight months old, marked a departure from the tradition of employing multiple nannies. The Duke and Duchess of Cambridge have been vocal about their desire for a more hands-on parenting approach and have been actively involved in their children's upbringing.

Prince George, now nine years old, Princess Charlotte, eight years old, and Prince Louis, five years old, have grown up under the care of Borrallo, who has been praised for her professionalism and dedication to the royal family. Reports suggest that she has undergone rigorous training to provide exceptional child care and development.

While Maria Borrallo's strict approach to maintaining discipline and healthy eating habits has made headlines in the past, the revelation about her avoidance of the word "kids" adds another layer to her unique parenting style. This decision to show respect to the children reflects the Duke and Duchess of Cambridge's commitment to raising them as individuals who are valued and heard.

Prince William and Kate Middleton's journey as parents and as a couple has been closely followed by royal fans throughout their marriage. From their early days in college to their eventual engagement, every step of their love story has captivated the public. Christopher Andersen's book, "William and Kate: A Royal Love Story," offers a comprehensive look into their relationship, from the ups and downs to the enduring commitment that has made them one of the most beloved royal couples.

As the Duke and Duchess of Cambridge continue to navigate their roles as parents and representatives of the British monarchy, their approach to parenting with the help of Maria Borrallo serves as an example of their dedication to creating a supportive and respectful environment for their children.
