The Prince and Princess of Wales have always been meticulous when it comes to their children’s upbringing.

From hiring the best nanny to ensuring their privacy, they spare no effort in providing a normal and nurturing environment for their little ones.

One such aspect of their parenting approach is the ban on a particular word in the presence of their eldest son, George, and his siblings.

In 2014, Prince William and Princess Kate enlisted the services of Maria Borallo, a seasoned nanny who trained at the prestigious Norland College in Bath.

Maria quickly became an integral part of the family, caring for George.

When Princess Charlotte arrived in 2015 and Prince Louis in 2018, Maria seamlessly transitioned her role to cater to all three children.

Living with the family at Kensington Palace and accompanying them on royal tours and visits, Maria has adapted well to her royal responsibilities.

However, due to her training, there is one word that Maria is forbidden from using in the presence of the young royals – “kids.”

Author Louise Herron, who spent a year researching for a documentary on Maria’s college, shed light on this intriguing rule.

In an interview with the Mirror, Louise revealed that the nannies at Norland College are taught to use the word “children” or the actual names of the children when addressing them.

The word “kid” is strictly prohibited as a mark of respect for the individuality of each child.

This rule, ingrained in Maria’s training, is likely something she carries with her in her role as the royal nanny.

Despite their royal status, Louise believes that George, Charlotte, and Louis lead relatively normal lives at home.
