The royal nanny is not allowed to use this special word!

England - Even though Prince William (42) and Princess Kate (42) look after their three children, they continue the age-old tradition of royal nannies. However, one particular word is taboo for the nanny!

Since Maria Teresa Turrion Borrallo has been looking after Prince George (11), Princess Charlotte (9) and Prince Louis (6), she has had a special rule.

As OK! reported, Maria began working for the family in 2014, when the now 11-year-old was just a few months old.

Although she probably knows the royal family inside out, she is not allowed to use a certain word that many parents probably use all the time.

It is the simple word "children". This is considered disrespectful in front of the royal offspring, as each of the trio should be seen as a separate individual and not generalized.

Because Prince William (42) and Princess Kate (42) have a lot to do, they have hired a nanny for their three children.

But this is not the only rule Mary has to follow. She is also obliged to ensure that the future king's children do not throw tantrums or cry in public.

However, things are not always strict in the royal household. Mary and Kate are said to have a close relationship and work together to bring up the children.

A big emphasis is placed on outdoor play.

There are lots of bike rides, games with the dogs and also gardening.
