Balancing royal duties and engagements with looking after their children can often be a juggle for the Duke and Duchess of Cambridge.
Luckily, they've got the services of a well-trained nanny to call on to help take care of Prince George, Princess Charlotte and Prince Louis. Maria Borrallo, who trained at the famous Norland College, was hired by Kate and William when George was just a few months old. And ever since she has becoming a massive helping hand and has settled well into royal family life. But there is thought to be one word Maria is banned from saying whenever she's in front of the royal children, and it's all because of her training.
According to author Louise Heren, who spent at Norland College researching for a documentary, students are taught never to say the word kids.
Instead, youngsters should always be referred to as children or by their names.
Speaking to the Mirror, she said: "The word kid is banned. It's a mark of respect for the children as individuals."
However, its not the only rule that's been laid down in the Cambridge household, according to a source.

They told the Sun : "Shouting is absolutely ‘off limits’ for the children and any hint of shouting at each other is dealt with by removal."
However, things could look set to be very different for the Cambridge children and their nanny very soon.
The family are rumoured to be moving to Windsor, which will see them swap the grand Kensington Palace for a "modest" four-bedroom home.
And this will reportedly they will not have a live-in nanny for the first time in George, Charlotte and Louis' lives.
The Cambridge family are said to be upping sticks to move to Adelaide Cottage, which is nestled in the heart of the Queen's 655-acre Windsor estate and is extremely close to Windsor Castle.
There are only four bedrooms in the cottage, one for the couple and one each for their three children.
And according to The Telegraph, this will represent a "significant change" as their nanny Maria Borrallo will no longer be able to live with them.
However, Ms Borrallo will reportedly be kept on full-time - although will live elsewhere alongside other staff that previously lived with the family including a housekeeper and a chef.
Meanwhile, not having a live-in nanny isn't the only change the Cambridge children will see on moving to Windsor - they are also rumoured to be moving schools.
The children are likely to be educated locally and are rumoured to be joining Lambrook School in Berkshire as day pupils.
