Prince William and Princess Kate’s live-in nanny Maria Teresa Turrion Borrallo joined the Royal Family when Prince George was a tot at just eight months old.

While the three children’s parents are known for being ‘hands-on’, the nanny can help alleviate the pressures that come with hectic work schedules, lifestyles, or circumstances – especially given that Princess Kate is recovering from her cancer diagnosis.

Maria Teresa Turrion Borrallo has been the nanny to the Wales children since each of them were small, having started working for the family in 2014 – 10 years ago.

According to Daily Mail’s FEMAIL, newly qualified nannies can earn up to £42,000 for a non-residential role while some earn up to an eye-watering £120,000 after a few years’ experience.

Maria, who trained at the famous Norland College in Bath, appears to have settled well into royal life. The famous college where she studied is widely considered to be one of the best institutions in the world.

The college website reads: “Norland offers world-class training to those aspiring to be the very best professional childcare practitioners.”

In order to be accepted onto the £15,000- a year course you must have at least three Cs at A-Level and you have to show a passion for caring for young children with the college only welcoming around 100 pupils a year.

The subjects that are taught at the school have previously been described as a mix between ‘Mary Poppins and James Bond’ as students will learn everything a variety of skills including self-defence, martial arts and even getaway driving.

Alongside her prestigious training, Ms Borrallo would have also learnt several rules in her job – including having daily outdoor playtime, strict screen time, and no shouting,

One royal commentator claimed last year that Ms Borrallo will have a major impact on their lives in the future.

Royal commentator, Pauline Maclaran claimed she will have a “strong influence” over the children and will help keep them grounded. She added: “I think royal nannies play important roles in the lives of royal children. Apart from looking after their everyday needs and security, they can also offer a lot of support in developing the children’s cognitive and social skills.”

The King, the future Monarch and Prince Harry all formed enduring bonds with their respective nannies.

Helen Lightbody, who joined the royal household a month after King Charles was born in 1948, cared for the Monarch for eight years.

As an adult, Charles continued to visit his nanny, who was known as “No-Nonesense Lightbody” and invited her to his 21st birthday party as well as his investiture as Prince of Wales in 1969.
