Royal nanny Maria Teresa Turrion Borallo will play a key role in shaping the Wales' children in their adult lives, an expert believes.
Ms Borallo was selected by William and Kate to help look after George, Charlotte and Louis, and, according to one royal commentator, her input may have a huge impact on the people they turn out to be as heirs to the throne.
Despite being born as senior members of the royal family, the Prince and Princess of Wales have reportedly done their best to give them as normal an upbringing as possible, with Kate thrusting herself into "hands-on" parenting.
But royal biographer Tom Quinn says "the huge pressure of royal tradition cannot be ignored”, meaning the three siblings also have Ms Borallo to help raise them.
Pauline Maclaran, a royal commentator, says the nanny will help ground the three as they grow up, ensuring they turn out to be well-rounded and balanced people when they're older.
Prince William himself grew up partially raised by Charles and Diana's nanny, Tiggy Legge-Bourke, who became a familiar face to royal fans.
And 20 years on Ms Borallo has been seen accompanying the family on multiple occasions since she was taken on nearly a decade ago in 2014, including family Christmas lunch, trooping the colour and family weddings and christenings.
Prince George was just a few months old when she was announced for the coveted role in the royal household, and Ms Maclaren believes her method of raising the children will be fundamental to how they handle royal life in years to come.
"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.”
Originally from Spain, Ms Borallo's influence means Prince George has learned "the basics" of Spanish such as counting to ten, while Princess Charlotte is also learning the ropes with the language.
Ms Maclaren added: “Importantly too, they can offer important emotional support that ensures strong bonds will remain even when the children are adults.”
And Kate's focus on the importance of early years on human development appears to be backed by psychologists, who say the way Ms Borallo helps raise the three siblings will already be wiring their brains into who they become.
Dr Ramya Mohan, a child and adolescent senior consultant developmental psychiatrist at Harley Street, said: "It starts now — from the focus on him during the [King's] Coronation to a lifetime of being in the public eye in a role with rich historical connotations, expectations, and gravitas.
"Needing to adapt in every aspect of his life in parallel with the pressure of being in the public eye in a more evident, scrutinised manner can feel like a tough tightrope walk on his own, despite access to the considerable, planned support and guidance one can expect."
