Maria Teresa Turrion Borrallo, the nanny recruited by Prince William and Kate Middleton in 2014, has access to a 24/7 "online support and recovery space" she can go to if her mental health needs it.
Ms Borrallo, from Palencia, Spain, joined the Cambridges when Prince George, eight, was slightly over half a year old.
Less than two years later, Prince Charlotte, six, was welcomed to the world. Fast forward another three years, and the youngest of the Cambridges, Prince Louis, three, arrived too.
Ms Borrallo forged her skills to become a royal nanny through an "award-winning early years degree" at Norland College.
The prestigious school, in Bath, has been placing nannies across the country since 1892. They were once referred to as "the closest creatures to Mary Poppins left in the modern world".

Ms Borrallo has discreetly worked for some other high-profile names, and her studies at the prestigious school, from where others within the Royal Family have also hired nannies in the past, are believed to have prepared her well for what can be a highly demanding job.
But should caring for the three young children ever affect her mental health, the Spaniard can easily obtain support.
The Norland Agency offers its nannies access to a Togetherall, a platform where they can go to if they're "feeling down, stressed, struggling to cope, or just want to talk to people who understand" what they're experiencing.
Norland adds: "It is moderated by trained professionals who are available 24/7 to ensure the safety and anonymity of all members."
All students, including the Cambridges' nanny, can use the service to discuss their worries – "from everyday stresses to major life events".
Mental health is a central topic within the Firm – even more so recently, since the allegations of Meghan Markle, 40, about her struggles in the tell-all interview with Oprah Winfrey, where she said she felt vilified by the press and unsupported by the Royal Family.
Meghan also admitted she'd had suicidal thoughts. "I just didn’t want to be alive anymore," she said. "And that was a very clear and real and frightening constant thought."
Mental health is a matter close to the heart of 37-year-old Prince Harry, Duke of Sussex too. He opened up about being "very close to total breakdown on numerous occasions" in a 2017 Telegraph podcast episode and later, in 2019, announced the documentary The Me You Can’t See with Oprah.

Aired in May this year, The Me You Can’t See shows the two discussing "mental health and emotional well-being while opening up about their own mental health journeys and struggles".
Harry confessed mental health played a fundamental part in his wish to redefine his role within the Royal Family and his decision to step back from his role as a senior working royal and move to the US with Meghan.
The Duke and Duchess of Cambridge, both 39, do great work in raising awareness about the importance of speaking about one's feelings.
The couple spearheads Heads Together, an initiative that strives to "tackle stigma and change the conversation on mental health" as well as raise funds for innovative programmes aimed in particular at school and the workplace.
