California-born Meghan, 37, is said to have instructed a recruitment agency in Kensington to find a suitable candidate to start within the next three months.
The mum-to-be and husband Harry, 34, are also said to be open to the idea of having a male nanny for their first child.
A source told The Mirror: “Meghan and Harry have clear ideas on how to bring up their children. Meghan was clear in telling recruiters she favours an American over a Brit and wants them to feel part of the family rather than a uniformed member of staff.
“That is important to her, she’s never hidden the fact she is fiercely proud of her American roots. They are keen to explore the possibility of a male nanny.”
The source added the employee will “earn up to £70,000-a-year, depending on experience”.
It is understood that the successful candidate will live at Meghan and Harry’s new 10-bedroom home Frogmore Cottage in Windsor and will have use of a car.
The Norland-trained nanny is fluent in six languages and her job is to educate and guide the youngest royals through life.
It’s not known how much Kate and William pay their nanny, but she does get to call Kensington Palace home and travels on royal tours with the family.
Training at the prestigious Norland college in Bath will set you back £12,000 a year and as a newly qualified ‘Norlander,’ you can expect to earn a starting salary of £26,000 a year.
Norland nannies wear distinctive brown uniforms and bowler hats with a ‘N’ on them.
