Due to their hectic schedule, the royal couple must ensure that their family unit runs like clockwork, and to do this Kate and William turn to the infamous Mary Poppins figure within Kensington Palace, the Cambridge's nanny Maria Borrallo.
The Sun reports that the most famous nanny in England is Madrid born, and was trained at the prestigious Norland College in Bath.
According to the publication, Norland College has educated over 10,000 nannies since its erection in 1892 and provides au pairs for only the most high profile of families.
According to The Sun, the nannies at Norland have a strictly "no nonsense" approach to raising children.
Norland expert Louise Heren told Fabulous Online: "There will be no messing. That’s because Maria will be aware that as they step off planes, holding mum’s hands, smiling and waving to the crowds, there can’t be any crying or terrible twos or tantrums.”
Although Maria is strict, Louise said the tiny royals will have plenty of opportunities to play outside: “There will be lots and lots of outdoor play, that’s the one thing you could say Norland are old-fashioned about. Loads of fresh air.
“Lots of bike rides, playing with their dogs, potentially some gardening. Norland are very into teaching children through play."
Louise also guessed that Meghan Markle and Prince Harry, who are expecting their first baby in April, may also hire a Norland nanny.
Louise told the publication: "Personally I think she’d make the right decision to have a Norland Nanny."
