Being a nanny to the rich and famous is not an easy job, but it seems that those that do make it to the upper echelons of society, do so thanks to their training. In fact, they will mostly go to a college that has been established just to go ahead and train you to be a first-class nanny.
The college is called Norland College and the chances of you getting a place there will be slim as it is fully booked due to the prestige that is attached to it. Actually, the nanny to royal children George and Charlotte was trained there. It seems that aside from being shown how to look after children they also become experts at avoiding the press photographers that could chase after them and also different aspects of how to defend themselves using martial arts.
That really is not a nanny that you want to get on the wrong side of.
