As a former nanny, I always took my shoes off in people’s houses or if I noticed that they were wearing them I would ask if I should take mine off.
As an experienced nanny, she would have worked with all kinds of parents and has a good idea of what she prefers. After all, you’re not just working with children but you are working with their parents too. It could have been your husband’s tone or the vibe he gave that maybe suggested to her that he is patronising or micro-managing. It could have triggered a memory of a time when an employer was very pedantic at the interview stage and then went on to be a nightmare to work for and she regretted not listening to her gut feeling.
As a nanny, there isn’t much progression within the job- though it pays very well- which means you find other parts of the job to upgrade. Imagine that your first job paid the standard rate, the employer’s house was old and crumbling, you looked after three children, one of which was still a baby, were expected to do babysitting two evenings a week at no extra pay and the family paid you cash in hand. You would want your next family to pay you a bit more and declare all of your earnings, live in a beautiful and uplifting house in a nice area, look after 2 well-behaved school-aged children, do only light housework, no babysitting in the evening because they hire someone else for that, get on well with the parents and feel like you’re part of the family rather than a servant.
I once turned down a family where the mum seemed highly strung, overly expressive in her negative emotions when talking to her baby even though everything seemed perfect on paper. I said to myself, hell no. She also didn’t like me because I had asked her lots of questions like ‘how do you react when a nanny makes a mistake or hasn’t completed her work by the time you get home from work?’
Also, if she is very experienced, that’s not always a good thing- she might have become very jaded and wants the best working conditions and the highest pay while delivering only a good enough service. She knows how to please employers without going the extra mile. She also knows that she is highly in demand as an experienced nanny and can pick and choose exactly what she wants.
You’re better off with a less experienced but more keen younger nanny who wants to be a great nanny and learn a little on the job.
