Well that's true of anyone you hire. No matter who you hire they will be counting on the job. You can't hire on the basis of whom would be less negatively impacted if you had to fire them.
I think you need to reframe your thinking about this hire. You are an employer, hiring a professional. You should act professionally, treat them as professionals, frame the job for which you are hiring clearly, and hold them to the specifics of the job you hire them to do.
If they fail to perform the basic functions of the job that was clearly defined then you have to manage that as any employer would.
Put your professional hat on. I know the nanny/employer relationship is uniquely personal, but it's still a formal employment scenario and you (and the nanny) will be well served by approaching it professionally.
