To be a nanny is to know that one day you will have to move on. Nanny transitions are one of the most difficult parts of our job. Luckily, we have Glenda Propst here to talk us through this difficult process. In the words of Nanny McPhee: "There is something you should understand about the way I work. When you need me but do not want me, then I must stay. When you want me but no longer need me, then I have to go. It's rather sad, really, but there it is."
