Full disclaimer: I didn't actually finish this book.
I had one chapter left, but I feel like I definitely read enough of it for it to "count." The truth is that about 1/2 or 2/3 through the book it became obvious the author wasn't going to say anything new; many of the chapters were merely a rehash of what came before, in previous chapters. I feel like this book could have been just as informative as a long read on Slate or The Atlantic; there just wasn't enough to fill a whole book.
That said, I definitely have plenty of thoughts on it, all of them tied up in my own experiences. I was a part-time/weekend nanny for a few months when I was in my late teens. It was a very "interesting" experience, but it didn't take long for me to realize nannying wasn't for me for a whole host of reasons. Now I work as an assistant preschool teacher, which I love, and this means I'm acquainted with a fair number of nannies and at least a few of my coworkers have been full-time nannies at one time or another. SO WITH ALL OF THAT, this book seemed to focus very narrowly on a very specific type of nanny situation, concentrating on foreign, primarily illegal, not-fully fluent in English, nannies who are sending their earnings back home to their families. Many of these women had left their own children behind to come to the U.S. and be able to support them financially. Granted, that's a very interesting situation, and maybe in some places it's the norm but I can honestly say that none of the nannies/families I know who employ nannies are in that situation. So I was disappointed that this book (despite paying lip-service to other forms of child-care and other nanny or babysitter situations) focused almost exclusively on this. I didn't like that.
I also didn't like that there doesn't seem to be much actual insight here. Maybe for someone whose idea of "the nanny" stems from a mixture of Mary Poppins and Fran Drescher there might be something to glean, but nearly everything found in this book seemed sort of, for lack of a better word, obvious to me. Like, live-in nannies have less privacy. Mothers are sometimes/often jealous of the nanny's attachment to her children. Parents typically want the nanny to take on some of the housework while the nanny often considers it not part of her job. There are rarely formal contracts in these positions. Um, yes. DuH?
I think I kept expecting something MORE from this book, which is why I kept going with it. (That, and it's a fairly entertaining, easy read.) But I never got more and now I'm disappointed.
Also, more honesty: it seemed really clear that in the divide between mothers and nannies, the author was strictly on the mom's side. Which makes sense because she's a mother who has employed nannies, not a woman who has/does work as a nanny. But for a book that was supposed to sort of "bridge the divide" it still bothered me.
