What I liked about this book is that it takes a remarkably pragmatic view of the potential problems a woman can experience during breastfeeding.
Unlike what seems like lot of other books it doesn't come across as preachy, there are no chapters that make you feel guilty if it breastfeeding doesn't work (when you're trying to breastfeed and it's not working well, it can be very frustrating, and the last thing you want is another book implying you're a bad mother if you don't breastfeed) instead it takes the view that you bought this book because you have already decided want to breastfeed as much as possible and you want help with your problems - the book treats you like an adult.
The book goes not quite a bit of detail, and is not exactly the easiest read. However it does go through a lot of potential problems, and it explains each of them quite well and what you can do about these them, and it even devotes enough space to the problems from the baby's side (e.g. if the baby doesn't want to latch on).
If you get the chance, try to get it and read through it before the child arrives, because it's not an easy subject, but even after the child has arrived it's well worth it.
