Query: Outdated

This was the first book that I bought when I found out that I was expecting twins and I found it to be outdated and full of a lot of biased information. The author has her own thoughts about what type of diet you should eat and advocates natural childbirth but doesn't provide a very comprehensive point of view to assist those that may not want to experience childbirth the way that she has. If you share her views then this book will be very helpful to you.I also tried contacting a lot of resources at the back of the book and found most of the numbers to be disconnected.
