The book I'm recommending (BIRTH) is written also in a very positive way.... very supportive way. It explains birth how it is and how diff stages of labour but what you can do to progress and work your way thru it at each stage. its' very very good. And it reassures you the whole way thru that we are women who are born to do this and our bodies are designed for our babies etc.... it's so good. I feel so positive about birth after reading it!!
Have a read of it at Kmart or somewhere next time you are out!!
