I used this book with both of my children, there is a 13 year gap between them. It was extremly helpful the first time and it was even more so the second time. The format is great, the information is plentiful. I saw that some reviewers said it was idealistic, there is nothing wrong with helping a woman have the best possible pregnancy. Each woman should take from it what is good for her and leave what is not. No one book is going to be specific to Mary, Jane or Sue, but this books covers so much that each of these women will be able to gain a great deal of information about their preganancy. Please enjoy it, I did, twice.
