I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Why? Review writer does not like the book because it was boring, therefore it is a negative review.

New input: I was very happy with this DVD set (and in fact just ordered the breastfeeding DVD from the same instructor). I watched it in lieu of attending childbirth classes and do not regret that decision. I had read several books about labor and delivery, etc., and can't say that the video really contained a lot of new information but it brought the information together nicely and made me feel more prepared overall. I also appreciated the fact that the instructor did not spend a lot of time on breathing techniques and did not overly emphasize natural childbirth. Instead, she discussed the desirability of postponing medications until the labor is well underway because of the cascade effect of interventions (which seems sensible to me). But she certainly didn't try to push going natural all the way. As for the humor, it's not anywhere near as bad as some other reviews have made it out to be.
Solution:
Positive
