Q: I've read this book with much expectation, it was very boring all through out the book
A: Negative
Rationale: Review writer does not like the book because it was boring, therefore it is a negative review.
Q: I was on the fence about a child birth class, so I bought this video. I watched the first lesson on her website and that was really helpful. I really liked it. Sheri is fun. She knows her stuff and you feel like you are in the class with them. It did drone on at some points (medical interventions/medications/cord blood banking). When you get to the second disc, she talks about medications, positions, and really important stuff, but after a few mins it gets to be too much. Watch this in small increments! It makes processing the information so much easier. You can always go back and watch important sections again :-))) I plan on buying the breastfeeding video!!
A:
Positive
