Input: My husband and I purchased this DVD after attempting to attend an in-person childbirthing class....they just weren't for us. We loved being able to watch this DVD at our leisure in the privacy of our own home. This was one of two DVD's that we purchased and this one was by far the best. Sheri's sense of humor was perfect for the subject matter in my opinion. It really put my mind at ease (a lot of the other courses really scared me) and I feel extremely prepared for labor and delivery. I would highly recommend this DVD to anyone who wants the benefit of being knowledgeable of labor and delivery, yet is hesitant to join an in-person class. I'll certainly keep this one and watch it for subsequent pregnancies.
Output:
Positive
