[EX Q]: My husband and I are expecting our first baby any day now. We opted to get a childbirth video versus attending a class. After doing some research and getting reccomendations from friends, I decided to purchase this video. While the information on the DVD is helpful and each segment is clear and easy to understand, the instructor presented it in such a way that made extremely painful to watch.The instructor continuously makes annoying jokes, mocks pregnant women and their partners, using the most unfunny and unflattering impersonations imaginable. Watching this woman's attempt stand-up routine was so uncomfortable that we often found ourselves fast forwarding through a lot of it. Please believe that neither me or my husband laughed during this DVD. Not once.I wish we had just gone to childbirth class.
[EX A]: Negative

[EX Q]: Currently, there are no wholes throughout the bed. But, for some reason when I wake up. The bed is already out of air. I only weigh 120lbs. I don't understand why it does that. Please save your money, when you start to have the same problem.
[EX A]: Negative
