My husband and I both enjoyed this helpful dvd to better prepare us for the "BIG" day. We were not able to go to an actual birthing class because of his work schedule. There are a lot of reviews complaining about how the birthing instructor isn't very funny and somewhat cheesy, but it's really not all that bad. We both found her to actually be humorous in most parts. This dvd is very easy to understand and is great, especially for new parents like us. I def recommend it, and also, if you have netflix, you can rent it instead of buying it. But it's dvd by mail only, not instant streaming.
Output:
Positive
