My husband and I were not able to attend a birthing class, so the doctor suggested we rent/buy a video. We decided on this one, and although the 'teacher' was a bit corny it was helpful. I especially liked that you could fast forward and skip parts! All in all it was a worthwhile purchase and proved helpful to us both.

Ex Output:
Positive

I think that this is a great album. My personal favorite song on it is "Like I Love You." Probably the most popular song on it is "Takes a little time." My friend is crazy about that song! You should buy this CD!
