Problem: My husband and I were unable to find any classes in our area that would work for us, so we purchased this DVD. We found it very helpful! I loved that I could go back to it and watch certain parts over again to refresh my memory. If we had gone to a class, I wouldn't have had that luxury. Once I went into labor, I knew exactly what to do and I was able to make it without any drugs. The nurses at the hospital were all asking me if I had gone to a class and I told them about the DVD. They said it must have been good because I did everything perfectly. I would highly recommend this DVD!
Solution:
Positive
