My husband and I were skeptical.  I bought this DVD on a whim and it stayed in its wrapper for 2 weeks before we watched it.  Our baby fussed for 2 hours at night, fighting sleep, but obviously exhausted, well fed, and wearing a clean diaper.  My daughter fussed while we watched the video and we calmed her right there as we watched the techniques.  We can get her to sleep in less than 5 minutes, rather than try to calm her fussing for over an hour, like we had done before.
