My wife was sure we needed to pay for swim lessons. I bought this DVD, and my four-year old went from being a little nervous about blowing bubbles with his nose and mouth in the water, to going completely under water and getting his Spiderman diving sticks off the steps with no problem. In the past 3-4 weeks we have made about 8-10 trips to the Gym pool and he has learned so much. In addition to showing me what to teach, the DVD taught me be more patient, letting the skills emerge gradually. Ironically, in doing so he has learned much faster.
