Query: Best educational dvd in our library!

This is by far the best educational dvd I've seen yet. Exciting and engaging. Definitely holds the interest of kids. My 3 1/2 yr old LOVES it, usually asking several times a day to watch it. Before this dvd he could only recognize a few letters by name and did not know ANY of the sounds. Within 3 days of watching the dvd he began to talk about letter sounds throughout the day, and a week later could give the sounds of most all the letters. My 5 yr old has greatly benefited from it as well. We plan to purchase other Leapfrog dvd's! Worth every penny!
