This is a great compliment to the popular book "the baby signing book." I found that the videos made it very easy to remember signs. It provided a fantastic visual as compared to a static picture with arrows in a book. And a lot of the words provided good memorizing tips. The free version is a great start to testing out key words. But I think the full version is great for the more serious parent who doesnt have enough time to read/study from a book. I was able to learn a lot of signs from this app and incorporate it into conversations with my eight month old. I only wish they had play through of the videos as opposed to pressing forward to the next word. And if this was possible, playing from different start points especially in my favorites section. Happy First Time Mom.
