Query: needs lots of explanation for people who don't sign

Our daughter uses ASL to communicate and I bought this book for her nurses, thinking that it would give them some basic vocabulary to use with her. The pictures are very basic and it is hard to understand what kind of movement is going on. There are no written explanations for performing each movement. This makes it difficult for someone to know if the sign is correct. (Not important if you are using signs short term, but important in our case.) I highly recommend the Signing Time video series. Lots of very useful signs and the videos are just as interesting as Elmo or Barney to our daughter!
