Query: Good explanations for "Why" bad explanations for "How"

This DVD spends a great deal of time explaining the benefits of signing to you child and ways to make it fun but doesn't spend enough time showing parents any actual signs to learn or teach their babies. If you are already convinced that you and your child want to learn sign language then this product won't offer much more information than that. In all, there were only a handful of examples of signs being shown and I don't believe it is worth the money if your looking for dictionary-type or reference video."
