Query: Save your money, only 9 simple signs shown

I bought this book after reading some of the positive recommendations, if you plan on getting other books regarding baby signs you can skip this one. Only nine signs are shown and the signs are so simplistic it is not worth the money. I do not know how this book compares to the ASL version of baby signs, but you don't need this book to do the signs offered here. For instance flap you arms at your side like wings to imitate a bird. Smack your lips together to imitate a fish. All the signs in the book we learned naturally in preschool, and you don't need a refresher on. At the book list price of $6.99 for 9 signs that's about 80 cents a sign to learn stuff you do naturally.
