Great learning tool. I bought this book for my grandchildren, and they loved it! The sing-along nature of the lyrics really sticks, and they memorized "how to stop the spread of germs" quickly. When I tunefully say, "Use your sleeve....", or "Wash your hands....", the kids will finish the line and hurry to comply! I recommend this book to parents, grandparents, daycare workers, and all folks who read to young children.
