I have a 3 1/2 year old granddaughter who’s been showing quite an interest in the human body, organs and bones and how they work and what they do. I found this out by accident when I discovered she’d found a few kid friendly videos on YouTube that she was watching.So I ordered this book we could read together and talk about all of the many questions she has. She loves being read to and this book gives us the opportunity to bond and learn together.The book itself is written and illustrated perfectly for kids. I would highly recommend this item for curious little minds that want to know how their bodies are put together and how it works in a very easy to understand language and pictures that further explain how everything works.
