I purchased this book for my now 8 year old 3 years ago when we had some questions she was asking about her body and I wasn't quite sure how to answer correctly. In the beginning there were some parts we skipped over but as she got older she's read the entire book (she is very smart and mature for her age) now that I am pregnant for the 3rd time, it has been instrumental in helping explain the process of what's going on in my body in a way she understands that is totally age appropriate. She actually brought it to me the other day and we used it to discuss the process of what's going on in my body. This book is amazing!!!
