With a tween girl making sure we talk about all the things that have to do with the female body can be daunting to say the least. My daughter and I have so enjoyed reading these books together and they have really helped me to make sure I cover all the topics she needs to know about. I highly recommend these books and feel like they really are age appropriate for the recommended ages of the books. I find my daughter reading the books on her own and she has even gifted them to friends because she likes them so much. I feel she is as prepared for puberty as I can help her to be and these books have played a vital role.
