This is a wonderful resource to what can be some very difficult conversations! It helped us beautifully open the door to talk about some topics that are easily swept under the carpet, but need to be addressed. Full of great information. There is a page informing girls about tampon use that was just a wee bit much for her (and me too for that matter), so we just skimmed over it with the agreement that we will come back to read it together when she thinks that she is ready. Just be advised that it is there before you pass the book off to your little gal.
I bought this book for my 11 year old daughter. She loves the book. It has so much information about how her body is changing in text that she can relate to. I wish I would have had a book like this when I was her age.
