Body book for a 3 year old

[monal]

Hi,
My little girl is 3 and has just gone to nursery.

She is really interested in her body and bodies and her private parts and wants to know exactly which part is her vulva, thanks MN, and asks me every time we go to the swimming pool at the absolute top of her voice, why do you have a VAGINA with HAIR?

I would like to get her a book but more of a reference book kind of thing that I could read with her, that is just factual and sufficiently detailed to answer her curiosity without being wildly age-inappropriate. I have The Care & Keeping of You at home but it's for older kids and also it's more about self-care than anatomy.

Do you have any recommendations?

Usbourne do a see inside your body or a human anatomy book with flaps etc which my ds loves. I am not sure though how much detail it would go into about the reproductive organs. My ds has been learning about the heart and he loved this book.
