This is my 3-year-old daughter's favorite book. She has asked for this as a bedtime story every day this week. It even beat out her Frozen book. Her favorite parts are when the egg comes down the "fa fa tube" and the baby with the "um-il-lah" cord. On one page it says "If you're a boy..." to which I turn to her and ask "Are you a boy?" and she'll say "No, I'll find." and flip through the pages until she finds a picture of a boy. This book has opened up discussion on who has labia and who has a penis. Though it did open up a very interesting discussion about the gender of her not anatomically correct doll.

I like the illustrations in this book. The anatomy is cartoony but accurate and the characters are fairly diverse. Though, as a couple reviews have mentioned, there are no non-circumstanced males. And I do wish it mentioned c-sections as well, since my vagina didn't turn out to be "very very stretchy." There also isn't a lot of talk about appropriate versus inappropriate touches.

There is one page about silly made up names for your private parts. I believe it's meant as a tie in if your child has already made up a name, but since we have used correct labels since birth, this page is a little confusing, and I tend to skip it.

I do not think this book is too detailed. It is perfect for preschoolers. There is one picture of an adult male and one picture of an adult female on the page that says as you grow your body changes. And there is absolutely no mention of intercourse. That's left for another day. The most detail this book has on that subject is one page that says when the egg and the sperm meet a baby is formed. No mention on how that would ever happen, just that when "you're much older" girls release eggs and boys make sperm.

This is the perfect book for teaching your preschooler (or yourself) the proper names for their private parts. It's fun and informative and really keeps the child's attention. Could use some more information, but a very good starting place.

It is a very descriptive book. Gives proper names for body parts which all children should know .

Appropriate for preschool up to about age 8, especially if this is their first book about the topic.
It covers basic anatomy with appropriate drawings of the parts you can see and what's inside the body. It explains eggs and sperm and says that when a man and a woman love each other and want to make a baby the sperm joins with the egg and a baby grows. It doesn't explain any further how the two get together.
A couple of things to be aware of: 1. it only depicts a circumcised penis and I'd prefer it educated about both; 2. The back cover is geared toward parents and says things like "aren't ready to learn about sexual intercourse." So, if your child can read be aware of that.
All in all I think this is a good first introduction to the topic for young kids. It provides honest information without being too graphic.

My oldest daughter started asking questions about the differences between boys and girls so I ordered this book. It explains differences in a very simple way without over explaining things or making anyone feel uncomfortable. It does not talk about sex or go into detail about anything beyond anatomy difference, your private areas are only for you, and that a baby is carried in mom's stomach. I would recommend! My daughters are 6, 4, and 3.

Informative but a little to graphic for my 5 year old . He knows his parts but this book is more for 6+ in my opinion . Again really good book !
