Is this book well-written? No. The content is repetitive (and not in the helpful way kids books typically repeat information), the speech bubbles are not engaging or realistic and the body parts are not properly labeled (no “vulva”, no “urethra”, no “anus”).
Is this book inclusive? Again, no. The book equates sex (and a child’s sex organs) with gender (“boys grow up to become men, and have penises”). There is no recognition—even in a subtle or discrete way—to the fact that trans identities exist.
Would I recommend this book? Not really. It’s a frank explanation of different bodies, which is great, but in a non-compelling way that is regressive and closed-minded, which is not great.
