This children's book on the miracle of life is very graphic and very anatomically correct

Da solen stod op om natten, often translated as How a Baby Is Made or The True Story of How Babies Are Made, was originally published in 1972. Written by 1971 by Danish psychotherapist Per Holm Knudsen, it actually won a Danish Ministry of Culture Children's Book prize for its, uhh, highly accurate depiction of where, in fact, babies come from:

On one hand, this is uhhh, pretty graphic. On the other: well, maybe it's better that we stop lying to children and treating sex like some shameful secret. So in that case, it's pretty good. Just not in a creepy way.

But if that's the kind of thing you want to share with your kids, you can pick up a used copy on Amazon for around $50.
