They Forgot The Stork
In case you were still a little unsure about the whole "where babies come from" thing, try this step-by-step German children's book. It charts a baby's progress from the initial meeting of the parents, the missionary position, the gestation period, a ride the the "Klinik" in a lovemobile and a really happy newborn popping out of a uterus. Informative and accurate. Couldn't ask for more.
