AN EDUCATIONAL book from 1975 about how a baby is conceived is freaking the internet out thanks to its cartoon-like, rather graphic pictures.

The book, How a Baby Is Made, is penned by Danish author Per Holm Knudsen, and painstakingly details the baby-making process from a man and woman meeting, to conception, to the actual birth.

The fuss all started when Crysta-Mai Elassaad shared photos of the book on Facebook. 160,000 shares later, adults who almost certainly know how a baby is made were calling the book everything from traumatising to creepy to absolutely hilarious.

The information in the book is actually pretty sound, but what really freaked people out was the illustration of the moment the baby emerges ...
