None of us will deny the fact that explaining the "birds and the bees" to our little ones can be more than terrifying.
There are, of course, many ways to deliver the news that babies do not come from the stork, but we may have found the best one.
"Mummy Laid an Egg" is the name of a sex education book that Katherine Peck recently discovered in a doctor's waiting room, and it is hilarious.
Katherine explained in a Facebook post that her eight-year-old, Ayla, found the "silly baby book particularly interesting. Cue the 4 billion questions I hadn't planned answering today."
The book starts off rather innocent, describing that little girls are made with "sugar and spice, and everything nice," but takes a turn for the bizarre.
On page six, young readers are introduced to "daddy's friendly looking seed pods," and are informed in a matter-of-fact way, "this fits in here."
The book goes on to describe, in the most child-friendly way, how a man and woman have sex to make a baby.
The description also includes different sex positions, which Katherine described in a Facebook post as "a child-friendly Karma Sutra guide."
Following the positions, some of which look pretty challenging, kids are introduced to the "great egg race," where the sperm compete to make the baby.
"Come on, lads!"
Katherine's post has been shared over 30,000 times, and has mums across the globe in absolute hysterics.
"Anyone who can make a baby on a skateboard, well done. I don't think I could," one person wrote.
"I will never be able to look at balloons and space hoppers in the same light ever again," another commented.
This book was written by Babette Cole, and won the 1994 British Illustrated Children's Book of the Year Award.
According to Babette's website, Mummy Laid an Egg has sold an astonishing 2,500,000 copies worldwide.
All-in-all, the book gave us a right giggle, but may be sort of inappropriate, we can't really decide.
