The bizarre sex-ed book that parents say is more like a "Kama Sutra guide".

A mum from the UK has stumbled upon a children’s book which would make even the most sexually adventurous adult blush a little.

Katherine Peck, a mum-of-two from London, was at her local GP’s office when her son picked up a book called Mummy Laid an Egg.

The booked starts off OK, I guess, by explaining that “Girl babies are made from sugar and spice and all things nice” and that sometimes you find them under stones (not in my experience, but OK).

But then things take a turn for the more bizarre on page six, when the narrator starts talking about Daddy's friendly seed pods which live outside his body. Apparently Daddy also has a tube which the seed pods come out of, when Daddy puts the tube in Mummy's tummy through a little hole.

OK, that's probably fine. It's a cutesy way of explaining sex to kids and even I learnt a few things.

The book illustrates the different ways in which Daddy can stick his tube in Mummy's tummy and WOW - Mummy and Daddy are very flexible and really creative.

They also use a lot of props. And seem to defy gravity.

In her post Peck described the book as a "child-friendly Kama Sutra guide" involving "aerial acrobatics, fetish clown outfits and space hoppers (fun times!)".

The book then details how once the seeds are in Mummy's tummy they start 'The Great Egg Race', where they shout out really British things like 'Come on lads!' and 'We was robbed!' and it all kind of sounds like an episode of Geordie Shore.

Peck says once her son started looking at the book, her eight-year-old daughter also became interested and "cue the four billion questions I hadn't planned answering today".

Peck's original post has already been share nearly 40,000 times and many people have commented - some had even read the book themselves.

"Here's that book I was telling you about that we almost put out in nursery - luckily we noticed!" one person commented. 

Would you let your daughter learn the Botox procedure for fun? Post continues...

"Can you imagine the questions for months from Katelyn, if she read that?" added another.

While one person summed it up perfectly: "Well, that escalated quickly".

Now if you'll excuse me, I've got some, erm, research to do.

What do you think of Mummy Laid an Egg? Would you read it to your kids?
