There are many ways to gently teach children about the birds and the bees, but however it's done, there are some details you probably don't need to include. One book, however, might have illustrated a few too many of them.
A mom in London was at a doctor's office where her kids began to read a children's book called Mummy Laid an Egg. It looked innocent enough but on page 8, it started describing how daddy fits into mommy, then, page ten began what she described as "a child-friendly Kama Sutra guide."
The woman's children obviously had many questions about what they just read... and the clown outfits and the balloons certainly added to their curiosity.
