My youngest son (10 yrs.) asked me how a baby would get a stork’s bite.
"Stork's bite": literally translation from the Dutch word “ooievaarsbeet”, meaning “a reddish birthmark in the neck”.
So I explained him that during the delivery the stork, with its beak, holds the baby in its neck. He looked at me in disbelief.
Then I asked him: “Or do you still think babies come from sex?”
