I remember a Sims 2 hack that was something like this. No woohoo, and instead, sims requested babies from a garden flamingo.
Jesus.
That sounds more scarring than introducing your kid to the concept of sex.
That all depends on how you introduce it. For me, it was an animated film called "Where Did I Come From?", which my mother thought would be an educational thing about babies. The only scene I remember was the part where the man and woman were in bed. It zoomed in on cat patterned bedsheets, and after a moment, the cats came to life and started going at it as well. As the age of
four 0, I didn't get it, but my mom was considerably abhorred.
I was fortunated enough to watch that film as both a 6 (Introductory talk) and several times as a 12 (Health class every year, and advanced Biology). Needless to say, it was much more entertainingas a 12. I would love to see the look on the original poster's face if their child brought home the book Mommy Laid an Egg, as that book seemed too "adult" for several of the adults in my Children's Services: 0 to 6 class.
The Sims games are no worse than some of the shows on tv geared towards children.
