What about more realistic childbirth?

I'm not against adding realism into my game, but only in the form of mods. Adding things like that, to me, would reduce the charm The Sims has always been known for, like how giving birth causes sparkles to appear or Woo-Hoo creates hearts and steam. The Sims has usually done a goofier and more light-hearted take on things and it should continue to do that.
