It's actually been on the to do list for a while now. It's just trying to work out the logistics that's holding things back. Like, having a kid with another NPC basically makes it so that you can't do any more quests with them, so do I just cut them off like that, or make a separate timeline or something?
And then there's the question of do babies stay babies, or grow up, then does that mean they time skipped, or does that time pass for everyone meaning several years pass? Or because they're a lust doll, and not a real person, so maybe they can age faster or something?
