In Skyrim, children couldn't be killed so if you destroyed a whole village, they would still be roaming about. Creepy. I also think it's creepy they never grow, but that would be complicated.
Our discussions on this topic have always ended in "no children". Consider also that we intend to have a believable reputation system (someone must witness or discover what you did and also recognise you for plausible reasons). It's sad to have no children but we also don't want to make a game where you can abuse them.
