irony is kinda the right reaction to this.
in the first game i think there wasn't any children. at least i can't remember.
the second game had children, and the german version of the game had them simply removed, breaking some things.
one of the kids fell into a fountain and in the german version you were never able to find them, because there simply was no child.
also i remember there was a town with stealing children all over it. (the one where you get the car)
there were no children either, making some quests impossible to solve and stuff like that.
now in fallout 3 i pretty much killed everyone in megaton, except for the little girl running around screaming.
i remember there was a little boy, too, but i never saw him since i started killing everyone.
but now everybody is dead anyway, because i blew the bomb. >=)
i guess there will eventually be a mod, that enables you to kill the children.
but it needs to big rather big, since you have to catch all the eventualities of quest essential characters and what those actions invoke for reaction on other NPCs and your karma.
and the next step is, that the media all over the world start calling fallout 3 the "childmurderers playground" or something like that.
similar to GTA:SA being called a sexgame, because some modder enabled previously disabled gamecontent . . .
we all remember that . . .
Oh that GTA:SA Gawd i sure did love that HOT COFFEE that mod served us players, Mmm, Mmm mmm good to the last drop. Boy those country girls of Cj's sure could suck the chrome off a trailer hitch and lay back with a beer, now those were ladies......
