I have to say that I was rather disappointed to find that all the children are human (mainly Nords, one or two Imperials; not sure I've even seen any Breton kids), they all look nearly identical with variations in haircut and hair color, and they all wear the same clothing with occasional color variations (from the Jarl's son to a peasant's son). Hopefully once the CS is released more kids will be added to the game, especially elf kids, plus more variety in clothing and hair. Khajiit and Argonian kids would be cool, too, though there are so few Argonians that I'm not sure where you'd implement them (Khajiit kids could, of course, follow the Khajiit caravans). Just a thought.
