Kid!fic is around, but scattered, and they vary widely in quality. Here are some I enjoyed:
Catsmeow has the Transliteration Series (http://www.thealphagate.com/viewseries.php?seriesid=288). Devra and JoaG have a newish teen Daniel series, Wayward Son (http://pages.videotron.com/whump2/jdws.html). Anne has several Little Daniel fics here (http://home.germany.net/coolpool/JackandDaniel.html). Annie B's are here (http://brothersinarmsfiction.com/annie/anniels.html), along with a rare, Little Jack series. green_grrl maintains a kid!fic rec list (http://green-grrl.livejournal.com/23017.html) with several more.
