I'd recommend reading up about metabolic side effects of antipsychotics (bad for adults, but every child psychiatrist is scared to death of making kids fat, for good reason), and pubmed for jack mclellan's AACAP pediatric bipolar treatment and diagnosis guidelines.
there isn't a lot of great literature about using atypicals for aggression management in kids (kiki chang has a few small papers, but I couldn't ever find any great reviews or anything), but that'd be a topic to explore as well.
for inpatient know everything you can about geodon, abilify, prozac, concerta, and clonidine. you'll get a lot of mileage out of just knowing those 5 meds ridiculously well. kids of course take everything adults do, but there's just less data out for them, so a smaller number of agents get used as first line. if you see a kid on paxil, lamictal, and zyprexa, either they've failed a lot of other agents, or their psychiatrist sees mostly adults, or their psychiatrist smokes crack.
and remember, even if she's a raging borderline now, she might not be when she's 18. unlike in the adult world, where your only hope is borderline burn out, kids actually have some unstable personality traits that sometimes actually get better.
