This is a neonatal dx!! What's it doing on peds?
Anyway, now that it's there...HYDRATE, and bili lights, once you're sure it's a high INdirect bili, not direct. They often get a septic w/u and antibiotics as well. Encourage stooling, usually not a problem once they're rehydrated. They should be in an incubator because you take off their clothes under the bili lights (newborns can get cold stressed), and don't forget to cover their eyes.
If it's a high DIRECT bili, a cause needs to be found. You can soemtimes get it lower w/phenobarb and/or actigall [ursodiol], but determining the cause is critical.
If the baby is breast fed, mom may be having problems w/milk supply and adequate hydration [for herself], so she should have a lactation consult. She MUST keep pumping q 3-4 hrs AROUND THE CLOCK (rent her an electric pump and use a double set-up if possible), and she should be allowed to stay w/the baby.
Sometimes a 24 hr rest from breast feeding/milk is ordered to r/o true breast milk jaundice, which is rare. We feed babies who, for whatever reason, can't go to breast, Nutramegen, which is so disgusting they can't wait to go back to mom. I also like Lactofree for these babies, especially if they get diarrhea after a day or two on antibiotics and under the bili light.
Check Merenstein and Gardner's book for more info--I like their explanation best.
This wouldn't be too much info, would it?
