All I tell my families is to nurse a lot and put the baby in a sunny window for 10 min, 2 or 3times a day (maybe even sit in a sunny window while nursing). Actually doesn't have to be a 'sunny' day, since the right rays will penetrate cloud cover anyway, to help clear the bilirubin. Also, just to watch baby's signs--a vigorous baby nursing often and sleeping well with some alert periods is a baby who can manage jaundice. If they get lethargic, hard to wake to nurse, with increasing yellow color, then we worry. But I have seen a few really yellow babies who took a few weeks to totally move the bilirubin out--since these babes were vigorous and bright, we just let things take their course.
