We took Philly to the pediatrician, who did a bilirubin test to check for jaundice, today.  This is apparently standard procedure for newborns discharged less than 4 days after birth.  Philomena’s levels are at 16, so we have to watch them closely and switch her over to formula so that she can get hydrated and pass the bilirubin from her system.  This apparently happens because the liver function is the last thing to develop, and since she was 3.5 weeks early, it’s not quite ready to handle it solo yet.
