So Audrey, the super-calm baby, has been fussy the last few days.  It progressed from just a little gas (that responded to medicine) to full on stomach pain.  She's been vomiting (so hard it comes out the nose sometimes) and screaming in pain during and after eating.  So today we took a little trip to the doctor to see what is up.  Basically he confirmed what I had begun to suspect: she has reflux.  In spite of this she is still gaining weight - 9 lb 14 oz today, buck naked!  He prescribed a teeny bit of rice cereal added to a bottle of breast milk twice a day.  We go back for her 1 month check up in about a week so hopefully we will see some improvement in her comfort level.  If not we may try a lactose-free formula or give her a baby-dose of antacid.  We'll keep you posted.  Still no signs of true colic - thank heavens!
