I took Tyler to the doctor today because when we picked him up from Priscilla's yesterday she said he had projectile vomited him last bottle.  I tried to feed him a little bit twice last night, and he threw it all up both times (but not projectile).  We saw doctor Baranwal today, and she thinks he might have a milk allergy.  She said the combination of the diarrhea, the mucous and blood in his stool (which wasn't obvious, but it showed up when they tested it), the vomiting, the rash around his butt and the eczema getting worse all pointed toward an allergy.  So we started him on Nutramigen (a hypoallergenic formula) today.  Poor little guy.
