Poor Tyler!  After a few days of being on the Nutramigen, he had seemed to be doing better, his poop had firmed up a little and his rash had seem better, he now seems to have taking a step back again.  His diarrhea was back, with mucous, and his diaper area is really red and raw looking, and he's been screaming during diaper changes.  I am taking him back to the doctor later today.  They are also going to take some blood to do an allergy test.
