Today we went to a pediatric GI specialist. They repeated xrays. The Dr said there was still a lot of stool and gas, so the Miralax was not working. I already knew that, but that's okay. They decided to do double the dose to 17g and continue 3x a day for three days and then twice a day (all assuming he has diarrhea). His nutritionist was actually at this clinic today and she thinks after he gets cleaned out, we will do a 3 day fecal elastase test (which is what I have been wanting all along). That will give us a much better idea of exactly how well his pancreas is functioning and how much enzymes he needs. I called clinic today and they said so far only staph is showing up on his last culture, so fingers crossed, it will stay that way!
