We had a follow-up with the GI in Greensboro today. He was oddly nicer to us (did he find out we were going to see someone else?) and agreed that putting her back on the Prevacid twice a day was fine if it was the only thing that worked. He also said that her diarrhea could be a result of the formula she is on. Because it is already partially digested, it could be just how her system is reacting to it. He didn't seem very concerned. I guess we'll just wait and see what the stool tests say and go from there.
Here are a couple pictures of Rachel before bedtime. She's a little sleepy head. :)
