Pancreatic sufficiency can change. It would be my guess Holly needs another stool test. The basic rules of poop are, if it floats, it has undigested fat in it. Therefore the fats she's eating are passing right through her, and not helping her put on weight.
Does Holly go to a CF center? If you have one locally (or within a few hours) I would recommend seeing the team of doctors/nurses/specialists at a CF center. I wish I could help more, but it sounds like she needs more tests done.
