Out of my two girls, our CF Dr. only has my oldest daughter, Kayla, is on Pulmozyme. He has never even suggested it for my younger daughter, Hannah. SHE asked him about it once about a year or so ago and he told her that he didn't think it was something that she needed to start at this point.
That is something that I do love about their dr. He doesn't treat them with a cookie cutter. He treats them as their CF presents.
I hope your daughter's paper went well!
