We have another CF clinic appt on Wednesday. My son is almost 6 months old. Last time, the dr told us he was not going to add a neb to our daily routine as it is questionable if they really help with cpt (when healthy). I am going to ask again this Wednesday. I think our CF center is doing a fabulous job and my son is very healthy. I just wanted to get some more opinions on this before we go. Thanks!
