Skip the pediatrician when it comes it to CF, GI or pulmonary. You need to take your child to the GI dr at the CF clinic. You do not have to have pain to have reflux. My daughter was going get a g-button at age 5 when the GI dr asked if she had any symptoms of reflux. I said no to all of the symptoms. The GI dr did a endoscopy (down the throat) anyway to make sure. The GI said my daughter had one of the worst cases of reflux she had seen.
