Hello. I've had a hard time even deciding to post this question, let alone actually asking his doctor to consider testing for CF. My son is 13 months old, and he has had GI problems since birth. He has GERD and could not tolerate any solid foods till 10 months old. He vomits 2 or 3 times per week on average, and he often has mucous in his poo. His vomit is usually very mucousy too. I never thought of CF until recently because he has had chronic sinus infections, cough, asthma, and one virus after another all winter. His doctors think he's fine and that he's just been unlucky. I guess they are probably right, but all the mucous makes me wonder. Should I just wait to see if he gets better now that spring is coming? I mean, he has some relevant symptoms, but he also is not THAT sick. I really can't tell anymore if I am too carried away with worry or if I am on to something. Thank you for any thoughts.
