My doctor refused to test my son when I first brought up cf. Months later when he was still sick, I told the doctor it would make me feel so much better if she'd just order the test, just to rule it out. She said okay but stated that he didn't have the symptoms in her opinion. My neighbor, who had an adult son with cf, had urged me to test him. Anyway, most of me felt so silly asking for this test and felt I was wasting everyone's time, but part of me just wanted to rule it out. I was totally shocked when the test came back positive. Sometimes, as moms, we just have to be the advocate for our kid, even when the professionals don't agree.
