I have two sons, one is 3 and the other is 12months. My second child is under weight he only weighs 16 lbs. and he does not crawl or walk. so his doctor has ordered a cf test at childrens hospital. I am really stressed out. I had a amnio with my second child. (because I was 39) and nobody ever asked me if I should get tested for cf or have the amnio tested for cf. Doesn't that seem a little odd? How did I slip through the cracks? The fact that I had the amnio and it did not check for cf really stinks. Can any one shed some light on this for me. I am really scared and worried.
