Hello. This is my first post. My son is 6 weeks and was diagnosed just after birth through newborn screening. We have two healthy sons also. We found out we were carriers during this pregnancy, but refused an amnio due to the risks. My son really has no symptoms. He was over 9 lbs at birth and continues to be in high percentiles. No oily stools, just fussy at times. Our other two had painful gas as infants. We have started vitamins and enzymes. Can snyone tell us what to expect? I have been researchinf CF and understand it, but it is just so hard to believe he has it when he looks so good!
