HI there! I just wanted to give you some of my info because every case is so different. My husband and I also found out we were carriers during our third pregnancy (our first two children are negative). At 14 weeks, we went to th first of many monthly visits to the perinatologist. We declined the amnio each time because we knew we would not terminate and were afraid of a miscarriage. The ultrasounds never showed any problems, and our baby was born a healthy 9 lbs9 oz! He did not have any type of bowel obstruction. Newborn screening came back positive. We had that test (IRT levels) repeated. It was higher. So, we made the appt at th CF center where they did the sweat test. It was positive. We went back the following week where the repeated the sweat test (to b sure), did a throat culture and took a stool sample. We have been bck nealy every week. They give us something new to do each week, I would assume so we don't get overwhelmed. At 6 weeks old, we started the enzymes which we giv in applesauce before every meal. Lst week, we started to add salt to his milk. We also add formula to his breastmilk to increase the calories. Next week, they will do a chest xray and we will learn the chest physiotherapy. Our baby is a DF508 baby and has had pretty much no problems other tha acid reflux. Everything we are doing is preventative at this point. So, keep the faith. Your baby may not show symptoms even with this mutation! Good luck with everything!
