Hello All: I have searched the archives and found just a bit, will try again, but would also appreciate responses from any who have experience in this area. Local mom has 2 kids now w/CF, 1st was not diagnosed til 6 months, had been bfdg exclusively up until then(and was quite healthy), was weaned (at HCP's suggestion), put on formula, and was sick, sick, sick, for the next several years. New baby is several weeks old, breastfeeds beautifully, mom wants any info/ research that supports breastfeeding in her situation. TIA from Martha Johnson RN IBCLC
