my 6 months old son is always kinda constipated....it is nothing painful but he goes to the "bathroom" several times a day and all he does each time is a small " hard ball" of poop....I wonder if he is taking too much enzimes? Or, is it normal to cf babies to be constipated??Should I change his diet ( now it is almost 100% breast milk)???val(mum of torin W/ CF 1/2 year)
