My baby has been having various feeding problems since birth. I finally took him to a paediatric gastroenterologist last week who put him on Enfamil O-Lac (lactose free formula). This seems to have solved the feeding problems, but he is now really constipated to the extent that he bleeds a little when he poos because it's so hard.
What should I do? Will he settle down on this formula, or should I look for an alternative. He seems much happier on the lactose free formula, but I am worried about his poos being quite so hard.
