My 5 month old DS has reflux and has been on Infant Gaviscon for about a week. He also started on solids three days ago (just a spoon full of baby rice in the morning). He seems to be very constipated. He just squeezed out his first solid poo but was crying in pain and had a lot of trouble getting it out and it had blood on it. I hear Gaviscon can cause constipation but think maybe he may need some water in his diet now that he's on solids. He's completely breast fed otherwise. Does anyone have any advice about easing constipation or ideas for alternatives for reflux?
