Our son had his g tube at 8 months of age and he weighed about 12 lbs. at the time. He was gaining, but very little. We had tried concentrating his formula to very high calorie, but that is about the only "food" type of strategy we tried. He just really would not eat enough and he was not even coming close to being on the growth curve ( I think he had actually fallen off of "his" curve), so that is when they suggested we do the g tube. He is pancreatic insufficient but I don't know the exact values from his stool samples. Hope that helps.
