Needing to gain weight

Ben's weight, or lack of weight gain has been a big topic among some of Ben's doctors lately. They are extremely concerned that not only has he not gained weight but lost weight the past two years. And because he struggles so much to tolerate his formula or anything different, we are limited with what we can try. We recently tried a fatty oil called MCT oil to add calories to his daily intake. After about a week on it, he started acting extremely irritable and was having bad stomach pains followed by periods of zoning out. We stopped the oil and those symptoms improved dramatically. We are now trying to increase the calories of his formula but are doing so in three stages to make it gradual and help with Ben's chances of tolerating it. Stage one has been ok so far. I'm really keeping my fingers crossed.
