All my life I have been skinny, all my life I have tried to gain weight. Even when I was pregnant I gained only 15 pounds and after the baby came out, the nurses said I didn't even look as if I had been pregnant. I breastfeed and have to eat constantly just to maintain my weight. I am 5'4'' and weigh 115lbs. I eat a lot of high calorie foods, I drink milk, eat lots of bread, grains fruits and vegetables. I just don't know what else I can do. I am not one of those who will eat junk either, because that will give you the unhealthy weight. Any advice?
