Hello, I sit reading your post its like you are talking about my life. I have twin boys with CF and what a road we have been on with the food and calorie issues. Our boys are tweleve and they only weight around 62 pounds. We have been through the stimulants which did make them so sleepy. We have done Growth Hormone shots with no luck and we have had a g-tube which was a total nightmare. I know some CF Families have had the tubes and loved them but our experience with the gastro doctor was something I will never get over. They no longer have the tubes which by the way only added about two pounds after we fed them case after case of formula. We are still in the same boat. They are still no bigger. They went to middle school this year and they look like third graders compared. I am at my wits end on what to do next. We try to make all their food with extra calories (which it seems has only affected my husband and I) causing us to have to diet. They are picky on top of things. Does anyone out there have any suggestions? Any help would be greatly appreciated.
