I also have a 5 year old with CF who just started school. Does he eat lunch there or just a snack? Either way, it is a great way to really feed him without having to worry about his brother. Sean just eats a snack at school so I am trying to give him one salty/fattening item and one healthy item. Today he had corn chips and grapes. He also has had cookies and apples; cheese crackers and oranges; pudding and juice, etc. If you have or buy those blue ice things, you can pack almost anything in their lunch boxes/snack bags without them spoiling. Sean really loves ham and cheese rolls ups (ie. ham slices rolled up with American cheese which might appeal to your son if he doesn't like bread). Regarding his brother, Sean also has two younger sisters who I need to be careful of regarding portions and fat intake. We carefully have explained to my older daughter (who will be four on Sunday) that loving children means doing the best thing for them. We explain that with Sean's CF the best thing for him is to eat lots of fats, so he has to eat more chips, ice cream, pudding, etc. We do that for him because we love him and want him to be healthy. Then we explain that it is okay for people who don't have CF to eat a little bit of fats, but not alot. I tell her that I am just like her and also can not eat all the things that Sean does. We tell her that we would love to be able to eat all the ice cream, cookies, etc. that we want but it wouldn't be healthy. We love ourselves and we love her and we have to do what is best for her and us. It works better than we ever thought. I think Carolyn cried a little bit the first time she saw Sean with a larger bowl of ice cream, but now she understands and actually tells people. She will look friends directly in the eye and say "My brother Sean has CF and he needs enzymes before he eats and sometimes he has to eat more chips than me but thats because lots of chips are good for him and only a little bit of chips are good for me." Kids are A LOT smarter than we ever think - if you tell them honestly and with lots of love, you can pretty much talk to them about anything. We really felt that this was important b/c it will be a big part of the rest of our lives. We feel strongly that we don't want our children equating food with love. However, this is not to say that it is easy. Keeping our daughter feeling loved, happy and well-adjusted is defintely a huge unexpected struggle regarding CF in our lives. For this reason, I sneak in a few "extra things" into Sean's meals that they can't see. Sean gets a whole lot of butter on his veggies (ie. I'll give him two or three Tablespoons with each portion) b/c it is a great way for him to get vitamins and fat, plus you really can't see melted butter and I add half-and-half into his milk. I'll also add in things like more cheese and more. If they ask me, I'll tell them honestly what I did, but this way it isn't always "in my daughter's face" that Sean gets "more food/fat" than his sisters.Good luck with meals and food. I hope your son has a great year at school.Katrina --mother of Sean (5) w/cf and just started K, Carolyn (who will be 4 on Sunday) w/o cf, and Allison (2) w/o cf
