Children with CF tend to be smaller that other children for lots of reasons. My best advice would be to talk to your clinic and speak with the dietician there - he or she should be able to give you lots of hints about adding fat to your daughter's diet. Children with CF need more fat and protien that other children b/c even with enzymes and medicines, they still don't properly absorb all their nutrition. At 10 months old your daughter is probaly just starting table foods - I would try giving her high fat meats (beef, bolonga, ham, bacon, etc. - just be sure to cut it up really, really small). Also with your doctor's permission, peanut butter, avocadoes, ice cream, butter, cheese are all great ways to add fat to a diet. If your daughter is still using baby cereals and/or baby foods, I used to make my children's food. I would cook veggies, fruit, etc. and then put it in a blender/food processor and then add in lots and lots of formula (liquid formula) to make it smooth. The formula addds a LOT of calories and a LOT of extra vitamins. It takes some work, but I thought it was worth it. I used to make a big batch of food and then freeze it in an ice cube tray. I would then take the "frozen food cubes" and place it in a zip lock bag. That way I would have ready made food for the next week or so. I would try to make a couple of different foods each week for variety. I did the same thing with rice cereal and oatmeal - I would add in tons of formula and fruit - I just kept adding on the calories and nutrition. Remember the key is to add lots of good nutritious fat to your child's diet - my nutritionist for my son recomends adding a fat to every "good for you food" - ie. butter on the veggies, cheese on the pasta, etc.Good luck. I hope your daughter gains the weight she needs.Katrina - mother to Sean (5 w/cf), Carolyn (4 w/o cf) and Allison 2 (w/o cf)
