Hi Chrissy,
My daughter has been diagnosed with beta-thal-major and as I had posted earlier has started blood transfusion, at two months of age. We met with Dr. Ellis Neufeld at the Boston Children's Hospital last week. I had asked him about the iron in the formula and he indicated that we should switch to the low-iron formula, but he indicated that the iron from food is negligible as compared to what my daughter is going to get through her transfusions.
Also, he was of the opinion that since infants need the iron for their normal growth and development, and they tend to use up a lot of iron during their growth spurts, it is not advisable to wean them off the formula with iron (use formula with low iron instead).
Hope this helps.
