I would advise to just be patient. This trend is seen over and over with Exjade. The iron stored in organs and body tissue will be removed first and then ferritin will drop. I don't think combination chelation is needed yet and am hesitant to suggest it at her age. If ferritin remains high at age 6, then combination with desferal might be considered, but I think waiting is best. Iron stored in ferritin can't damage the body, but iron in tissue does, so removing that is most important.
