Has your Dr. given you any information more specific than anemia? There are different kinds of anemia. Most people think of an iron deficiency when they hear anemia, but this isn't always the case.
When I was a child, my doctors thought I had extremely low iron, and treated me accordingly. However, as an adult I discovered that I have a very specific type of anemia that was acquired genetically (neither of my parents knew they were a carrier). However, it is not an iron deficiency...all the iron in the world would not make (and never has) a difference. It doesn't usually effect my health or lifestyle. Usually it is only an issue when a doctor runs general blood tests for some reason and some of my numbers come back looking weird...when I tell them I have the specific anemia that I have, they say oh, it's okay then. The only time it has effected me was when I had my daughter, I ended up needing a blood transfusion.
I know there are quite a few different types of anemia. You would need more info about your daughter's to know what if anything you should be doing differently for her.
