No, she does not need it if she doesn't like it. Try regular oatmeal or malt o meal or giving other foods with iron. So sad that the baby food industry makes everyone think that babies NEED their products. I usually used baby cereal just to thicken some foods I made (or jar foods) when they were a little too thin. Don't know if you made it with breastmilk or formula but that's an idea. As long as she gets her iron from somewhere else it's not necessary.
