According to the article, iron in breast milk is easily absorbed by the child. If you are worried about your child not getting enough iron, you can try cooking more of the food that are rich in iron (these is a list in the article, examples are sweet potato, green vegetables like spinach and watercress, grains like brown rice, millet, and quinoa, tofu, dried fruits etc). Couple such food with other baby food high in vitamin C will aid in the absorption. The article also provides a table with the normal iron levels for children of various age groups.
I would suggest that if you are very concerned about this, arrange for your child to get a test to find out her iron level (after weaning from breast milk) and seek the doctor’s take on whether iron supplementation is required.
Hope this helps!
