Breast milk is naturally iron-rich and absorbable, formula is fortified with iron, but cow's milk blocks your toddler's ability to absorb the iron that does exist in her diet.\n\nThe sources provided don't specify the exact daily iron requirement for an 18-month-old drinking cow's milk, so you'll want to ask your pediatrician for the specific dose and form that works best for her age and weight. What matters most is pairing whatever iron supplement you choose with vitamin C—foods like citrus, berries, or tomatoes at the same meal will help her body actually use it.","sources":"[{\"pmid\":\"39599621\",\"title\":\"A Systematic Review of Isotopically Measured Iron Absorption in Infants and Children Under 2 Years.\",\"journal\":\"Nutrients\",\"year\":\"2024\",\"url\":\"https://pubmed.ncbi.nlm.nih.gov/39599621/\",\"score\":0.81}]","thread_json":null,"topic":"nutrition-and-iron","view_count":0,"created_at":"2026-08-29T16:00:53.785Z"}
