For a 4-month-old exclusively breastfed infant, what is the recommended elemental iron supplementation until iron-containing foods are introduced?

• A. Elemental iron supplementation of 3 mg/kg/day for the duration of breastfeeding
• B. Monitoring the infant's hemoglobin and hematocrit at every well-baby checkup
• C. Offering iron-fortified formula to ensure adequate iron intake
• D. Elemental iron supplementation of 1 mg/kg/day until cereals are added

Answer: (D)

Breast milk provides iron, but the total amount is small and stores in a term infant start to run low by about 4 months. For exclusively breastfed infants, a small, preventive daily dose of elemental iron is the standard approach to prevent iron deficiency as solid foods are introduced. The recommended amount is 1 mg of elemental iron per kilogram of body weight each day, started around 4 months and continued until the infant regularly consumes iron-containing foods (such as iron-fortified cereals or iron-rich meats) or receives iron from other sources. Higher dosing, like 3 mg/kg/day, isn’t needed for routine prevention and can cause unnecessary side effects. Simply monitoring hemoglobin/hematocrit at every well-baby visit isn’t a substitute for preventive iron since deficiency can develop before tests would flag it. Offering iron-fortified formula would change the feeding method from exclusive breastfeeding, which isn’t the scenario described.
