In exclusively breastfed infants, does routine hemoglobin/hematocrit monitoring while on iron supplementation have to be performed at every well visit?

• A. Yes, at every visit
• B. No, not routinely necessary
• C. Only if signs develop
• D. Only if formula-fed

Answer: (B)

The main idea is that healthy term infants who are exclusively breastfed and started on iron supplementation don’t need hemoglobin and hematocrit checks at every well visit. Once iron supplementation is underway and the infant is growing well without signs of illness, routine blood monitoring adds little value and can lead to unnecessary anxiety or interventions from borderline or transient lab results. Instead, rely on clinical monitoring: ensure the infant is growing appropriately, feeding well, and tolerating or adhering to the supplementation plan. Check hemoglobin/hematocrit selectively if there are signs suggestive of anemia—such as pallor, unusually fast heart rate, fatigue, or poor feeding—or if there are risk factors that raise the likelihood of iron deficiency (for example, very preterm birth, low birth weight, inadequate supplementation, or chronic illness). If no symptoms or risk factors are present, routine testing at every visit isn’t necessary.
