It is completely understandable to feel concerned, but we can safely get this on track. Pediatric iron drops are highly concentrated, allowing for more precise dosing than syrups for infants. This new dosage can be very effective, but it must be exactly tailored to your baby's current weight by your pediatrician. To boost absorption, avoid giving the drops with milk or formula, as calcium blocks iron uptake. Instead, give them between feeds. Since the hemoglobin dropped despite previous therapy, please consult your doctor to rule out underlying absorption issues. A simple repeat blood test in a few weeks will ensure your baby is responding well.
