Start with a small dose of oral iron supplements and take them during or after meals to minimize gastrointestinal reactions. For nutritional deficiency anemia, increase intake of iron-rich foods such as spinach, red dates, black fungus, and duck blood. Regularly check your baby’s nutritional status and blood indicators and adjust as advised by a doctor. If your baby shows symptoms of anemia such as lethargy or lack of appetite, seek medical attention promptly.
