How to deal with anemia in a 43-day-old baby?

Patient's question:

Baby has only been born for a little over a month. Because he hasn't gained much weight, I took him to the hospital for a check-up. The doctor said it might be caused by anemia, but the baby is still so small. I want to ask if anemia in a one-month-old infant

Doctor's answer:

Generally, it is important to consider that not taking calcium supplements during pregnancy may lead to nutritional deficiencies. Since neonatal hemolytic disease often combines with anemia, and physiological anemia can also occur, as long as it does not fall below 95g/L, it is acceptable. Physiological anemia is a normal phenomenon during the growth and development of infants, so no treatment is necessary. However, it is essential to ensure that the food provided is rich in substances needed for hematopoiesis, such as breastfeeding as much as possible and giving formula milk suitable for the infant's age. It is recommended that you consult a doctor for detailed advice.
