Generally, due to the rapid growth and development of the baby, improper feeding, food preference and other factors, it may lead to iron deficiency anemia in the baby. If the baby has mild anemia, it is best to breastfeed because breast milk is rich in iron, and other nutrients are also rich, and the baby is easy to absorb, so breast feeding is the best. If the conditions are not enough for breastfeeding, formula with iron added can also be used. If the baby can add complementary food after 4 or 5 months, you can also add some food materials that are rich in iron, such as liver puree, fish puree, meat puree, poultry blood and other food. Such food is very rich in iron and easy to be absorbed by the human body, so it can improve the baby's mild anemia.
