Babies with anemia were given 4 mg of iron per kg of body weight daily and 2 mg of iron per kg of body weight daily until 1 year of age after the anemia was corrected. The dose of iron taken includes the iron content in formula and food. Parents should take their babies for blood tests every 1-2 months. If the hemoglobin is below 11 g/kg, it is considered anemia and should be treated by a doctor in time. Commonly used iron supplements include iron dextrose, iron L, ferrous sulfate, ferrous fumarate, ferrous gluconate, etc. Take the medicine as ordered by the doctor and continue to take it for 6-8 weeks after the anemia is corrected. It is best to take iron between meals to reduce gastrointestinal irritation, while taking vitamin C can promote iron absorption. Some mothers often ask: “Does my baby still need to take iron supplements after taking iron-containing rice flour?” Our answer is “you still need to supplement iron, because the amount of iron in rice flour is very small, and the amount of rice flour your baby eats at one time should not be too much. In addition, some babies may have gastrointestinal reactions to iron supplements, so you can start with a small amount and gradually adapt to it. Iron supplementation is very important for the baby’s intelligent development, so it must be taken consistently. Premature babies with anemia are supplemented with 4 mg of elemental iron per kilogram of body weight per day, and 2 mg of iron per kilogram of body weight per day after the anemia is corrected.
