6 months old baby through supplementary food iron supplementation is mainly iron-containing rice flour. In addition, you can give your baby some appropriate spinach puree, fruit puree, like peaches, apples, etc. also contains the right amount of iron, while there is vitamin C inside, which can assist in the absorption of iron. You can give your 6-month-old baby a choice of rice flour with high iron content, because 6-month-old babies have relatively few complementary foods added, perhaps only 1 complementary food per day, and the relative amount is also relatively small, early only 1-2 spoons of complementary food, so it is relatively not easy to rely solely on complementary foods to supplement iron, the main source of iron or breast milk or formula containing iron. If you can’t fully achieve the effect of iron supplementation through supplemental food, you can appropriately supplement iron through medicine to avoid abnormal development of your baby due to iron deficiency. As the baby grows older, the number of complementary foods consumed increases and the amount of complementary foods increases, so it will be easier to supplement iron through complementary foods, for example, by 7-9 months of age you can eat liver puree, minced meat and egg yolk, etc. You can also choose to add some animal blood, such as duck blood, pig blood, or meat, black fungus, nori, tofu, etc., which will help your baby to supplement iron.
