Generally, the baby of 4-6 months should add fruit and vegetable juice, which is best decided according to the season and the baby's feeding method. The principle of adding is from less to more. If you are used to adding one more, you can adjust it in time to prevent your baby from being uncomfortable. You can observe the baby's urination and defecation, such as apple juice, tomatoes, pumpkins, vegetables, amaranth, carrots, oranges, pears, bananas and so on. The food is cold and hot. Red vegetables contain more iron and carrots contain more vitamin A, which is good for the eyes. Spinach should be put into water first, because oxalic acid will affect the absorption of calcium, and then use boiling water to grind mud to remove the tendons of vegetables, which contains more iron. In short, after eating, observe the urine and urine, be careful, and the baby can get better.
