After the baby is born for 3 ~ 4 months, the trace elements stored in the body are basically exhausted, especially the iron element. Breast milk or milk alone can no longer meet the needs of the baby's growth and development. Therefore, it is necessary to supplement some foods rich in iron. Egg yolk is one of the ideal foods. It not only contains a lot of iron, but also contains various other nutrients that children need. Easy to digest and add.

Generally, you can add egg yolk to your child in the following ways:

1. Take 1/4 ~ 1/2 cooked egg yolk, crush it with a spoon, directly add it to the boiled milk, stir it repeatedly, and feed it to the baby after the milk is slightly cold.

2. Take raw egg yolk of 1/4 ~ 1/2, add one tablespoon of milk and one tablespoon of broth, mix well, steam over low heat until solidified, and feed it to the baby with a spoon after cooling.

Gradually add egg yolk to the baby, pay attention to the baby's performance after eating, and try to feed 1/4 egg yolk first. After 3 ~ 4 days, if the child has good digestion, normal stool and no allergic phenomenon, it can be fed to 1/2, and it can be increased to 1 after observing for a period of time without discomfort.

Intake of amino acids and vitamins

Among all natural foods, almost no simple food can fully meet the overall nutritional needs of the human body, either lacking this vitamin or that mineral or amino acid. Therefore, a reasonable diet should include the consumption of a variety of foods, so that all kinds of foods complement each other and learn from each other. However, due to various conditions, this goal can not be achieved, especially the monotonous food types of babies, which is even more difficult to achieve. If you eat one or more foods for a long time, it is easy to cause the lack of some nutrients and affect your health. So you can only add some extra nutrients to your food according to your nutritional needs to supplement your physiological needs. Infant fortified food is made by supplementing any nutrients that are usually lacking. It is a common scientific product method to add the missing nutrients to the suitable foods commonly used by infants for strengthening, so as to improve the nutritional value of food. For example, rice lacks lysine. After 0.3% lysine is fortified in rice, the available protein in rice can be increased from 3.0% to 5. 1%. At present, most baby foods lack iron, calcium and vitamins A and D, so there are three products: iron fortified foods, calcium fortified foods and vitamins A and D fortified foods. Most of these nutrients are fortified in foods commonly used by babies, such as milk powder, rice flour, flour or salt. Babies get the nutrition they need by eating fortified foods, so fortified foods are good for babies. However, all kinds of nutrients have certain suitable requirements, and any excessive nutrients will have side effects, such as iron, calcium, vitamins A and D, which are toxic, so not all foods should be fortified, and the dosage of fortified foods is also limited, and the standards in different places are different. Of course, different kinds of natural foods can be used as far as possible for reasonable collocation and mutual supplement, which can also improve the nutritional value of food. For example, rice lacks lysine. If rice flour is added to the milk rich in lysine for cooking, the nutritional value will be greatly improved, and it can also strengthen food and rationally allocate physiological functions.

Supplement half the calcium you need.

Babies under 6 months need 600 mg of calcium every day, and babies over 6 months need 800 mg of calcium every day. Generally speaking, babies can only get half of the calcium they need from food (breast milk, milk, etc.). For example, all breast-fed babies eat breast milk, and every 100 ml of breast milk contains 34 mg of calcium. Even if they can eat 700 ml of breast milk every day, the calcium content is less than 250 mg. Therefore, in order to meet the normal development of baby's bones and teeth and the needs of normal metabolism of the whole body, it is necessary to supplement half of the calcium needed by the baby. So how to supplement calcium?

There are two ways to supplement calcium for infants. 1 Add calcium to infant food, such as formula milk powder, infant nutrition milk rice flour and milk wheat flour, and supplement it with calcium agent. The latter method is widely used at present. So which calcium agent is better to choose? Now there are many kinds of calcium supplements, no less than 200 kinds, and calcium supplementation has become a hot topic. When choosing calcium agent, 1 depends on the calcium content of calcium agent; 2 depends on the solubility of calcium, only water-soluble calcium can be absorbed well; 3, safety, no toxicity and no side effects; 4. The price is right. Doctors in health care units will help parents choose appropriate calcium agents according to principles. At present, a kind of "active calcium" made directly from oyster shells is not suitable for infants. Although its calcium content is high, its solubility is poor, so its absorption rate is low. Because of its strong alkalinity, it is irritating to the baby's stomach, and long-term feeding will make the baby's appetite poor. In addition, due to offshore pollution, oyster shells contain heavy metal elements harmful to health, such as lead, aluminum and mercury. Long-term use will cause cumulative poisoning. Therefore, calcium supplementation for infants should be carried out under the guidance of a doctor and should not be purchased by themselves. Don't think that expensive calcium is good calcium.

Vitamin D should be supplemented at the same time of calcium supplementation, so that calcium can be well absorbed and utilized, otherwise most of the calcium fed will be excreted by the intestine and will not play its due role.
