Keep the baby outdoors often. In spring and autumn, the baby can be directly exposed to the sun, and in summer, it can be placed in a cool place, so that the baby's skin is often exposed to ultraviolet rays. Ultraviolet radiation can promote the conversion of 7- dehydrocholesterol stored in skin into vitamin D3 through photochemical action. Sunlight irradiation can make the skin store vitamin D3 for later use, and it will not cause excessive vitamin D. Don't look through the glass window when you are in the sun. Ultraviolet rays in the sun rarely penetrate through the glass window. Moreover, it is necessary to expose the skin as much as possible and increase the synthesis of VD by the skin.

Second, oral calcium.

There are many preparations of calcium. Parents can choose inorganic calcium rich in calcium, such as calcium carbonate and calcium lactate, which will melt in the mouth. There is a calcium supplement set specially designed for babies, which is given to children quantitatively every day. Generally, it is taken from half a month after birth to 1 month until two and a half years old or three years old. When supplementing calcium, VD must be supplemented at the same time to promote the absorption and utilization of calcium in the intestine. Avoid putting calcium in milk, rice soup or porridge. Phytic acid in food will affect the absorption of calcium, leading to a decline in the absorption of calcium in the body. It is best to take calcium between meals, so that calcium can be better utilized by the body. Taking calcium between meals will easily affect the absorption rate of calcium.

Third, milk calcium.

Milk calcium products are extracted from pure natural milk, which does not hurt the stomach and is especially suitable for infants to absorb. Milk calcium is in the form of liquid oil. For infants under 1 year old, the tail of the capsule can be cut open and directly squeezed into the mouth of a spoon or baby bottle for the baby to lick. Babies over 3 years old can chew and eat directly. Or added to milk, fruit juice or other complementary foods, which is convenient for feeding and especially suitable for infants.

Matters needing attention

1, high calcium intake will affect the absorption of elements such as iron, zinc and magnesium.

In addition to genetic factors, a person's height must also have a sound endocrine system and the synergistic effect of vitamin D and calcium to ensure the full growth of bones. Infants and adolescents have the fastest bone growth and the largest storage of calcium, so it is necessary to ensure calcium intake. However, it is unscientific to take excessive calcium supplements and a large amount of vitamin D, which not only affects children's appetite, but also is prone to anorexia, constipation, flatulence and even stones. At the same time, too high calcium intake will also affect the absorption of iron, zinc, magnesium and other elements, especially children with anemia and zinc deficiency.

2. Babies' breast milk can meet their calcium needs within four months.

Experts remind that under normal circumstances, for babies within 4 months, the calcium produced by breast milk every day can fully meet their physiological needs. When children grow up to five or six months, they should appropriately increase complementary foods and supplement foods rich in calcium such as dairy products and bean products. /kloc-children under 0/year-old can get enough calcium for growth if the milk quantity is 800 ml per day. For those babies who eat milk instead of breast milk, it is suggested that they can take calcium supplement products under the guidance of doctors and supplement calcium appropriately.

3. Balanced nutrition and reasonable exercise ensure children's bone health.

Experts say that although the demand for calcium in pre-puberty and adolescence is greater than that in infants and preschool children, simply supplementing calcium can not significantly improve the height. Balanced nutrition and reasonable exercise are the most practical and effective ways to ensure children's bone health. In autumn when the temperature is suitable, children who are not obviously deficient in calcium can be supplemented with foods such as bean products, dairy products and fish, and children are encouraged to do more outdoor activities and cooperate with the ultraviolet rays of the sun to promote the absorption of calcium in the body, because sunbathing and outdoor sports are the best natural calcium supplements.

4. Reduce the influence of food factors on calcium supplementation.

Because food also contains many factors that affect calcium absorption and biological utilization, such as high salt content in diet or eating a lot of protein, calcium is easily lost from urine, which affects the effect of calcium supplementation. The bran of spinach, rape and grain contains a lot of oxalic acid or phytic acid, which will also affect the absorption of calcium in food. Appropriate protein, vitamin D, acidic amino acids and low-phosphorus diet in the diet can improve the absorption of calcium and promote the baby to supplement calcium.
