Summer baby how to supplement calcium

Childhood due to rapid growth and development, especially bone development, so the demand for calcium significantly increased, coupled with children's gastrointestinal function is not perfect development, on the one hand may eat less, on the other hand, may be poor digestion and absorption function, which can directly lead to calcium intake and insufficient absorption of the situation, so it is recommended to routine calcium supplements for infants. The absorption of calcium needs to cooperate with the action of vitamin D. Vitamin D comes from plants (vitamin D2) and animals (vitamin D3). Human skin also contains the precursor substance of vitamin D3, which is changed into vitamin D3 after ultraviolet irradiation in sunlight, which can promote the absorption and transformation of calcium. However, the baby's normal vitamin D3 is not enough to be supplemented in the sun and diet, so in addition to proper sunbathing and diet, it is also necessary to supplement vitamin D3 normally to facilitate the absorption of calcium.

For the baby to supplement vitamin AD drops, this situation needs to be based on the actual growth and development of children, for the shape of strong, no obvious signs of calcium deficiency and normal intake of children, you can supplement the normal dose of vitamin AD; On the contrary, for children with signs of rickets, eating less or partial food, it is recommended to supplement an appropriate amount of vitamin AD under the guidance of a doctor.

The time of sunbathing is generally recommended for eight or nine in the morning or four or five in the afternoon when the light is softer. Excessive sun exposure can cause skin damage in children, with disastrous consequences, and has no obvious effect on vitamin D synthesis. At the same time, it is recommended to irradiate the skin around the anus or limbs, remember to over-irradiate the facial skin and directly irradiate the eyes. If the sun is really strong and dazzling, it is recommended that the mother take protective measures, such as opening an umbrella or applying sunscreen for the baby. In addition, it should be noted that do not be afraid of violent sunlight and sun across the glass, ultraviolet light through the glass, the beneficial components are isolated, so that the body's synthesis of vitamin D is not useful.

Under normal circumstances, there are two sources of vitamin D: one is food, and the other is its own synthesis. Vitamin D in food comes from plants (vitamin D2) or animals (vitamin D3); Human skin also contains a precursor to vitamin D3, called provitamin D3, which becomes vitamin D3 after exposure to ultraviolet light in the sun. This is the main source of vitamin D for humans. Children, especially infants, do not get enough vitamin D from food because of the few types of food they eat; Children grow fast, the need for vitamin D is relatively more; In addition, the younger the child, the less chance of exposure to ultraviolet light outdoors, so the body itself synthetic vitamin D deficiency, children prone to vitamin D deficiency, vitamin D3 in the baby body can not be normally supplemented, then it is necessary to timely additional vitamin D3 supplement, so as not to cause the baby's rickets and so on. The baby can supplement vitamin D3 after 15 days of birth to ensure that the baby's vitamin D3 nutrition is adequate. Sweat loss is mainly water and salt, so sweating more will also lead to calcium deficiency, but children with calcium deficiency will sweat more, which is not a mutual problem. The baby has more outdoor activities, mainly to add more water, appropriately add some salt, and supplement normal vitamin D3.
