Nowadays, many media and various news reports advocate that babies should supplement various trace elements from an early age, but in fact this is completely unnecessary. You know, in ancient times, human nutrition could not be compared with modern people at all, but children could still grow normally at that time, and the nutrients absorbed in the body could completely meet the needs of children's growth and development.
Breast milk is the most suitable nutrition for human infants. For most children, breast milk can provide all the nutrients that formula milk powder and all other foods can't replace.
Some time ago, I specially consulted a dietitian, and they told me that in fact, children just need to supplement a little vitamin D now, because according to the current dermatology, the baby's skin is very fragile before the age of three, so it is not recommended that children be exposed to too much sunlight, but if they do not receive ultraviolet radiation directly, the vitamin D synthesized in the human body will be insufficient, and the deficiency of VD will lead to calcium deficiency in some children, similar to breast milk.
At the same time, the doctor also advised me not to supplement some nutrients to my child too much, because this will affect the normal metabolism of trace elements in the child's body, but it will cause some troubles for his growth.
Therefore, we should try our best to insist on breastfeeding and buy appropriate vitamin D products, which can help children develop and grow well.
