Origin: Baby Swimming http://www.swimbb.com Baby Swimming Network http://www.bbswim.net Modern nutritionists' extensive research shows that breast milk is the most perfect natural nutrient and drink for infants, providing all the nutrients an infant needs, including water and most vitamins. Although the content of calcium, phosphorus, and iron in breast milk is less than in cow's milk, the biological value of iron in breast milk is higher than in cow's milk, making it easier to absorb and utilize, with a reasonable ratio of calcium and phosphorus, also easy to absorb. Therefore, the World Health Organization requires that infants under 4 months be breastfed only without giving water or other drinks, even in hot summers, infants can obtain sufficient water from breast milk without additional supplementation. Even when mild dehydration occurs due to infant diarrhea, breastfeeding frequently by the mother is enough to correct dehydration. Only when the mother's milk is insufficient to correct dehydration, can oral rehydration salt water be given to the infant or intravenous infusion be performed while continuing breastfeeding. However, for a long time, people have been accustomed to giving water and fruit juice to infants under 4 months old, believing that this can supplement vitamins for infants, but they do not understand that this does more harm than good to infants. Because after increasing water or other drinks for infants, the amount of sucking breast milk will decrease, especially after using bottles and rubber nipples, which will further reduce the interest and desire of infants to suck breast milk, leading to a reduction in breastfeeding frequency, breasts cannot be completely emptied, thus reducing the amount of milk secretion, ultimately leading to insufficient breast milk and stopping breastfeeding. In addition, feeding water with a bottle will increase the chance of infection for infants, posing a threat to their health. In the original parenting science popularization books, it was often emphasized to add one water feeding between two milk feedings, and milk feeding should be prohibited when infants have diarrhea. But now these views are being constantly revised.
