Newborns obtain the necessary moisture through breast milk and usually do not need additional water. Breast milk is rich in moisture, sufficient to meet the baby’s daily needs. Introducing water too early may make the baby feel full, thus reducing the intake of breast milk and indirectly affecting the mother’s milk production. However, in special circumstances, such as when babies sweat a lot or vomit, it is necessary to supplement with a moderate amount of water.
Nevertheless, giving newborns water improperly poses potential risks. Firstly, it may cause “water intoxication.” Excessive water can dilute the electrolytes in the blood, disrupt the balance, and in severe cases lead to seizures or even unconsciousness. Secondly, additional water can occupy the newborn’s limited stomach capacity, leading to a decrease in breast milk or formula intake, which may affect the baby’s nutritional absorption in the long term, resulting in malnutrition. Lastly, when preparing formula milk, it is essential to strictly follow the instructions; over-dilution not only reduces the nutritional value of the formula but may also increase the metabolic burden on the baby’s kidneys.
Therefore, when caring for newborns, careful consideration should be given to whether additional hydration is needed to ensure their healthy growth.
