What kind of water is best for preparing newborn formula?

Generally, it is best to prepare newborn formula with warm boiled water at a temperature between 40°C and 60°C. Tap water is an acceptable water source. Specific details are as follows:

Using excessively hot water to prepare formula can destroy essential nutrients in the milk powder, making it less beneficial for the baby's nutrition. Conversely, if the water is too cool, the formula may not dissolve completely, leading to clumping, which makes it harder for the baby to digest and absorb. Warm water between 40°C and 60°C is ideal, as it helps preserve nutrients and supports gastrointestinal absorption.

For preparing newborn formula, tap water is recommended. Purified water often contains relatively high levels of bacteria and lacks minerals, while regular mineral water contains abundant minerals that are unsuitable for newborns, potentially affecting their digestive and absorptive functions and making it inappropriate for formula preparation.

It is generally recommended to breastfeed newborns whenever possible. If breast milk is insufficient or of poor quality, supplemental feeding with an appropriate amount of infant formula can be considered. Feed according to the baby's needs and avoid overfeeding. After feeding, gently pat the baby's back to help prevent spitting up.
