Why is Boiling Water So Important?
If you are wondering why we advise boiling water to 100°C (212°F) and then allowing it to cool down to 70°C (158°F) to safely prepare formula you have come to the right place. Powdered formula is not sterile and can contain harmful bacteria, including Cronobacter sakazakii and Salmonella. These bacteria thrive in dry environments and are not destroyed during the manufacturing process. By boiling water to 100°C, you eliminate any bacteria or impurities that may be present in the water itself. Allowing the water to cool to 70°C ensures it is still hot enough to kill bacteria in the formula powder but not so hot that it damages the nutrients in the formula. This careful balance is essential to ensure both safety and nutritional quality for your baby. Skipping this step or using cooler water significantly increases the risk of infections that can be life-threatening for infants, especially those who are premature, under two months old, or have weakened immune systems.
