Preparing formula for your baby is an important task. Boiling water, for formula, is one of the necessary steps in the process to ensure that your baby’s formula is safe and free from bacteria. While boiling water isn’t always necessary, it can be a good idea to do so when making formula for your little one. Boiling water helps to kill any potential bacteria that may be present in the water, ensuring that your baby’s formula is as safe and healthy as possible.
