Never add the formula powder before the water. The correct method is to pour the appropriate amount of warm water (40℃～60℃) into the bottle first, and then add the formula powder in the correct proportion. It is best to prepare it fresh and feed it immediately to avoid contamination.
Never re-boil prepared formula. Re-boiling prepared formula will alter the structure of nutrients such as proteins and vitamins, causing them to lose their original nutritional value.
Never increase the concentration of formula or add supplements on your own. Doing so will increase the burden on the baby's intestines, leading to digestive disorders, constipation, or diarrhea. In severe cases, it can lead to necrotizing enterocolitis. Additionally, when a baby is ill and needs medication, parents must not mix the medicine into the formula. No additional water is needed when feeding formula, as long as it is prepared correctly according to the proportions. Under normal circumstances, a baby will not experience symptoms like "heatiness" from the formula.
How to prepare formula for your baby? Pay close attention to the water temperature and the proportions when mixing the formula.
