Proper handling and storage of infant formula are essential for a baby’s health and safety. Following established guidelines helps prevent harmful bacteria growth, preserves nutritional quality, and supports infant development.
Prepared Formula
Once infant formula is mixed with water, its shelf life shortens, requiring prompt use or proper refrigeration. Prepared formula can remain at room temperature for up to two hours before discarding to prevent bacterial growth. If a baby begins drinking from a prepared bottle, any remaining formula must be consumed within one hour from the start of feeding. Bacteria from the baby’s saliva can enter the bottle and multiply rapidly in the warm, nutrient-rich environment.
Formula prepared in advance but not yet offered requires refrigeration for safety. Unused prepared formula can be stored in the refrigerator for up to 24 hours. Label bottles with the preparation date and time. Always refer to the specific formula brand’s instructions.
Unprepared Formula Storage
Storage guidelines for formula before mixing or opening differ by form. Unopened powdered formula remains safe until the “use by” date printed on its container. Store in a cool, dry place away from extreme temperatures. Once opened, powdered formula should be used within one month. Write the opening date on the lid.
Unopened ready-to-feed or liquid concentrate formulas last until their “use by” date. After opening, but before mixing or pouring, these liquid formulas require refrigeration and should be used within 48 hours. Cover opened containers tightly during refrigeration.
Ensuring Safe Formula Feeding
Maintain a hygienic environment during formula preparation. Wash hands thoroughly with soap and water before handling bottles or formula. Clean and sanitize the workspace and all feeding equipment regularly. Use a safe water source for mixing powdered formula; if unsure about tap water quality, boil it or use bottled water.
Formula does not require warming, but if preferred, avoid using a microwave. Microwaves create uneven heating and hot spots that can burn a baby’s mouth. Instead, place the bottle under warm running water or in a bowl of warm water, and test the temperature on your wrist before feeding.
Signs of spoiled formula include unusual smells, changes in color or consistency, or clumping. Any formula exhibiting these signs should be discarded. Never save leftover formula from a bottle after a feeding has begun, as it can harbor bacteria from the baby’s mouth. Consult a pediatrician or healthcare provider for specific concerns or questions.
