Breastmilk Storage Guidelines 101
Proper breastmilk storage is essential for maintaining the milk’s nutritional quality and preventing bacterial contamination. Storing breastmilk correctly ensures that your baby receives all the benefits of breastfeeding, even when feeding from a bottle. Additionally, it provides convenience and flexibility for mothers who need to return to work, travel, or manage other responsibilities.
Storage Containers
Use Clean Containers: Always use clean, BPA-free containers designed for breastmilk storage, such as glass or hard plastic bottles with tight-fitting lids, or special breastmilk storage bags.
Labeling: Clearly label each container with the date and time the milk was expressed. If your baby is in daycare or being cared for by someone else, include your baby’s name on the label.
Room Temperature
Duration: Freshly expressed breastmilk can be stored at room temperature (up to 77°F or 25°C) for up to 4 hours. If the room is cooler, it may last a bit longer, but it's generally safer to refrigerate it if it won't be used within this time frame.
Placement: Keep the milk in a shaded, cool area away from direct sunlight or heat sources.
Refrigeration
Duration: Breastmilk can be stored in the refrigerator (at 40°F or 4°C) for up to 4 days.
Placement: Store the milk in the back of the refrigerator where the temperature is most consistent. Avoid storing milk in the refrigerator door, as the temperature fluctuates when the door is opened.
Freezing
Duration: Breastmilk can be stored in the freezer (at 0°F or -18°C) for up to 6 months for best quality, and up to 12 months if necessary.
Placement: Place the milk in the back of the freezer, away from the door, to avoid temperature changes caused by opening and closing the door.
Storage Bags: Use breastmilk storage bags specifically designed for freezing. Leave some space at the top of the bag, as breastmilk expands when frozen.
Thawing and Using Stored Breastmilk
Thawing
Refrigerator: Thaw frozen breastmilk in the refrigerator overnight. It can be stored in the refrigerator for up to 24 hours after thawing.
Warm Water: For quicker thawing, place the sealed container in a bowl of warm water. Do not use hot water, as it can destroy some of the milk’s beneficial properties.
Avoid Microwave: Never thaw or heat breastmilk in a microwave. Microwaving can create hot spots that can burn your baby’s mouth and degrade the milk’s nutrients.
Using Thawed Breastmilk
Mixing: Gently swirl the container to mix the milk layers. Do not shake vigorously, as this can break down valuable components of the milk.
Temperature: Test the milk’s temperature before feeding by placing a few drops on your wrist. It should be warm, not hot.
Discarding: Discard any leftover milk that your baby does not finish within 1-2 hours. Do not refreeze thawed breastmilk.
Tips for Efficient Breastmilk Storage
Organize by Date: Always use the oldest milk first to ensure none goes to waste.
Small Portions: Store milk in small portions (2-4 ounces to start and increase based on you and your baby) to avoid wasting milk that may not be consumed in one feeding.
Pump Hygiene: Wash your hands before expressing or handling breastmilk. Clean and sterilize pump parts and storage containers after each use.
Transport: If you need to transport breastmilk, use an insulated cooler bag with ice packs to keep it cold until you can refrigerate or freeze it.
Conclusion
Proper storage of breastmilk is crucial for ensuring that your baby continues to receive all the benefits of breastmilk, even when you are apart. By following these storage guidelines and tips, you can safely store and handle breastmilk, providing your baby with safe, nutritious feedings whenever needed. If you have any specific concerns or questions about breastmilk storage, consult with a lactation consultant or healthcare provider for personalized advice.
Happy breastfeeding and storage!
