• Flexibility for moms: Stored milk lets other caregivers feed the baby, giving moms more flexibility.

Top ways to store breastmilk safely

Here are the best methods to store breastmilk, from room temperature to freezer storage.

1. Room temperature storage

• Best for: Short-term storage if you plan to feed your baby soon after pumping.
• How long it lasts: Freshly pumped breastmilk can be kept at room temperature (up to 77°F or 25°C) for about 4 hours.
• Tips: Store the milk in a clean bottle or breastmilk storage bag and avoid direct sunlight or heat.

2. Refrigerator storage

• Best for: Daily use; ideal for moms who pump regularly and plan to use the milk within a few days.
• How long it lasts: Breastmilk can be stored in the fridge at 40°F (4°C) for up to 4 days.
• Tips: Use sealed, BPA-free storage containers or breastmilk-specific bags. Place milk containers at the back of the refrigerator, where it’s coldest, and avoid storing in the door.

3. Freezer storage

• Best for: Longer-term storage, particularly for working moms or moms who pump large quantities.
• How long it lasts: Breastmilk can be stored in a freezer for up to 6 months (ideal) or up to 12 months at 0°F (-18°C) for maximum freshness.
• Tips: Use BPA-free breastmilk storage bags, and label each bag with the date. Lay bags flat to freeze for easy stacking and thawing.

4. Deep freezer storage

• Best for: Long-term storage and for preserving milk as long as possible.
• How long it lasts: In a deep freezer (at -4°F or -20°C), breastmilk can last up to 12 months.
• Tips: Keep bags organized by date to use the oldest milk first, ensuring it’s used within its safe period.

5. Breastmilk storage bags

• Best for: Convenient freezer storage, especially for on-the-go moms.
• How long it lasts: Safe according to the storage times above, depending on whether it’s at room temperature, refrigerated, or frozen.
• Tips: Avoid overfilling storage bags since milk expands when frozen. Store bags in an upright position until they’re frozen to prevent leakage.

6. Glass or plastic bottles

• Best for: Short-term storage for refrigeration or for use within a day.
• How long it lasts: Follows the same guidelines as refrigerated or room temperature storage.
• Tips: Use BPA-free plastic or glass bottles and ensure they’re securely sealed. Bottles work best for daily feeding, as they’re easier to thaw and warm.

7. Milk storage organizers

• Best for: Keeping milk bags or bottles organized by date.
• How long it lasts: Helps you follow storage guidelines by date.
• Tips: Use a milk storage organizer in the freezer to stack milk in the correct order, so the oldest milk is used first. This method ensures a first-in, first-out system, helping you avoid waste.

How to thaw stored breastmilk safely

When you’re ready to use stored breastmilk, follow these steps to thaw it safely:

1. Refrigerator thawing: Move frozen milk from the freezer to the refrigerator 12–24 hours before use. Once thawed, use it within 24 hours.
2. Warm water bath: Place the sealed bag or bottle in a bowl of warm water for a few minutes to warm the milk gradually.
3. Avoid microwaving: Microwaving breastmilk can create hot spots and destroy nutrients. Stick to gentle warming methods.

After thawing, shake the milk gently to mix any separated fat. Breastmilk should not be refrozen after thawing, as this can degrade its quality.

Essential tips for breastmilk storage success

• Label each container: Always label each bottle or bag with the date and time of pumping to track its freshness.
• Avoid refreezing: Once milk is thawed, use it within 24 hours. Refreezing can impact the milk’s taste and nutrient value.
• Rotate stock regularly: Use milk in the order it was stored to keep it fresh.
• Keep a backup supply: Storing extra milk can be helpful for emergencies, unexpected absences, or growth spurts.
