- Thaw and use milk within 24 hours once it has been taken from the freezer and does not refreeze.
- Check the smell and appearance of thawed milk. If it looks or smells off, it’s best to discard it.
Conclusion
In conclusion, it is indeed safe to refrigerate breast milk and subsequently freeze it for longer storage. Following proper storage practices will ensure your baby receives nutritious, safe milk. Remember that once thawed, the milk should not be refrozen and should be used within a specified timeframe to maintain quality and ensure safety. By understanding the storage process and following best practices, you can confidently manage your breast milk supply, knowing that you are providing the best for your little one.
Can you refrigerate breast milk and then freeze it later?
Yes, you can refrigerate breast milk and then freeze it later. When you store breast milk in the refrigerator, it’s important to do so within the first few hours after pumping to ensure its freshness and quality. The Centers for Disease Control and Prevention (CDC) recommends that breast milk can be stored in the refrigerator for up to four days.
If you’re planning to freeze the milk, make sure to transfer it to a freezer-safe container before putting it in the freezer. It’s best to freeze the milk as soon as possible for optimal preservation; however, refrigerating before freezing is acceptable as long as you follow the proper storage recommendations.
How long can refrigerated breast milk last before freezing?
Refrigerated breast milk can typically last for up to four days when stored properly at a temperature of 39°F (4°C) or lower. After this time, the milk may begin to spoil, leading to a decrease in nutritional quality and potential risk of bacterial growth. Thus, it’s crucial to label bottles with the date and time of pumping to keep track of freshness.
If you don’t think you’ll use the milk within this timeframe, it’s wise to freeze it earlier. Remember that freezing should take place as soon as possible for the best preservation of nutrients. Always ensure that you’re using airtight containers designed for freezing to prevent freezer burn.
Does freezing breast milk change its nutritional value?
Freezing breast milk does have some impact on its nutritional value, but it generally retains most of its essential nutrients.
