How long does breastmilk last after unfreezing it?

Understanding the Lifespan of Unfrozen Breast Milk
When it comes to the delicate process of feeding infants, the safety and quality of breast milk are paramount. For parents who store breast milk in advance, knowing how long it lasts after unfreezing is crucial for ensuring their baby’s health.
Duration After Unfreezing
Once breast milk has been thawed from the freezer, it is important to handle it properly to maintain its safety. According to guidelines, unfrozen breast milk can be safely stored in the refrigerator for up to 24 hours. This timeframe allows parents to prepare for feedings without the need to rush, ensuring that the milk remains safe for their little one.
If the thawed breast milk is left at room temperature, it should ideally be consumed within two hours. Beyond this period, the risk of bacterial growth increases, making it unsafe for consumption. Therefore, if you plan to use thawed milk, it’s best to keep track of the time to avoid any health risks for your baby.
Warming and Reusing Breast Milk
For those who warm breast milk after thawing, it’s essential to note that warmed milk should not be refrozen. Once warmed, breast milk can be kept at room temperature for up to four hours. However, any leftover milk that has been warmed should be discarded after this period to ensure safety.
Best Practices for Storage
To maximize the quality and safety of breast milk, parents should adhere to best practices for storage. This includes using clean containers specifically designed for breast milk, labeling them with dates, and ensuring that the milk is thawed in the refrigerator rather than at room temperature. These steps help maintain the nutritional integrity of the milk while minimizing the risk of contamination.
In summary, after unfreezing, breast milk can last 24 hours in the refrigerator and two hours at room temperature. Following these guidelines not only ensures the safety of the milk but also supports the health and well-being of infants.
