How long can you store breast milk in a bottle?

Understanding Breast Milk Storage
Storing breast milk properly is crucial for ensuring its safety and nutritional quality for your baby. The guidelines for how long breast milk can be stored vary depending on the storage method—whether at room temperature, in the refrigerator, or in the freezer.
Room Temperature Storage
Freshly pumped breast milk can be safely stored at room temperature (up to 77°F or 25°C) for a maximum of four hours. It’s important to keep the milk away from direct sunlight and heat sources to maintain its quality. If the milk has been thawed from a frozen state, it should be used within one to two hours if left at room temperature.
Refrigeration Guidelines
When it comes to refrigeration, freshly expressed breast milk can be stored in the fridge for up to four days at temperatures of 40°F (4°C) or lower. It’s advisable to place the milk in the back of the fridge, where the temperature is most consistent, rather than in the door, which can be warmer due to frequent opening.
Freezing Breast Milk
For longer storage, breast milk can be frozen. When stored at 0°F (-18°C) or below, breast milk can last for up to 12 months. However, for optimal quality, it’s recommended to use it within six months. It’s essential to use proper containers designed for freezing, such as breast milk storage bags or hard plastic containers, to prevent freezer burn and contamination.
After Feeding
Once your baby has consumed from a bottle, any leftover milk should be used within two hours. If the milk is not consumed within this timeframe, it should be discarded to prevent the risk of bacterial growth.
Conclusion
In summary, the storage duration for breast milk varies significantly based on the method used. Freshly pumped milk can be kept at room temperature for up to four hours, refrigerated for up to four days, and frozen for up to a year. Following these guidelines helps ensure that your baby receives safe and nutritious milk.
