How long is a breastmilk bottle good for after baby starts drinking?

Understanding the Shelf Life of Breastmilk in Bottles
When it comes to feeding your baby expressed breastmilk from a bottle, understanding how long that milk remains safe and nutritious after your baby starts drinking is crucial for both health and peace of mind.
Immediate Use and Time Limits
Once your baby begins drinking from a bottle, the breastmilk should ideally be consumed within two hours. This timeframe is critical because, after this period, the milk can become a breeding ground for bacteria, which can pose health risks to your infant.
Refrigeration and Storage Guidelines
If your baby does not finish the bottle within the two-hour window, you can store the remaining milk in the refrigerator. According to guidelines, leftover breastmilk can be safely refrigerated for up to 24 hours. However, it’s important to note that the milk should not be refrozen once it has been thawed or warmed.
Longer Storage Options
For parents who express milk in advance, it’s helpful to know that freshly expressed breastmilk can be stored in the refrigerator for up to four days. If you need to store it for longer, breastmilk can be frozen for about six months for optimal quality, although it can remain safe for up to 12 months in a deep freezer.
Best Practices for Safety
To ensure the safety of breastmilk, always store it in clean, sterilized bottles. Labeling the bottles with the date and time of expression can help you keep track of how long the milk has been stored. When warming refrigerated or frozen milk, do so gently—avoid using a microwave, as it can create hot spots that may scald your baby.
In summary, after your baby starts drinking from a bottle, aim to use the milk within two hours. If there are leftovers, refrigerate them for up to 24 hours, and always adhere to safe storage practices to ensure your baby receives the best nutrition possible.
