Can I save a half-drank bottle of breastmilk?

Understanding the Safety of Reusing Leftover Breast Milk
When it comes to the delicate topic of reusing leftover breast milk, many parents find themselves grappling with questions about safety and best practices. The short answer is that while it is often possible to save a half-drank bottle of breast milk, there are important guidelines to consider to ensure your baby’s health.
The Basics of Breast Milk Storage
Breast milk is a precious resource, and its storage guidelines are designed to minimize the risk of bacterial contamination. According to experts, breast milk can safely sit at room temperature for up to four hours before it becomes a concern for bacterial growth, particularly after being exposed to a baby’s mouth. This means that if your baby has taken a few sips from a bottle, the milk can still be viable for a limited time.
When Is It Safe to Reuse?
The consensus among lactation experts is that leftover breast milk can be reused at the next feeding, but with some caveats. If the milk has been sitting out for less than four hours, it is generally considered safe to refrigerate and use later. However, if the milk has been left out longer than this window, it is best to discard it to avoid any potential health risks.
Best Practices for Handling Leftover Milk
1. Immediate Refrigeration: If your baby doesn’t finish a bottle, promptly refrigerate the leftover milk. This helps slow down bacterial growth.

2. Limit Time at Room Temperature: Always keep track of how long the milk has been out. If it exceeds four hours, it’s safer to throw it away.
3. Avoid Reheating Multiple Times: Once breast milk has been warmed and then cooled again, it should not be reheated multiple times. This can increase the risk of bacterial growth.
4. Use Clean Bottles: Ensure that any bottles used for feeding are clean and sterilized to minimize contamination risks.
The Bottom Line
While it is often safe to save and reuse a half-drank bottle of breast milk, parents should adhere to strict guidelines regarding time limits and cleanliness. The general recommendation is to discard any milk that has been left out for more than four hours and to always prioritize your baby’s health and safety. By following these practices, you can make the most of your breast milk while ensuring your little one remains healthy and happy.
