Breast milk can last in the fridge at 4°C (39°F) or below for up to 4 days , but it may be acceptable to keep it for 5 to 8 days if stored under very clean conditions and kept towards the back of the fridge, which is the coldest area. It is best to aim for 4 days for safety and quality purposes.
Details on Breast Milk Storage in the Fridge
- The Academy of Breastfeeding Medicine suggests 4 days as the optimal storage time, with 5–8 days possibly acceptable in very clean and carefully stored conditions.
- Other guidelines recommend storing breast milk at the back of the fridge (not the door) and using it within 5 to 7 days.
- The CDC and Mayo Clinic recommend up to 4 days for freshly expressed breast milk in the refrigerator.
- Some practical advice from parents and other sources suggest not exceeding 4 days to avoid spoilage, though milk can sometimes be good for a bit longer depending on handling.
- Once breast milk has been thawed from frozen, it should be used within 24 hours if kept in the fridge.
Best Practices
- Store breast milk in sterilized containers or special breast milk storage bags.
- Place containers in the back of the fridge for more consistent cold temperatures.
- Label containers with the date and time expressed.
- Avoid storing breast milk in the fridge door due to temperature fluctuations.
In summary: For safety and optimal quality, breast milk can be kept in the fridge for about 4 days , but under very clean and precise storage conditions, it may last up to 8 days. It is safest to use it sooner rather than later.
