After breast milk is expressed, it can be stored for 4-6 hours if it is at room temperature around 19-26. Because breast milk itself contains antibacterial ingredients, when freshly expressed breast milk is stored at room temperature for 4-6 hours, it is no problem to give it to the child, and it will not cause infection in the child. As the ambient temperature increases, the storage time of breast milk in the ambient temperature will be shortened, for example, if it is in the hot summer, it may be less than 4 hours, and it will cause diarrhea in the child.

If the temperature is high, shorten the time that breast milk is stored at room temperature. If you need to store it for a longer period of time, it is best to keep it in the refrigerator. Breast milk can be stored for at least 3-5 days in a refrigerated environment4 days and is safe.

For some mothers who have no way to directly feed their baby's breast milk, they can only express their breast milk in advance and save it, and then feed the baby when the baby is hungry, so that the baby can absorb enough nutrients into the breast milk for some smaller babies.

Breast milk can be stored for 12 hours at room temperature between 27 and 32 degrees Celsius after 6 days after giving birth, 24 hours at 15 degrees Celsius, and 10 hours at 19 to 22 degrees Celsius.

In fact, this method of storage at room temperature is not recommended.
