Breastmilk should be stored at a temperature and for a period of time, preferably below 4 degrees Celsius and for no more than 72 hours. If it is not possible to refrigerate it below four degrees Celsius then try not to store it for more than 24 hours, and if it is left at room temperature then try not to store it for more than three hours. If you need to store it for a long time, it is recommended to use special milk storage bags and put it in the freezer.
