In brief: Fridge or freezer
Breastmilk can be stored in the refrigerator for several days and in the freezer for 3-4 months.
The white blood cells in the milk die in the freezer lessening the milk's anti-infective properties slightly so if you're pumping at work for the next day's use, store the milk in sterile bags or bottles in the fridge. But if you're not sure when it will get used it's best to store it in the freezer.

Using glass will cause more cells to stick to the bottle, less in the milk. Sterile bags are better!

In brief: Freeze it!
Breast milk should be stored in sterile plastic bags or containers, about 2 oz at a time.
It can be frozen and stored for several months. Label the bag with the date. It can also be kept in the refrigerator if it will be used within 48 hours. Remember, when you defrost the milk, do not put it in the microwave! this can cause hot spots and may destroy some of the milks nutrients.
