Do not put breast milk in a glass because breast milk can loose its important nutrition when it's put in a glass. Use a plastic cup/container instead.
----------------------------------------
Unfortunately, there is not a lot of research about how storage containers
affect human milk. One study showed that the leukocytes in milk (the live
cells that transfer immunity from you to your baby) sticks to the side of
glass containers, but subsequent research showed greater numbers of
leukocytes in glass containers than in plastic, as the cells were released
from the sides of the containers over time. Research has also shown a loss
of antibodies and fat in milk that is stored in plastic bags, but this
information applies only to disposable plastic nurser bags, the thin ones
you can buy at most stores to use with baby bottles. If you do choose to
store your milk in these, use two bags to protect against breakage and
"freezer burn." Use twist ties to close the bags.
