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.
