How Do You Store Expressed Breast Milk?

Somehow I wound up with a dozen little plastic bottles for storing expressed breast milk—I think I got them free at the hospital where I gave birth. I preferred them over those little breast milk baggies that leaked all over the place. At the time I wasn’t concerned about BPA and other toxins found in plastic; I just didn’t know much about it. Years later, new mothers are concerned about using plastic for storing breast milk—but what’s a better option? Are there glass bottles that work well for freezing milk? What do you do?
