The thing that gets me with these milk banks/donation facilities is they always pastorize the milk. How is the child suppose to have any of the natural nutrients if they kill all the natural immunity building bacteria in the breast milk? I mean it's finally come out more recently that breast milk can be left out a lot longer than they use to tell you and be perfectly safe (because the milk itself is antimicrobial to some extent). It's simply the catching containers that can be contaminated.
