So you don't drink cows milk? It's someone else's breast milk, just the "someone else" eats grass and says moo.
hmmm, sorry but I found that abit aggressive. Breastmilk is a body fluid and the drinking of other peoples body fluid such as breastmilk, urine etc does not sit comfortably with some people.

I don't go out to my backyard, kneel beneath a cow and suck on it's teat...I do, however, drink cows milk that has been pasturized to remove as many microbials as possible. When they can find an appropriate way of removing contaminates out of breastmilk (which pasturizing is not suitable because it is suggested the heating of breastmilk removes the nutrients anyway) I will consider using donated BM for my DD.

Its easy to judge people, its harder to actually try to understand why people feel the way they do....
