Hi all! I just recently had to explain to a friend who has just started
using her frozen bm that it is NOT sour!  She did not realize that
breastmilk is not homogenized like commercial dairy milk, and that it
would separate after it was refrigerated or frozen!!!  Please make sure
that this is not what the women are considering sour milk!  Have them
bring a sample if possible, because  it is very unlikely that frozen or
refrigerated bm would go bad! Hope this helps!
