I recently worked with a mother who had very bloody milk.  There were
significant breastfeeding problems so she was pumping.  The milk
gradually turned white over the next two weeks.  I had encouraged the
mom to view milk as "white blood" and she was fine with it.  The
pediatrician and ob both saw no problem with pumping/feeding this milk.
It was a good experience for me to see this first hand.  Is this what is
referred to as "rusty pipe syndrome"?
