as to the discussion of breastmilk and human milk as the definitive terms,
with my editor's hat on let me say that the natural course in english is for
words that are  separate or hypenated to eventually become one word. i
personally think it would be great if we could use human milk, because we say
cow's milk, not udder milk. however, it is still so difficult to get
recognition of any of this stuff, that breastmilk might have to be it for a
while. like "formula," whew, that whole discussion again.
