Yulanda asks, where are the milk reservoirs that the baby's gums compress
whilst feeding?  (Answer: They aren't there because Hartmann questions their
very existence.)
I ask, where are those spongy yellow bunches-of-grapelike things
representing the milk glands as shown in the old Childbirth Graphics cloth
model?  Would that be fatty tissue around the milk-producing glands in
Hartmann's version?  According to Hartmann, the ropy things we've all been
palpating seem to be glandular tissue.  The milk ducts would be scarcely
palpable with the fingers in his version.  A challenging notion, but not
impossible to believe, and not incompatible with, say, RPS.

What still baffles me is how the drawings produced by examining cadavers can
be so drastically different from Hartmann's portrayal of the breast tissue.
Have previous anatomists missed the mark so completely, thinking that
adipose tissue is glandular, and glandular is ductal, and not seeing the
actual ducts at all?  What about those who injected molten wax into the
ducts, supposedly finding the reservoirs that way?  Were they actually
finding the glands, which are not as discrete from the ducts as we have
thought, based on the grape-like alveoli and the tube-like duct model?  This
is very interesting indeed.

I am among those who finds Medela's involvement in Hartmann's research a
drawback.  The fact that their pump technology is so closely linked to this
anatomical paradigm is a barrier to my believing in it with all my heart.  I
have been totally turned off after seeing the model presented as a prelude
in The Medela Symphony... As though the primary purpose of the research was
to show that Medela's pumps are better than anyone else's, and not to
illuminate the anatomy and mechanisms of breastfeeding.  I don't have any
objection to Medela's pumps per se, and indeed, I recommend them often
enough, but I don't yet believe they, or the Perth team, have a corner on
the One True Way to understand the lactating breast.
