Elisheva, Thanks for the info on circs. Now onto A & P.  My understanding
is that the fat globules cling to the inside of the aveolar cells.  With
release of oxytocin the cells squeeze and push the fat cells out into the
ducts.  Breast compression possibly helps with stripping the fat out of
these cells.  It does increase volume taken with very little work on baby's
part. Foremilk is present in the sinuses when feeding starts.  Let down
causes the fat to move into the ducts and more milk is produced while baby
is nursing.  There are probably many little let downs that aren't even
perceived by mom, that keep pushing fat cells out. I think I've read that
approximately 30 % of milk is present when baby starts to feed and more is
made "on demand".  It is a very complex and wonderful system.  Sincerely,
Pat in SNJ
