If a woman  has
shorter nipples with less connective tissue and/or muscle in the  nipple
button itself, combined with shallow sinuses, I envision that she  would
tend to leak more easily. In fact, I believe that is the explanation  for
some mothers I have seen that find leakage a problem in the  last
trimester of pregnancy. It doesn't take much stimulation of say, a  sheet
rubbing across the nipples, or a mild Braxton Hicks contraction to  elicit
a mild MER and start them leaking. I have counseled them that  wearing a
soft sleep bra seems to reduce the tendency by muting the  stimulation.


Dear Friends:
    As always, I am amazed with Jean's breadth of  knowledge and thought 
regarding anatomy and physiology.
    What about the primalacta, who leaks with a first  baby during the early 
postpartum, and not with subsequent babies? Is there some  structure that 
learns or modifies during the course of subsequent  lactations?
    For some reason, I am reminded of whales whose  MER pumps the baby full 
very quickly. Not that we could ever study whale  nipples.
    Other nipple trivia: manatees have nipples in their  armpits; mamma 
manatees that are rescued by being roped under their flippers  sustain nipple 
damage.
    warmly,
