I respectfully disagree. Woolridge's study, as I understood it, shows
that negative pressure has nothing to do with *milk being
transferred* to the infant. (Ok, maybe not "nothing" but certainly
very, very little.)
But he's not saying that negative pressure doesn't exist. He makes a
good point of saying that if the infant is not positioned well, then
ANY amount of suckling time will cause sore nipples.
Many studies have shown that babies do indeed exert negative
pressure. The question is really about the presence or absence of
milk in the ducts. I'm hurrying to get packed and out the door to a
conference in the morning, so I can't elaborate on this, but the
basic tenet here is about the full ducts causing the baby to swallow,
which relieves the continuous negative pressure that the infant
exerts when the mother's milk ducts are relatively empty. (Yes, I
know that word "empty" is troublesome, but we don't have a better
one!)
