"During the birthing process, as a soon-to-be-born baby passes through the
birth canal, some of the fluid inside the baby's lungs is "squeezed" out.
After
birth, during the first breaths that a newborn takes, the lungs fill with
air and more fluid is pushed out of the lungs. Any remaining fluid is then
coughed out or gradually absorbed into the body through the bloodstream.
In infants with TTN, however, there is extra fluid present in the lungs or
the fluid in the lungs is absorbed too slowly. As a result, it is more
difficult for the baby to take in oxygen properly, and she breathes faster
and harder
to compensate. TTN is also called "wet lungs" or type II respiratory
distress syndrome."

Wherever this comes from, it is very old and not correct. Perhaps they were
trying to explain something very complex in simplistic terms for the lay
person. As I said, I USED to say this as well. It is not the cesarean that is the
problem. It is the lack of the chemical changes that precede and accompany
normal labor. There also appears to be some genetic component to lung water
clearance.
