"Spoely,
Loved the Perry Stone stuff.
I am a nurse midwife and I can tell you that in the comparison to
labor the change in
centimeters dilation of the cervix is also as he said about the
time--"compressed."
Most of the length of labor is used to get through the first six
to seven centimeters and the last three tofours centimeter go more
quickly because although the contractions slow down a little
(theycharacteristicly come in pairs or triplets and then there is
pause) they are much stronger. And the work of thesecontractions
that accomplish the last two to three centimeter dilation also cause
the dramaticchange in station. Station is the measure of the
fetus being pushed down in the pelvis known as the 'decent'".
