The pelvis has 2 distinct areas for birth, the area for getting in and the area for getting out.
But there is also the middle.
Three Levels of the Pelvis
Inlet for Getting In
Mid pelvis for turning
Outlet for Getting Out
Assessing progress in labor includes noting which of these three levels the baby is in. In medical terms, nurses talk about “pelvic stations” which, like train stations mark the journey. But unlike train stations, each pelvic station is associated with a level of the pelvis that moves in ways that are not much like the other stations.
-3 and -2 are at the top in the Inlet
-1, 0, +1 I call the Midpelvis based on effective solutions
+2 or lower (numbers go up) are effectively the Outlet
When providers think of techniques that “open the pelvis” they are not often associating which level that move actually opens.

The pubic arch come down each side (past the IPR noted here) to the
sitz bones or Ischial Tuberosities (IT)
and the ligaments place the coccyx (C) and sacrum’s position
Here’s what can happen when a provider doesn’t ask,
Where’s baby? but only asks the question of dilation.
A mother writes today,
“I labored for 24 hours before the C-section. I was 4 cms. and not feeling any pain when they admitted me in the hospital. I was doing squats and walking the halls until 5 cms. with no pain. The doctor thought labor was not progressing quickly enough after 7 hours and decided to break my bag of water at around 6 cms. That was when the pain shot up (More of shock than pain really). I panicked and asked for an epidural. 8 hours later and still at around 6 or 7 cms , I was wheeled into the operating room. “
One of the things I developed in Spinning Babies to ease birth and avoid unnecessary interventions to force babies through the pelvis is what I call “Pelvic Levels.”
Pelvic Levels thinking asks, Where’s baby in relation to the pelvis?
Cervical dilation is one clue. But the point is where is the wide part of baby’s head? This is where we need room. Birthing women can make room at all three levels with different moves. Opening the top closes the bottom and squatting to open the bottom closes the top. So know where baby is before expecting to open the pelvis -in the right level!
Then, when we know where baby was and where baby ended up, we can see, “Whoops!”, breaking that water bag (amniotic sac) may have dropped and locked baby into the mid pelvis. Baby’s forehead may be against one ischial spine and the back of baby’s head locked over the other side in a “deep transverse arrest” (baby’s head is stuck sideways in the narrow mid pelvis).
On our enewsletter linking you to this blog, you saw that the Spinning Babies recommended activities for any kind of a mid pelvis stall in labor:
Lay on your side with knees together and feet open and apart, but knees together!
What not to do?
Intense pelvic floor exercises or chronic gripping of the pelvic muscles (tends to add aches or shooting pains) can shorten the pelvic floor and cause a labor stall when baby gets to the mid pelvis and expects to rotate through the hole in the pelvic floor which turns out to be held tightly closed from mom’s power moves before and during pregnancy.
Soften the way by lengthening pelvic floor muscles and doing complementary exercises for the muscle pairs that nurtured together make the balance of birth.
