Oh, I also wanted to share about the "belly lift" technique again, too.
The belly lift is designed for use with back labor. Back labor is not only caused by a posterior baby, it can also be caused by having a short torso comparataive to the size of the baby, which puts more pressure on the tailbone.
Pressure on the tailbone is painful-- always. It is different than the regular pressure of the ideal contraction, which places pressure around the belly and pushign down onto the cervix.
By removing the pressure from the tailbone you can make birth much mroe enjoyable and comfortable, even pleasurable. Also, when the pressure is pushing down on the cervix, as opposed to the tailbone, you dilate faster and the baby comes down the canal more easily, quickly, gently and comfortably.
So positioning is important. Try to get your baby into an anterior postion-- back facing out or slightly towards the side.
But for some women, specifically short women or women with a short rise, there can STILL be pressure on the tailbone even when baby is anterior.
So for those women with stubbornly posterior babies, and for those women who are short, the belly lift brings relief and a quicker, easier labor.
To perform the belly lift, when having a contraction, simply lock your hands together underneath your belly and gently walk your hands out and up, lifting your belly up and in. You can feel the baby's head line up over the cervix, and you should be able to feel the point of pressure change from over the tailbone to over the cervix. You are NOT pushing the baby down at all, just changing the way the baby is lined up, and letting the contraction push down.
If this doesn't make sense, the book "Back Labor No More" explains the belly lift in excruciating detail.
A warning: The belly lift really does make labor faster and easier.
Some women who perform even just ONE belly lift give birth immediately-- within a few minutes. There are several accounts of women performing a belly lift at home and then trying to get to the hospital only to give birth in the car or the parking lot. So unless you are planning a homebirth or prepared for a homebirth, I would avoid doing the belly lift at home. Otherwise, lift away, any time past 37 weeks!
