The contractions are not as intense as in squatting, but are still aided by gravity. Some women find that sitting on the toilet is most comfortable. It allows a place for the dripping of amniotic fluid, and it leaves the pelvic floor free. In addition, it allows women to relax their pelvic floor more completely because of the association of sitting on the toilet with letting go. This can be dome sitting backward on a chair, on the toilet, a bean bag chair, on a pile of pillows.
Some women also use some sort of rocking or rhythmic motion while kneeling.
This position is good for posterior babies that are causing their mothers a great deal of back labor. The swiveling of the hips can help encourage the baby to turn. This position brings the baby forward and reduces pressure on the cervix. Moving the hips through a contraction will help the woman progress to full dilation within a few contractions. Kneeling - see above.
