"This means that most of the births they have seen were to women on epidurals lying still during labor, waiting for it all to be over. Seeing this kind of birth over and over again causes a subconscious imprint on the mind, and many women develop enough fear of the pains of childbirth that they block the messages their bodies give them about other positions they might take in labor. Others may simply fear diverging from the norm. A woman in the first stage of labor may find it beneficial to try several upright positions: standing, perhaps leaning on a counter or tray table; slow dancing with her partner; sitting while leaning forward or propped up with pillows; squatting; or sitting in a rocking chair. Sometimes one position suffices, but laboring women usually like to change from one position to another as labor progresses. One of the most effective labors I ever witnessed was that of a first-time mother giving birth to a very large baby. She moved through the first part of labor very efficiently by belly-dancing while putting as much of her weight as possible on a long staff she was holding to steady herself. She then pushed her baby out while leaning on the bed in a kneeling position. A woman's position during labor and birth may affect her ability to breastfeed in a couple of ways. Dr. Roberto Caldeyro-Barcia, an Uruguayan obstetrician, was one of the first to scientifically investigate the effects of maternal position on labor. In 1979 he published a study now regarded as a classic, which demonstrated that mothers in a "vertical" position had thirty-six percent shorter opening stages of labor than "horizontal" women; the "vertical" women also reported less pain than the "horizontals." Walking helped labor progress as well, because it brought the pressure of the baby's head against the cervix, helping it to thin and open. And the "vertical" mothers' babies' heads were less apt to be extremely molded just after birth, indicating a somewhat smoother passage through the mother's birth canal. Equally important, the babies of women who gave birth in upright positions had less fetal distress at birth.5 These factors all increase the chances that a woman will have a good early breastfeeding experience.
