Improve your odds. Having a doula is no guarantee of achieving a natural birth, but a large body of research shows those with doulas are less likely to require pain meds/anesthesia or need a c-section, forceps or vacuum extraction, so I highly recommend a doula (or friend who will act as a doula) to all women giving birth. See http://www. Dona. Org/resources/research. Php for references to the research if interested.
