Vulnerability in birth: A negative capability.

An explanatory framework is offered to clinicians that could increase their awareness of sociocultural and historical factors impacting a woman's expectations for birth. Appreciation of the woman's vulnerability in birth, exposing her to the influence of this framework, can assist clinicians to facilitate a quality birth experience for women. Furthermore, supporting women and midwives to accept this experience of birth vulnerability as a "negative capability," can facilitate an empowering birth experience.
