I have a friend in Cali who is a Doula, this is from her website:
****************************************
What is a Doula?
From The New Oxford American Dictionary:
doula |ˈdoōlə|
noun
a person, usually a woman, who is professionally trained to assist a woman during childbirth and who may provide support to the family after the baby is born.
From Doulas Of North America (http://www.dona.org)
"A birth doula...
...recognizes birth as a key life experience that the mother will remember all her life...
...understands the physiology of birth and the emotional needs of a woman in labor...
...assists the woman and her partner in preparing for and carrying out their plans for the birth...
...stays by the side of the laboring woman throughout the entire labor...
...provides emotional support, physical comfort measures, an objective viewpoint, and assistance to the woman in getting the information she needs to make good decisions...
...facilitates communication between the laboring woman, her partner, and clinical care providers...
...perceives her role as one who nurtures and protects the woman's memory of her birth experience."
How Can a Doula Help You?
Having an excellent support team is essential to a fulfilling birth. This team consists of the birthing mother, her medical care provider(s), and can also include the mother's partner, family, and/or close friends.
A Doula is a separate member of the team, brought in to provide constant, objective support to the woman during her late pregnancy, labor, and delivery. Rather than replacing the other members of the support team, the doula works with them to provide both mental and physical comfort to the mother. She does this through the use of breathing exercises, massage, visualizations, and other stress reduction techniques, as well as a constant outpour of support for the woman giving birth.
Additionally, the doula serves as an information and reference bank for the pregnant woman, providing explanations of common situations in childbirth, medical complications, and possible interventions in order for the mother to make informed decisions about her own care.
A doula is a non-medical professional, meaning that she can provide emotional and physical support, however she is not qualified to partake in clinical tasks such as examinations, or the prescription of treatment. She will, however, work as an advocate on the mother's behalf, supporting the mother's choices as well as empowering her to communicate her wishes with her health providers, by way of a flexible birth plan.
Having a doula can be an excellent choice for any mother, regardless of the extent of her support team already in place. Because of the support received from a doula, a woman is less likely to request an epidural or other pain medication, and is less likely to require birth by vacuum or forceps, or birth by cesarean.
Having a doula can increase the likelihood that a woman will feel satisfied with her birth, have a better maternal-infant interaction, and experience less postpartum depression.
Although every birth has the potential for complications, several studies* suggest that the presence of a doula can significantly lower these complications and the necessity for medical interventions.
