【相关描述】A doula supports a woman and her family in achieving the kind of birth that they desire. A doula works in homes, hospitals, and birth centers; and gives, emotional, physical, and informational support. A careprovider, be he/she a midwife, OB/gyn, or family practitioner, will take care of a woman's prenatal care and birth. A doula is supposed to ensure that someone is always available to look after the mother-to-be emotionally. These objectives are facilitated by communication between the laboring woman, her partner, and her clinical care providers.
As a supportive companion (other than a friend or loved one) a doula is professionally trained to provide birth-labor support. She performs no clinical tasks. A doula also refers to lay women who are trained or experienced in providing postpartum care—mother and newborn care, breastfeeding support and advice, cooking, child care, errands, and light cleaning—for the family. To distinguish between the two types of doulas, one may refer to "birth doulas" and "postpartum doulas".
