Doulas
Birth Doulas advise on birthing techniques and serve as the mother's advocate during labor. Postpartum doulas assist with emotional and physical recovery from childbirth and teach coping skills to new parents. You don't need a college degree to become a doula, but to be competitive in the field you should be certified by Doulas of North America (http://www.dona.org/). The median fee for a birth doula is $700 per birth.
How to get a jump-start: Get to know established midwives and doulas in your area and ask if you can witness a birth or postpartum counseling session to see if the field's for you.
