Check out this column by Judith A. Lothian (PhD, RN, LCCE, FACCE) in the Journal of Perinatal Education. Here's the abstract:
"In this column, the author describes the way in which the normal, natural process of labor and birth prepares both mother and baby for breastfeeding. Birth practices including induced labor, routine interventions, epidural analgesia, and separation of mother and baby disrupt the process of early breastfeeding for mother and baby. Normal, natural birth sets the stage for uncomplicated breastfeeding."
