Birth plans emerged in the 1970s-1980s as expectant parents sought more autonomy in their birthing experience. While birth plans allow parents to communicate their desired type of birth, they often read as a wish list and do not account for the unpredictable nature of childbirth. The document recommends preparing two birth plans - one outlining desired medical interventions and another focused on developing skills like breathing techniques to cope with labor regardless of unexpected circumstances. It also stresses the importance of an open and flexible mindset during the birth.
