Should you make a birth plan? 
My own OB told me, your birth plan should be not to write a birth plan.

These plans are not for your OBs, Midwives or Doulas, they're there for you to consider the unknowns of birth, to help you advocate with knowledge, confidence and understanding. During these planning session we will discuss Birth: options for early labour, active labour, transition, delivery and early postpartum. Postpartum: Meals, infant feeding options, sleep options, and even preparing for postpartum mood distorters. 
I offer expertise and experince to discuss tips and tricks, and challenge you to go deep to understand what might cause fears so you feel prepared in the event they happen.
