The goal of this randomized trial is to test if changing a person's position in labor can increase the chances of delivering their baby vaginally.
Specifically, it aims to answer the questions:
* In fetuses who are facing upwards (occiput posterior, OP) or sideways (occiput transverse, OT) during labor, does changing the patient's position during active labor to a side-lying posture with a peanut ball increase the chances of them having a successful, spontaneous vaginal delivery? * Does changing the patient's position in active labor affect the position of the baby at the time of delivery? * Do intentional position changes in labor impact patient-perceived autonomy during their labor and delivery experience?
Participants will:
* Receive an ultrasound during labor to determine the position of their baby * Be asked to adopt a specific position in labor (side-lying with peanut ball) if they are randomized to the study group * Receive additional ultrasounds during labor to assess their baby's position * Fill out a questionnaire about their labor experience following the delivery of their baby
