Lesson 3 shifts from theory to hands-on practice, providing participants with the essential clinical protocols and physiological considerations for managing labor and birth in water. From auscultation guidelines to water temperature, Barbara Harper outlines how to safely support laboring people in the pool—minute by minute and stage by stage.
The lesson begins with specific fetal monitoring protocols based on stage of labor, reinforcing when and how to listen to fetal heart tones, including indicators that may require exiting the water. Participants will also learn the importance of maintaining optimal water temperature, maternal hydration, and comfortable ambient conditions to support both mother and baby.
Barbara addresses the timing of immersion, affirming that there is no “right” centimeter—individual comfort and physiological signals should guide when a person enters the water. She also presents research findings, including the Cluett Study, which supports the effectiveness of water immersion in reducing labor duration and the need for interventions.
A powerful section of the lesson explores the hormonal impact of waterbirth, sometimes called the “ecstatic hormonal cocktail”—oxytocin, beta-endorphins, prolactin, and catecholamines—which contribute to pain relief, maternal bonding, and smoother labor progression.
To complete the lesson, Barbara reminds providers to “know what normal looks like,” encouraging awareness of physiological birth patterns, traditional midwifery skills, and the subtle signs of maternal wellbeing. The accompanying UK birth video serves as a visual reinforcement of clinical techniques discussed.
By the end of Lesson 3, participants will have a detailed understanding of the day-to-day clinical considerations of waterbirth, empowering them to support physiologic birth in water safely, confidently, and intuitively.
