Doulas are shown to lower the C-section rate by 40%, primarily by preparing individuals for birth. They focus on optimizing the baby's position before labor and guiding parents through various positions and movements during labor to enhance comfort, manage breathing, and relax the pelvic floor. Doulas also navigate the hospital system, assisting parents in making informed decisions, asking relevant questions, and fostering a sense of safety. This comprehensive support often contributes to a higher likelihood of vaginal births, leading to positive birth experiences and recovery.
