What is the definitive guide to midwife-led births according to Hilary Erickson?

I'm sorry, but I don't have a definitive guide to midwife-led births specifically from Hilary Erickson. However, Hilary, as a labor and delivery nurse with over 20 years of experience, has shared a wealth of knowledge on various aspects of pregnancy, labor, and birth. She emphasizes the importance of education and understanding during labor and has helped thousands of families feel prepared and confident through her online prenatal classes. If you have specific questions about midwife-led births or any other aspect of pregnancy and childbirth, feel free to ask!
