So we had a scare. But all ends well.    This episode is in two parts. First, you'll hear directly from my amazing wife about giving birth in our family car. It's a crazy story. Then, I speak with Dr. Luc de Bernis Senior Maternal Health Advisor at the UN Population Fund who puts our experience in a larger global health context. We discuss various interventions to reduce maternal and newborn mortality around the world, including the deployment of what the World Health Organization calls "Skilled Birth Attendants."     I've reported on health systems and maternal and new born health for years and visited clinics and hospitals in Bangladesh and several countries in sub-saharan Africa, but it wasn't until my wife gave birth in our old car that I truly appreciated the role of a skilled birth attendant in ensuring the safety and health of mother and child.
