The series is both educational and sensational. It demystifies the pregnancy process, but it also focuses on edge-case scenarios that are very much outside the norm.
Some of the labor/delivery reenactments feature women screaming in pain, lots of blood, and witnesses in a panic. Babies fall to the floor or into toilets when delivered; they're shown covered in blood and afterbirth and struggling to breathe. Many of the women are also in dire need of medical attention after they deliver.
There's no explicit discussion of sex, but there's lots of talk about contraception and the different ways that it can fail. Women are often shown pulling their pants off to deliver or taking their shirts off to cover the newborn, but there's no nudity.
Drinking, Drugs & Smoking
Alcohol, drugs, and smoking are discussed as they relate to the health of the baby/fetus. Some mothers-to-be drink and smoke without the knowledge that they're pregnant.
