On this topic, you may blog about an aspect of birth in a specific period of time. One of the most comprehensive books about birth in the United States is

Wertz, R.W., & Wertz, D. C. (1977). Lying-In: A history of childbirth in America. New York: The Free Press.

I have put that book on reserve for you in the Health Sciences Library at 1462 Clifton Road. There are other references in your syllabus that are useful for you if you are interested in the topic.
