One of the most popular PBS television series of the past few years, “Call The Midwife” is based on the memoirs of Jennifer Worth, an actual London nurse-midwife. The series tells the stories of a group of dedicated, bicycle-riding midwives in a 1950’s and ‘60’s-era London neighborhood. As the episodes unfold, you come to understand how the intimate work of helping families through the natural process of pregnancy and birth knits these health care workers into the lives of their community.
