This section of the novel shows how, particularly in this time period, a woman’s main role in marriage was often to take care of children. Another detail that helps establish the time period is Laura’s cigarette—at the time, scientists had yet to establish a concrete link between smoking and lung cancer or dangers to pregnancy. This passage helps capture how times change, showing how for all Laura’s anxieties about being a mother, she never considers how smoking is perhaps the biggest risk to her future baby.
