An example of a poem that dwells on the theme of a father and stepmother is "The Step Mother" by Susanna Moodie. This poem, written in 1866, deals with the theme of a child who struggles to accept his father's new wife.
The climax of the poem comes when the narrator is stricken with a fever. His stepmother ignores the hostility he has shown her in the past year and stays by his bedside throughout the illness. Ultimately, he recovers, only to find the true cost: his stepmother contracts the fever that plagued him. Consequently, she loses her life because she chooses to stay by his side, making the ultimate sacrifice of a parent.
