How does the author metaphorically explore the ways in which love and fear inform one another in the novel, Want?

Elizabeth, her mother, Sasha, Kayla's mom, and the rich woman all describe their experiences of longing for, carrying, losing, giving birth to, or caring for babies via allusions to terror or trepidation. Elizabeth and Sasha both worry they will hurt their children or fail to provide for them. Elizabeth's mother worries her daughter is unfit to raise her grandchildren, or that she will endanger herself. Kayla's mom also worries about her daughter's safety and wellbeing, fearing that Elizabeth is trying to intrude upon her role. The rich woman who wants to buy Elizabeth's husband's sperm is terrified of the emptiness she feels while longing for motherhood. All of these dynamics allow the author to metaphorically explore the ways in which love and fear inform one another.
