How does the author link birth and death in the memoir, A Life’s Work?

Cusk links birth and death throughout her memoir, suggesting that the birth of a child represents a kind of death for the mother. When her daughter is born via Cesarean section, she mentions that the room in which the surgery takes place resembles an execution chamber, and speaks of her physical self as a dead body. This imagery expresses her feelings that regardless of the joys the birth of a child brings into its mother’s life, the birth also represents a separate net loss.
