La nourrice is the elderly wet nurse and nanny who raised Oscar François de Jarjayes from infancy in the Jarjayes household, and she is also the maternal grandmother of André Grandier. Her background is that of a devoted servant who took on the role of mother figure for the youngest daughter of General Jarjayes, a girl who was raised as a boy to inherit the position of commander of the Royal Guard. The nurse's personality is defined by deep affection, unwavering concern, and a gentle yet firm maternal instinct. She is a witness to the inner torments of her family and expresses a profound, constant solicitude for Oscar, whom she nurtures as if she were her own child. Her primary motivation is the protection and well‑being of Oscar and André, stemming from her bond with them and her desire to shield them from the harsh realities of the aristocratic world. In the story, she serves as a grounding, emotional anchor for Oscar, representing the warmth and stability of a humble home amid the political intrigues of Versailles. Her role is not central to the plot's action but is essential in shaping Oscar's compassionate nature and providing a safe haven. Her most important relationships are with Oscar, whom she raised and continues to care for, and with André, whom she watches over as his grandmother. Through her, the contrast between the rigid, gendered expectations of nobility and the simple, unconditional love of a caretaker is highlighted. The nurse does not undergo significant personal development over the course of the narrative; instead, she remains a steady, comforting presence whose influence is felt in Oscar's moral choices and her eventual empathy for the common people. Her notable abilities are not extraordinary in a physical sense, but consist of her deep wisdom, her intuitive understanding of human emotion, and her ability to provide solace and practical advice in times of crisis.
