In the beginning, human beings must rely on breast milk to survive. The original meaning of the female breast is to breastfeed, but as mammals, women only produce milk after giving birth. For the old court nurse, her own babies cried out in hunger, but her milk had to satisfy the needs of the royal children, which was contrary to motherhood, but life forced her to do so. For royal women, hiring a nurse to feed their children may have been motivated by a number of considerations.
