Child of the Nursery was an ancient Egyptian honorific title often held by high officials that were raised in the nursery alongside the Pharaoh's own children. In ancient Egypt, those growing up alongside the future king nearly always achieved high offices, since they received the best training and education from infancy on for the responsibilities they would later assume. Their tutors were thus those also educating the princes and princesses.
In the New Kingdom, the inhabitants of the nursery - where children lived as well as learned - included the sons of foreign vassals, brought to court for indoctrination into the Egyptian lifestyle, in the hope that it would inculcate a lifelong loyalty to the pharaoh once they returned to the vassal state.
