 A nursery is generally designated for the smallest bedroom in the house, as a baby requires very little space until at least walking age; the premise being that the room is used almost exclusively for sleep.However, the room in many cases could remain the bedroom of the child well into his or her teenage years, or until a younger sibling is born, and the parents decide to move the older child into another larger bedroom, if one should be available.In Victorian and Edwardian times, for the wealthy and mid-tier classes, a nursery was a suite of rooms at the top of a house, including the night nursery, where the children slept, and a day nursery, where they ate and played, or a combination thereof.
