Abstract
This paper studies on a way of dwelling of Dual-income families with infants. Most of infants' everyday life is done in a living dinning room and the rooms connected with them (call them connected rooms). A connected room is used first as a living room, second as a bed room, and also as a store room or a children's room. Therefore the living dinning room and the connected rooms with adequate area should be made before rooms separated from the living dinning room.
