All pre-school children are assigned a small cabinet into which they can store their coats and other possessions, and in which they can sit.
These little adjoining cabinets are called CUBBIES or CUBBY HOLES

During Elizabethan times, small children were called "cubs." It was thought that for the first six weeks of life, children should not be exposed to people, sunlight or outdoor air. A small corridor-type hole was built into the wall, either in the master bedroom or in the bedroom of the caregiver of the child. The child, or cub, was kept in this "CUBBY HOLE" or "CUBBY."
