A playpen is a small enclosed space for a baby or a very small child to play in, so they can move about without wandering off or falling down the stairs. It is like an open box: the floor is the floor, and the sides are bars, mesh, or a net, high enough that a toddler cannot climb out easily. Parents put toys in, then put the child in.
