When the child has been naughty, he or she is sent to sit still on an appointed step of a staircase for a period of time (such as one minute per year of age, e.g. 4 minutes for a 4-year-old child). If the child does not willingly accept this punishment, fails to sit still, or gets up before the time-out is over, a harsher consequence may be needed.
If there is no step available, e.g. in a one-storey house or flat, a "Naughty Rug", "Naughty Corner" or "Naughty Stool" are alternatives.
