A nurse is discussing discipline techniques with the parent of a pre-schooler. Which of the following statements by the parent indicates an understanding of time-out as a form of discipline?

A. "I place my child in time-out for 15 minutes when they misbehave." The recommended guideline for time-out duration is one minute per year of age (e.g., a 4-year-old should have a 4-minute time-out). A 15-minute time-out is too long for a pre-schooler and may lose its effectiveness. B. "I send my child to their room for the time-out period." Time-out should occur in a designated, neutral, distraction-free space rather than a child’s bedroom, which may contain toys and other activities that reduce its effectiveness. The goal is to provide a brief period of separation to allow the child to regain control. C. "I make use of time-out after giving three warnings." While consistency in discipline is important, too many warnings can reduce the effectiveness of time-out. Immediate and clear consequences help the child associate their behavior with the discipline. D. "I use a kitchen timer to mark the end of the time-out period." Using a timer helps the child understand the structured nature of time-out and prevents the parent from extending or shortening it based on emotion. A visual or auditory cue from a timer also reinforces consistency in discipline.
