What is the recommended total daily sleep duration for preschool-aged children (3–5 years), including naps?

• A. 8–12 hours
• B. 12–14 hours
• C. 9–11 hours
• D. 10–13 hours

Answer: (D)

Preschoolers benefit from a total daily sleep of about 10–13 hours, counting both nighttime sleep and daytime naps. This range works because some children still nap for 1–2 hours and sleep roughly 9–11 hours at night, while others may nap less or not at all but still reach around 10–13 hours total. Sleep duration within this window supports mood, behavior, attention, and growth. Too little sleep can lead to daytime irritability and poor concentration, whereas sleeping significantly more than this range is uncommon for this age and often reflects longer naps or late bedtimes. Aim for a regular routine that provides a consistent bedtime and predictable nap schedule when the child still naps, keeping total sleep within about 10–13 hours.
