For children aged 6-17 years the question addresses nighttime sleep, based on the guidelines. Sufficient sleep is defined as 12 or more hours for ages 4 months -1 year, 11 or more hours for ages 1-2 years, 10 or more hours for ages 3-5 years, 9 or more hours for ages 6-12 years, and 8 or more hours for ages 13-14 years.
