Frequently Asked Questions

Most children stop napping between ages 3-5. Signs they're ready include: difficulty falling asleep at nap time, taking very long naps that interfere with nighttime sleep, or being unable to fall asleep at bedtime. The transition should be gradual.

Yes. During puberty, there's a biological shift in the circadian rhythm that makes teens naturally sleepy later. However, they still need 8-10 hours of sleep. Help them by limiting evening screen time and keeping a consistent schedule on weekends.

Establish a consistent bedtime routine (bath, books, bed), limit screens 1-2 hours before bed, keep the bedroom cool and dark, avoid sugar and caffeine in the afternoon, and ensure they get physical activity during the day.

Bedtime resistance is common. Be consistent with routines, give advance warnings ("10 minutes until bath"), offer limited choices ("blue or red pajamas?"), and avoid engaging in prolonged negotiations. A calming routine helps signal that sleep time is approaching.
