A 4-year-old needs 11–11.5 hours of sleep per night. If they wake at 7:00am, bedtime should be between 7:30pm and 8:00pm. The American Academy of Sleep Medicine recommends 10–13 hours (including naps) for ages 3–5.
A 3-year-old needs 12 hours of sleep per night. If they wake at 7:00am, bedtime should be around 7:00pm–7:30pm.
A 5-year-old needs 11 hours of sleep. For a 7:00am wake time, target bedtime is 8:00pm–8:30pm.
A consistent bedtime routine is the most effective method. Pediatric sleep experts recommend: dim lights 30 minutes before bed, warm bath, pajamas, 1–2 books or stories (a personalized story works especially well), then lights out. The key is consistency — same order, same time, every night.
