Sleep concerns affect nearly every family at some point. When it comes to ideal bedtime by age, here is what the guidelines recommend.

The short answer

Most babies and toddlers do best with a bedtime between 6:00 and 8:00 PM, depending on their age, nap schedule, and morning wake time. An appropriately early bedtime aligns with the natural rise in melatonin and the circadian rhythm, leading to easier settling, longer nighttime sleep stretches, and less night waking. A bedtime that is too late often leads to overtiredness, not better sleep.

Key takeaways

  • Most babies and toddlers do best with a bedtime between 6:00 and 8:00 PM, depending on their age, nap schedule, and morning wake time. An appropriately early bedtime aligns with the natural rise in melatonin and the circadian rhythm, leading to easier settling, longer nighttime sleep stretches, and less night waking. A bedtime that is too late often leads to overtiredness, not better sleep.
  • Usually normal when: Your baby or toddler falls asleep within 10-20 minutes of being put to bed at their usual bedtime
  • Call your doctor if: Your baby seems extremely overtired but cannot fall asleep despite your efforts, has an unusual cry, or appears to be in pain rather than having a schedule issue
  • Varies by age — see the age-by-age breakdown below
“To reduce the risk of sleep-related infant deaths, the AAP recommends that infants sleep on their backs, on a firm, flat surface, without any soft bedding.”

This is one of the most common questions parents ask. Searching for answers means you care.

What Parents Should Know

According to AAP, NSF guidelines, most babies and toddlers do best with a bedtime between 6:00 and 8:00 PM, depending on their age, nap schedule, and morning wake time. An appropriately early bedtime aligns with the natural rise in melatonin and the circadian rhythm, leading to easier settling, longer nighttime sleep stretches, and less night waking. A bedtime that is too late often leads to overtiredness, not better sleep. At 0-3 months, newborns do not have a set bedtime because their circadian rhythm has not yet developed. Sleep is spread throughout the day and night in irregular cycles. Around 6-8 weeks, a natural bedtime begins to emerge, typically between 7:00 and 10:00 PM. Follow your baby's cues rather than the clock at this stage - when they cluster feed and become drowsy in the evening, that is their natural bedtime forming. It is generally considered normal when your baby or toddler falls asleep within 10-20 minutes of being put to bed at their usual bedtime. However, you should contact your pediatrician promptly if your baby seems extremely overtired but cannot fall asleep despite your efforts, has an unusual cry, or appears to be in pain rather than having a schedule issue.

By Age

What to expect by age

0-3 months

Newborns do not have a set bedtime because their circadian rhythm has not yet developed. Sleep is spread throughout the day and night in irregular cycles. Around 6-8 weeks, a natural bedtime begins to emerge, typically between 7:00 and 10:00 PM. Follow your baby's cues rather than the clock at this stage - when they cluster feed and become drowsy in the evening, that is their natural bedtime forming.

3-6 months

As the circadian rhythm matures, bedtime naturally moves earlier, usually settling between 6:30 and 7:30 PM. This may feel surprisingly early, but it aligns with the natural melatonin surge. If your baby is taking a late catnap (around 5:00 PM), bedtime can be closer to 7:30-8:00 PM. If the last nap ends by 3:30-4:00 PM, an earlier bedtime around 6:30-7:00 PM prevents overtiredness.

6-12 months

Ideal bedtime for most babies this age is between 6:00 and 7:30 PM. During nap transitions (such as dropping from 3 naps to 2 around 7-8 months), you may need to temporarily move bedtime earlier by 30-60 minutes to compensate for the lost nap. A good guideline is that bedtime should be 2.5-3.5 hours after the last nap ends, depending on your baby's age within this range.

12-36 months

Most toddlers do well with a bedtime between 7:00 and 8:00 PM. During the 2-to-1 nap transition (typically 14-18 months), bedtime may need to be as early as 6:00-6:30 PM on days when the second nap is skipped. Once fully on one nap, a bedtime of 7:00-7:30 PM is typical. If your toddler consistently takes over 30 minutes to fall asleep at bedtime, the timing may need adjustment.

What to Tell Your Pediatrician

  • Describe when you first noticed ideal bedtime by age and how it has changed over time.
  • Note your baby's current age and which age-specific patterns you are seeing.
  • Mention if your baby consistently takes more than 30 minutes to fall asleep at bedtime despite seeming tired, which may indicate the timing is off.
  • Mention if your baby has frequent early morning wakings (before 5:30 AM) that do not resolve with schedule adjustments.
  • Bring a list of any questions or observations you want to discuss at the appointment.

What Should You Do?

When to take action

Probably normal when...
  • Your baby or toddler falls asleep within 10-20 minutes of being put to bed at their usual bedtime
  • Your baby sleeps 10-12 hours overnight (with age-appropriate night feeds for younger babies)
  • Your baby wakes in a generally good mood and can stay awake for age-appropriate windows
  • Bedtime shifts slightly earlier or later during nap transitions and then stabilizes
Mention at your next visit when...
  • Your baby consistently takes more than 30 minutes to fall asleep at bedtime despite seeming tired, which may indicate the timing is off
  • Your baby has frequent early morning wakings (before 5:30 AM) that do not resolve with schedule adjustments
  • Your toddler has bedtime resistance every night that causes significant family stress
Act now when...
  • Your baby seems extremely overtired but cannot fall asleep despite your efforts, has an unusual cry, or appears to be in pain rather than having a schedule issue
  • Excessive daytime sleepiness combined with very poor nighttime sleep, snoring, or pauses in breathing during sleep - this may indicate a sleep-related breathing issue

What You Can Do at Home

  • Keep track of when you notice ideal bedtime by age — noting the time of day, duration, and any triggers can help your pediatrician.
  • Remember that your baby or toddler falls asleep within 10-20 minutes of being put to bed at their usual bedtime — this is generally within the range of normal.
  • At 0-3 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
  • Maintain a consistent bedtime routine. Keep the sleep environment cool, dark, and quiet.
  • While monitoring at home, seek immediate care if your baby seems extremely overtired but cannot fall asleep despite your efforts, has an unusual cry, or appears to be in pain rather than having a schedule issue.

Related Sleep Concerns

How Long Should Baby Be Awake Between Naps?

The ideal awake time between naps (called a "wake window") increases as your baby grows. Newborns may only handle 45-90 minutes awake, while toddlers can manage 4-6 hours. Getting wake windows right is one of the most effective ways to improve nap quality, because both too-short and too-long wake times lead to poor sleep.

Is a Bath Before Bed Really Necessary?

A nightly bath is not medically necessary and some babies with sensitive skin do better with less frequent bathing. However, a warm bath can be a powerful sleep cue because the subsequent body temperature drop triggers melatonin production. If you include a bath, keep it calm and warm rather than stimulating.

How Long Should the Bedtime Routine Be?

An ideal bedtime routine for babies and toddlers is 20-30 minutes. Shorter routines may not give enough time to wind down, while routines longer than 45 minutes can become a stalling tactic. Consistency in the routine order matters more than exact length.

Is My Baby's Bedtime Too Early?

For most babies over 3 months, bedtime between 6:00-8:00 PM is appropriate. A bedtime that is too early can cause early morning wakings (before 6 AM) or long periods of wakefulness in the middle of the night. However, during nap transitions or on days when naps were short, an earlier-than-usual bedtime helps prevent overtiredness.

Is My Baby's Bedtime Too Late?

For babies over 3-4 months, consistently going to bed after 8:30-9:00 PM may result in overtiredness, which paradoxically makes it harder to fall asleep and stay asleep. Cortisol rises when babies are overtired, leading to more night wakings and early mornings. Moving bedtime earlier, even by 15-30 minutes, often improves overnight sleep quality.

Is It Dangerous for My Baby to Sleep in a Car Seat?

Babies should not be left to sleep in car seats outside of the car. Car seat-related deaths are most often caused by positional asphyxia, which occurs when a baby's head falls forward, compressing the airway. While car seats are essential and safe for travel, the AAP recommends transferring your sleeping baby to a firm, flat sleep surface as soon as you reach your destination. Never use a car seat as a substitute for a crib or bassinet.
