Ideal Bedtime by Age
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.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
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.
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.
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.
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 Should You Do?
When to take action
- 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
- 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
- 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

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.
Baby Only Napping 30 Minutes
Short naps of 30-45 minutes are extremely common in babies under 6 months. Your baby is waking at the end of a single sleep cycle and has not yet learned to link cycles together during the day. This is developmentally normal and typically improves on its own between 5-7 months as the brain matures.
