What time should baby go to bed? It's one of the most searched questions by new parents — and one of the most misunderstood. Put your little one down too early and they won't go to sleep. Too late and they become overtired, wired, and harder to settle than if you had started earlier. The right bedtime isn't a fixed number: it depends on age, nap schedule, and your baby's individual sleep cues. This guide gives you an age-by-age bedtime and sleep schedule from newborn to 5 years, explains why bedtime timing matters as much as sleep duration, and shows you how to read tired signs before the window closes.

Baby bedtime by age: recommended sleep schedule

There is no single universal bedtime for every baby — baby sleep schedules vary depending on their age more than any other factor. But there are clear recommended bedtime windows, and babies and children need more sleep than most parents expect. Here is an age-by-age bedtime and sleep schedule guide. All times assume a wake time around 7:00 am — adjust proportionally for earlier or later wake times.

Newborn sleep (0–3 months): no fixed bedtime yet

Newborn sleep is not yet governed by a circadian rhythm. Newborns sleep in cycles of 50–60 minutes and wake every 2 to 4 hours around the clock — day or night. There is no bedtime to set at this stage. Your little one needs to go to sleep as soon as tired cues appear, day or night.

• Total sleep needed: 14–17 hours per 24h
• Awake window between naps: 45 minutes to 1h15
• Bedtime approach: respond to tired cues — don't force a fixed bedtime

Newborn babies benefit from consistent wind-down signals even before a true bedtime is possible: dim lights, swaddling, a pacifier, soft sounds. These build sleep associations that pay off at 3–4 months. Always place newborns on their back to reduce the risk of SIDS — never on the stomach or side. Never use a waterbed or soft surface for newborn sleep. If baby cries despite appearing tired, check for hunger or discomfort before starting the bedtime routine. Newborns tend to sleep in short stretches — usually 2 to 3 hours at a time — and wake multiple times during the night to feed. This is normal; it does not mean baby's sleep is broken.

3–6 months: an early bedtime emerges

Around 3 months, melatonin production begins and the circadian rhythm starts to develop. This is when a consistent bedtime starts to make biological sense. Your little one can now go to sleep at a predictable time in the evening and start sleeping through longer stretches — some babies start sleeping through the night, or close to it, in this window. As baby grows, the sleep they need consolidates increasingly into nighttime sleep rather than spread across many short naps.

• Recommended bedtime: 6:30–8:30 pm
• Total sleep needed: 12–15 hours (3–5 naps)
• Awake window before bed: 1h30–2h after last nap

An early bedtime at this stage — between 7:00 and 8:00 pm — tends to produce better night sleep than a later one. Baby may surprise you by sleeping longer when put down earlier. Tummy time during the day helps baby develop motor skills and also contributes to daytime tiredness that supports a reliable bedtime.

6–12 months: bedtime stabilizes around 7–8 pm

Baby moves to 2 naps per day. The ideal baby bedtime at this age is typically 7:00–8:00 pm — about 2.5 to 3 hours after the last nap ends. A consistent bedtime at this stage dramatically reduces night wakings and helps baby sleep for longer stretches. At 6 months, baby should be able to sleep 6 or more hours at a time at night. Keep baby's sleep space clear of loose bedding, toys, and bumpers to ensure safe sleep in the crib.

• Recommended bedtime: 7:00–8:00 pm
• Total sleep needed: 12–15 hours (2 naps)
• Awake window before bed: 2h30–3h after last nap

1–3 years: one nap, regular bedtime

Toddlers take one midday nap. The bedtime becomes more predictable — and routine becomes the most powerful tool for good night sleep. A toddler who skips naps or naps too late will often arrive at bedtime overtired. Sleep regressions at 18 months and 2 years can temporarily disrupt the bedtime routine — stay consistent and the sleep pattern reestablishes within days.

• Recommended bedtime: 7:00–8:30 pm
• Total sleep needed: 11–14 hours (1 nap)
• Awake window before bed: 4–5 hours after nap

3–5 years: nap fades, bedtime holds

Between 3 and 5 years, the nap gradually disappears. Without daytime sleep to fill the gap, a late bedtime accumulates sleep debt fast. Many 3-year-olds actually need an earlier bedtime when they drop the nap — sometimes as early as 6:30–7:00 pm.

• Recommended bedtime: 7:00–8:30 pm
• Total sleep needed: 10–13 hours
• Wake time: 6:30–8:00 am depending on bedtime

Why bedtime timing matters as much as sleep duration

Most parents focus on how much sleep — total hours per night. But when baby goes to bed matters just as much. Here is why.

The sleep window is the biological window during which baby is ready to go to sleep. It's driven by two forces: sleep pressure (the buildup of adenosine during daytime waking) and the circadian rhythm (which cues melatonin release in the evening). These two systems create a window of optimal sleepiness. Miss it, and the situation reverses.

When baby is overtired, the adrenal glands release cortisol — a stress hormone — to compensate for exhaustion. This cortisol creates a "second wind": baby appears re-energized just as they were tipping into sleep. A little one who was yawning at 7:00 pm and seems wired at 8:30 pm has not rested: they've missed the bedtime window, and the cortisol is now working against you. Falling asleep will take much longer, and night sleep quality suffers.

Practical insight: an earlier bedtime — even 20–30 minutes earlier than current practice — often shortens the time it takes baby to fall asleep and improves the whole night. A later bedtime does not produce equivalent sleep to an earlier one of the same duration: daytime behavior and night sleep quality both differ.

Wake time anchors the whole schedule. A consistent morning wake time sets the circadian clock and predicts when the bedtime sleep window will open each evening. Sleeping in on weekends can shift the sleep pattern for 2–3 days, making Monday night bedtime harder.

What science says about how much sleep babies need

The American Academy of Pediatrics (AAP) recommends the following total daily sleep amounts — these include naps:

How much sleep your baby needs is determined by age and development, not by how tired they seem. Every baby is different — some little ones are natural short sleepers and thrive at the lower end; others need the upper bound to function well. The amount of sleep babies and children need decreases as they grow: a newborn needs as much as 17 hours; a 4-year-old typically needs 10–12. Signs your baby may not be getting enough sleep: difficulty waking in the morning, daytime crankiness, falling asleep easily in the car or stroller, poor focus, or high emotional reactivity during the day. If your baby seems to sleep as much as the recommended range but still shows these signs, discuss it with your pediatrician — there may be a night sleep quality issue rather than a quantity issue.

Sleep regression periods — common around 4 months, 8–10 months, 12 months, 18 months, and 2 years — temporarily disrupt night sleep and can shift the bedtime window. These are normal neurological transitions, not signs of a broken sleep schedule. Maintaining a consistent bedtime routine during regressions is the best strategy.

Jet lag after travel and time zone changes disrupts the circadian rhythm in the same way, often shifting bedtime by 1–2 hours. Re-anchor with consistent light exposure and a fixed wake time to re-establish the baby sleep schedule within 3–5 days. The total sleep time doesn't change with jet lag — but the timing does, and bedtime might shift significantly until the circadian clock resets.

Signs baby is ready for bed — and signs you've missed the window

Reading tired cues is the most practical skill for finding the right baby bedtime. These cues appear at the opening of the sleep window — act on them, don't wait.

Tired cues (sleep window is open — time to start the bedtime routine)

• Repeated yawning
• Eye-rubbing, heavy eyelids, glassy stare
• Decreased interest in play and surroundings
• Slower, calmer movements
• Reaching for you, wanting to be held or nurse

Overtired cues (sleep window has closed — bedtime will be harder)

• Sudden burst of energy after an obviously tired period
• Increased fussiness — baby cries without clear cause
• Hyperactivity, difficulty settling or calming
• Intense eye-rubbing with irritability
• Baby fights bedtime despite clear exhaustion

A tired baby falls asleep quickly when you respond to cues. An overtired baby fights sleep for 30–60 minutes despite everything you try. If baby consistently fights bedtime, move the bedtime 20 minutes earlier the next night — don't wait until they're more tired.

Separation anxiety disorder symptoms, common at 9–18 months, can make bedtime harder even when timing is right. Baby may cry at bedtime not from being under-tired but from difficulty with separation. A calm, predictable bedtime routine — not a later bedtime — is the solution. Breastfeeding before bed is a natural part of many bedtime routines and helps baby go to sleep; just make sure baby is drowsy but not fully asleep at breast to avoid a strong feed-to-sleep association.

How to set a consistent bedtime routine

Consistency is the most powerful lever for a stable baby sleep schedule. A fixed bedtime, held 7 nights a week, synchronizes baby's circadian clock, reduces time to fall asleep, and improves the quality of night sleep cycles.

Build a baby bedtime routine your little one can count on

A predictable baby bedtime routine — bath, feed, story, dim lights, sleep sack — signals to baby's brain that it's time to go to sleep. Your baby's bedtime routine tells their nervous system: sleep is coming, it's safe to wind down. To help your baby fall asleep reliably and put your baby to sleep with less struggle, the bedtime routine should:

• Last 20–30 minutes (shorter for young babies, up to 30 minutes for toddlers)
• Follow the same order every night
• End in the sleep space (crib or bassinet) while baby is drowsy but awake
• Exclude screens and stimulating play

A consistent bedtime routine — even a simple one — is more effective than a perfect routine done inconsistently. Your baby's bedtime routine is the clearest signal you can give that it's time to go to sleep. Babies and young children who have a consistent bedtime routine fall asleep faster and wake less during the night than those without one.

Set a fixed wake time

Wake time — the awake time at the start of the day — is the anchor of the baby sleep schedule. A consistent morning wake time predicts when the circadian rhythm will produce the evening bedtime window. If your little one wakes at 7:00 am daily, bedtime tiredness reliably appears by 7:00–8:00 pm. Vary the wake time and you vary the bedtime. Baby go to bed later tonight because of a late start to the day? Expect the whole schedule to shift — it's the circadian system responding logically.

Shift bedtime gradually

If the current bedtime is too late, move it earlier by 15 minutes every 2–3 nights. Baby goes back to sleep more easily with gradual changes than with sudden one-hour shifts. An earlier bedtime might feel counterintuitive — but a bedtime as early as 6:30–7:00 pm is a reasonable bedtime for babies 6–18 months old who wake at 7:00 am. It is not too early; it is biologically appropriate.

Common mistakes that push bedtime later

Waiting for baby to show "obvious" tiredness

By the time baby is clearly exhausted, they're often already overtired. The bedtime window opened — and closed — 30–45 minutes ago. Act on the first tired cues, not the second wind.

A nap that ends too late

A nap ending after 4:00–5:00 pm pushes bedtime back by 1–2 hours. For babies 6–12 months, the last nap should end by 4:00 pm. For toddlers on one nap, the nap ending by 3:00 pm keeps the bedtime on track.

Screens before bed

Blue light suppresses melatonin production, delaying the biological signal for sleep. Avoid all screens in the hour before bedtime. Even brief evening screen time can delay baby's go-to-sleep signal by 30–60 minutes.

Irregular bedtimes across the week

A later bedtime on weekends shifts the circadian rhythm for 2–3 days. Variations of more than 30 minutes in bedtime or wake time disrupt the baby sleep schedule even when total sleep time seems adequate.

FAQ

What time should a 6-month-old go to bed?

Between 7:00 and 8:00 pm for a 6-month-old. The sleep window opens about 2.5 to 3 hours after the last nap. A later bedtime risks overtiredness and a cortisol rebound that makes falling asleep much harder.

How do I know my baby is overtired?

An overtired baby gets a second wind — appearing energetic after showing tired signs minutes earlier. This is a cortisol-driven rebound. A tired baby falls asleep quickly; an overtired baby fights sleep despite exhaustion.

Is it bad to put baby to bed too late?

Occasionally, no. Regularly, yes — a late bedtime builds sleep debt, disrupts the circadian rhythm, and worsens night wakings. Earlier bedtimes (before 8:30 pm for under-3s) consistently produce better night sleep quality.

Should baby go to bed at the same time every night?

Yes. A consistent bedtime routine and fixed bedtime synchronize baby's circadian clock, reduce time to fall asleep, and improve night sleep. Variations greater than 30 minutes disrupt this rhythm even if total sleep seems adequate.

What age can children start going to bed later?

Gradually from age 5–6. Before this age, bedtime between 7:00 and 8:30 pm meets biological sleep needs. The natural circadian shift toward later sleep happens during puberty.
