How Much Sleep Do Babies and Toddlers Need by Age?
Babies’ and toddlers’ sleep needs change quickly during the first three years. The table below summarizes recommended total sleep by age, followed by flexible schedule examples and practical answers to common questions about naps, bedtime and early waking.
These are starting points, not rules. Feeding needs, health, development and your pediatrician’s advice should always take priority—particularly during the newborn period.
The sleep-duration ranges below come from CDC guidance. The nap patterns are common examples, not official targets, and children may move between patterns during transitions.
| Age | Recommended total sleep | Common nap pattern |
|---|---|---|
| Newborn, 0–3 months | 14–17 hours | Sleep distributed across day and night |
| Infant, 4–6 months | 12–16 hours, including naps | Commonly 3–4 naps |
| Infant, 7–9 months | 12–16 hours, including naps | Commonly 2–3 naps |
| Infant, 10–12 months | 12–16 hours, including naps | Commonly 2 naps |
| Toddler, 12–18 months | 11–14 hours after the first birthday | Often transitioning from 2 naps to 1 |
| Toddler, 18–24 months | 11–14 hours, including naps | Commonly 1 nap |
| Age 2 | 11–14 hours, including naps | Usually 1 nap; occasional no-nap days |
| Age 3 | 10–13 hours, including naps | 0–1 nap, or quiet time |
These are 24-hour totals, not required nighttime amounts. A child does not need to land on exactly the same number every day, and the ranges do not prescribe a particular bedtime or nap schedule. The AAP notes that babies do not develop regular sleep cycles until about 4 months, so newborn sleep is often fragmented and unpredictable.

Sample sleep schedules by age
The schedules below are examples of how a day might be organized. They are not official AAP schedules, and the clock times are deliberately approximate. Use them to understand the shape of a day, not to judge whether your child is doing sleep “correctly.” Except where a full sleep period is shown, nap times indicate approximate starts, not recommended durations.
Newborn sleep schedule: 0–3 months
Recommended total sleep: about 14–17 hours in 24 hours.
Common pattern: sleep in short stretches across day and night, with frequent waking for feeding and care.
What I would focus on as a parent: feeding, safe sleep, learning the baby’s signals and keeping nights calm rather than trying to train the clock. Newborns can have day-and-night confusion, and sleep may come in one- or two-hour stretches. If your clinician has given feeding instructions because of weight, jaundice, prematurity or another issue, those instructions outrank any sleep plan.
Why the schedule may change: feeding frequency, growth spurts, recovery from birth, prematurity, illness and simple day-to-day variability.
4–6-month sleep schedule
Recommended total sleep: 12–16 hours in 24 hours, including naps.
Common pattern: a more recognizable night period plus multiple naps, although nap length may still be inconsistent.
| Approximate timing | Example event |
|---|---|
| 7:00 AM | Wake and feed |
| Around 9:00 AM | Nap 1 begins |
| Around 12:00 PM | Nap 2 begins |
| Around 3:00 PM | Nap 3 begins |
| 6:30–7:30 PM | Bedtime range |
What I noticed as a parent: this was the stage when looking at both the clock and the child became more useful than either one alone. A schedule could begin to appear, but the final nap often changed bedtime. Some days needed more flexibility than others.
Why the schedule may change: developmental progress, feeding changes, short naps, illness, travel and a rapidly changing ability to stay awake.
7–9-month sleep schedule
Recommended total sleep: 12–16 hours in 24 hours, including naps.
Common pattern: increasingly predictable mornings, with many babies moving from three naps toward two.
| Approximate timing | Example event |
|---|---|
| 6:30–7:00 AM | Wake |
| 9:00–9:30 AM | Nap 1 begins within this range |
| 1:00–2:00 PM | Nap 2 begins within this range |
| 4:00–5:00 PM | Optional short third nap begins within this range |
| 7:00–8:00 PM | Bedtime range |
What I noticed as a parent: transitions were rarely tidy. A baby could look ready for two naps after a great day, then need a third nap after an early morning or two short naps. The last nap often mattered because a late nap could push bedtime later, while skipping it could make the evening feel very long.
Why the schedule may change: early waking, short naps, teething, illness, new movement skills and the gradual three-to-two-nap transition.
10–12-month sleep schedule
Recommended total sleep: 12–16 hours in 24 hours, including naps.
Common pattern: two naps are common, but a temporary nap refusal does not automatically mean a child is ready for one nap.
| Approximate timing | Example event |
|---|---|
| 6:30–7:00 AM | Wake |
| 9:30–10:00 AM | Nap 1 begins within this range |
| 2:00–2:30 PM | Nap 2 begins within this range |
| 7:00–8:00 PM | Bedtime range |
What I noticed as a parent: protecting the overall amount of rest was more helpful than trying to force exact clock times. A single refused nap often reflected an unusual day rather than a permanent transition.
Why the schedule may change: separation anxiety, new skills, teething, illness, travel, longer naps or an unusually early morning.
12–18-month sleep schedule
Recommended total sleep: 11–14 hours in 24 hours, including naps once the child is 1 year old. The published age bands meet at the first birthday, so this should not be treated as an overnight change in a child’s target.
Common pattern: transition from two naps to one. Mixed one-nap and two-nap days can occur during the transition.
| Example pattern | Illustrative timing |
|---|---|
| Two-nap day | Wake 6:30–7:00 AM; naps begin around 9:30 AM and 2:00 PM; bedtime 6:30–7:30 PM |
| One-nap day | Wake 6:30–7:00 AM; nap begins between 12:00 and 1:00 PM; bedtime 6:30–7:30 PM |
What I noticed as a parent: the transition felt more like a period than a decision made on one date. When daytime sleep was unusually short, an earlier bedtime often made more sense than trying to stretch the child to a normal bedtime.
Why the schedule may change: nap transition, child care routines, walking and other developmental changes, illness and inconsistent nap length.
18–24-month sleep schedule
Recommended total sleep: 11–14 hours in 24 hours, including naps.
Common pattern: one midday nap for many toddlers, with a recognizable evening wind-down routine.
| Approximate timing | Example event |
|---|---|
| 6:30–7:00 AM | Wake |
| 12:30–1:00 PM | Nap begins within this range |
| 7:00–8:00 PM | Bedtime range |
What I noticed as a parent: the routine around sleep became just as important as the schedule itself. A familiar sequence such as dinner, bath, brush, book and bed could help signal that the day was ending.
Why the schedule may change: illness, language and motor development, separation, travel, a long nap, a late nap or a missed nap.
Two-year-old sleep schedule
Recommended total sleep: 11–14 hours in 24 hours, including naps.
Common pattern: one nap remains common, but occasional no-nap days may begin for some children.
| Approximate timing | Example event |
|---|---|
| 6:30–7:00 AM | Wake |
| 12:30–1:00 PM | Nap begins within this range, if needed |
| 7:00–8:30 PM | Bedtime range, depending on the nap and the child |
What I noticed as a parent: nap days and no-nap days did not always support the same bedtime. A long or late nap could make bedtime harder, while no nap could make an earlier and calmer bedtime necessary.
Why the schedule may change: nap length, preschool or child care, activity level, illness, developmental changes and growing independence.
Three-year-old sleep schedule
Recommended total sleep: 10–13 hours in 24 hours, including naps.
Common pattern: some children still nap; others move toward quiet time instead.
| Approximate timing | Example event |
|---|---|
| 6:30–7:00 AM | Wake |
| 12:30–2:00 PM | Nap or quiet time begins within this range |
| 7:00–8:30 PM | Bedtime range |
What I noticed as a parent: this stage often required looking at the whole 24 hours. If a nap was clearly delaying bedtime, shortening it or replacing it with quiet time could be worth discussing and testing gradually.
Why the schedule may change: dropping the nap, preschool schedules, bedtime resistance, new fears, illness and changes in daytime activity.
How to choose bedtime when wake-up time and naps keep changing
Should bedtime be based on wake-up time or the last nap?
The whole day matters, but the end of the final nap is often the most immediately useful clue because it tells you how much sleep pressure may have built by evening. That does not make bedtime a rigid formula. Consider the child’s total sleep, mood, how restorative the naps seemed, and whether bedtime has recently become difficult.
What counts as morning if a baby wakes at 5 AM and falls asleep again?
If the child wakes briefly and then returns to meaningful sleep, I would usually think of that as a night waking rather than the official start of the day. If the lights go on and feeding and play begin, and the child stays awake, it functions more like morning. The repeated pattern matters more than one unusual 5 AM wake-up.
Should the first nap follow actual or desired wake time?
On an unusually early morning, it is usually more practical to respond to the child you actually have in front of you rather than pretending the desired wake time happened. At the same time, repeatedly putting the first nap extremely early can anchor an early day for some families. A gradual shift is often easier than a sudden one.
Should parents wake a baby to preserve the morning schedule?
Age and health matter. Do not adjust a newborn’s sleep or feeding schedule simply to preserve a family clock without considering feeding needs, growth and medical advice. For an older healthy baby, some families choose a reasonably consistent morning wake time because it helps organize naps and bedtime, but it is not a requirement for every child.
What if the final nap ends much earlier than usual?
You have several reasonable options: use an earlier bedtime, consider a brief bridging nap if the child’s age and pattern still support one, shorten and calm the final awake period, or simply accept one awkward day. One strange afternoon does not require redesigning the entire schedule.
Must bedtime remain identical every night?
No. Consistency is useful, but consistency is not the same as forcing sleep at the exact same minute. The AAP encourages predictable routines and regular sleep times. In real homes, nap quality, illness and family events can make some variation sensible.
How much can bedtime vary?
There is no universal medically approved number of minutes that every baby or toddler may vary. In my own parenting, I found it more useful to keep a recognizable bedtime range and routine, then adjust when naps or the child’s behavior clearly called for it. The important question was whether the variation helped the child obtain enough total sleep and settle reasonably well.
What parents report about changing bedtime
Parent experiences are mixed. Some families calculate bedtime mostly from the last nap, while others protect a fairly consistent clock-based bedtime. On unusual nap days, parents often debate an early bedtime versus a short bridge nap. Some report that an earlier bedtime gives a later morning; others see the opposite. The conflict itself is useful: it is a reason to track your own child’s response instead of treating either strategy as universally correct.
Short naps, wake windows and “rescuing” naps
Wake windows can be a convenient planning language, but they are not biological reset buttons and there is no single official medical chart that tells every child exactly how long to stay awake at each age. I use them as context, not as a deadline.
Should the next wake period be shorter after a short nap?
Possibly. A 20- or 30-minute nap may not leave a child as refreshed as a long nap. Instead of automatically subtracting a fixed number of minutes, watch mood, feeding, activity, sleepy cues and how the next settling attempt goes.
Does a 30-minute nap completely reset the wake window?
No. Sleep does not work like pressing a reset button on a stopwatch. Nap length is one clue among many. The same 30-minute nap can affect two children differently, and even the same child may respond differently on different days.
Should you rescue a short nap?
You can briefly try to resettle if that is realistic for your family, or accept the nap and adjust the rest of the day. Neither approach is automatically superior. Persistent very short sleep, especially with feeding, breathing, growth or daytime concerns, belongs in a conversation with your pediatrician.
What matters more: total awake time or individual wake windows?
The complete 24-hour pattern matters more than any single interval. Look at total sleep, night waking, naps, mood, feeding, ease of settling and daytime function.
When should a nap be capped?
Some parents consider capping when a late nap repeatedly delays bedtime, one long nap consistently displaces another, or nighttime sleep appears regularly affected. That does not mean every long nap should be shortened. First look for a repeated pattern rather than reacting to one good sleep.
Should the last nap be shortened to protect bedtime?
Sometimes, particularly during a nap transition when the final nap keeps pushing bedtime later. But shortening it can also create an overtired evening for some children. Test changes gradually and judge the result over several days.
What parents report about short naps
Some parents try to extend a short nap through rocking, contact or resettling. Others accept it and move on. A short nap may create the need for an extra nap later, while two longer naps may remove that need. Across parent discussions, there is no consistent rule that a 30-minute nap resets a wake window in exactly the same way every time. Many parents describe feeling less anxious once wake-window charts become guides instead of countdown timers.
How to recognize a nap transition
Is the baby ready to drop a nap, or simply having a difficult week?
Look for a repeated pattern rather than one refusal. Possible signs include regularly refusing the same nap, taking much longer to fall asleep, bedtime becoming consistently difficult, coping comfortably with longer awake periods, and maintaining reasonable mood and total sleep. Illness, teething, travel and developmental bursts can temporarily imitate a transition.
What if the baby needs three naps one day and two the next?
That can be completely normal during a transition. This is one of the clearest lessons I took from parenting: transitions do not have to be neat. A short-nap day may still need the third nap. A later morning or two long naps may not. Alternating days can be more realistic than declaring that the old schedule ended on Tuesday.
Can daytime sleep be too long despite 11 hours at night?
Possibly, if the daytime sleep is regularly making bedtime very late or creating a pattern that no longer works for the child or family. But judge total sleep over 24 hours first. A schedule can fall within the recommended range and still need practical adjustment.
What parents report during nap transitions
A common parent pattern is alternating between two- and three-nap days for several weeks. Short naps, early waking, illness and teething may temporarily bring the extra nap back. Many parents notice the last nap becoming difficult or pushing bedtime later before the transition settles. These anecdotes illustrate why a nap transition is better viewed as a period, not a single date on which the old schedule must disappear.
Toddler naps and bedtime decisions
Should a two-year-old’s bedtime depend on nap length?
It can. A toddler who sleeps a long time late in the afternoon may simply not be ready for the same bedtime as on a no-nap day. A toddler who skips the nap may need a much earlier wind-down. Look for the pattern across several days.
How late is too late for a toddler nap?
There is no universal clock cutoff. A nap is “too late” in a practical sense when it repeatedly makes the child unable to settle at the family’s reasonable bedtime or pushes the whole schedule later than desired.
Should you wake a toddler after a poor night’s sleep?
There is a trade-off. Recovery sleep may be useful after a rough night, but a very long or late nap may delay the next night. Consider how exhausted the child is, whether they are sick, and whether the pattern is occasional or chronic.
Should you shorten a toddler’s nap or drop it completely?
If bedtime is consistently difficult but the child still seems to benefit from daytime sleep, shortening or moving the nap earlier can be a gentler experiment than eliminating it immediately.
Can a two-hour nap contribute to nighttime waking?
It can contribute in some children by reducing sleep pressure at night, but it does not prove causation. Night waking can also relate to illness, environment, separation, habits, discomfort, development or other factors.
What should bedtime be after a refused nap?
Usually think earlier and calmer rather than aiming for an exact universal time. Watch the child’s behavior. A no-nap toddler who is falling apart by dinner may need a much earlier bedtime than usual.
Should nap-day and no-nap-day bedtimes be identical?
They do not have to be. The child’s underlying sleep need may be similar, but the amount of daytime sleep is different. Many families naturally use an earlier bedtime after no nap and a later one after a substantial nap.
Does the toddler need a later bedtime or a shorter nap?
Compare how long it takes to fall asleep, mood before bed, morning waking, overnight waking and total 24-hour sleep. If the child is happy and simply not sleepy at the old bedtime after a long nap, the schedule may need adjustment. If they are exhausted but dysregulated, the answer may be different.
Should parents protect bedtime or morning wake time?
A fairly consistent morning can help anchor the day, while bedtime may need more flexibility because naps vary. The best balance is the one that protects adequate total sleep and works repeatedly, not just once.
What parents report about toddler nap changes
Parents of two-year-olds often describe a difficult middle stage: the child still seems to need a nap, but the nap can push bedtime very late. Removing it can lead to irritability or accidental late-afternoon sleep. Some families shorten the nap; others temporarily accept a later bedtime. The transition away from naps is often gradual and untidy, and a long nap does not automatically explain every night waking.
Why apparently sensible schedules sometimes behave unpredictably
False starts and clock-based night waking
A “false start” usually means a child falls asleep at bedtime and wakes again soon afterward. Parents often blame the schedule, and schedule can matter, but it is not the only possibility. A child may also be disturbed by noise, light, temperature, hunger, discomfort, illness, a change in routine or normal developmental sleep changes. Waking at roughly the same time each night can reflect a repeated environmental cue or sleep pattern, but it is not enough information to diagnose a cause.
Why earlier or later bedtime does not always produce the expected morning
Sleep is not simple arithmetic. Putting a child down one hour later does not guarantee one extra hour in the morning. A later bedtime can sometimes lead to the same wake time and therefore less total sleep. An earlier bedtime can help a tired child sleep longer, but another child may still wake at the same early hour. Weekends can be especially confusing because light exposure, activity, naps, travel and family routines change at the same time. Test one change at a time rather than using a single morning as proof.
Overtired, undertired, or simply not ready to sleep?
These labels can be useful descriptions, but they are not medical diagnoses. Their supposed signs overlap. Energetic play, crying, long settling, rapid sleep onset and short wake-ups are all interpreted differently by different parents. A single behavior cannot reliably prove that a child was overtired or undertired. Look at the broader pattern over several days: how long the child sleeps, how they wake, daytime mood, nap quality and whether the same bedtime repeatedly succeeds or fails.
What parents report about confusing sleep signals
Parent discussions are openly contradictory here. Some associate prolonged playful settling with not being tired enough. Others describe the same behavior when a child seems exhausted. False starts are blamed on both longer and shorter awake periods. That contradiction is exactly why I would not change a schedule based on one sign alone.
Why imperfect schedules occasionally work better
Sometimes a child sleeps beautifully after a day that looked “wrong” on paper. That does not mean the messy schedule caused the good night. Travel, activity, feeding, development, illness recovery and chance may all play a role. Likewise, one poor night after a schedule change does not necessarily mean the change was wrong. Patterns are more informative than isolated wins and losses.
What parents report about imperfect schedules
Some parents report better nights after dropping a nap the child repeatedly resisted. Others try the same thing, see worse sleep and temporarily return to the old schedule. Parents also sometimes report surprisingly good sleep during travel or an unstructured day. Treat those stories as observations, not instructions.
The parent sleep-log method
When sleep became confusing, the most useful tool was often not another schedule. It was a simple record. The AAP also notes that pediatricians may ask families to keep a sleep log when evaluating sleep concerns.
| Date | Morning wake | Nap start/end | Bedtime | Night waking | Mood/notes |
|---|---|---|---|---|---|
My method is simple: record before changing anything, look for a repeated pattern, change only one element at a time, observe rather than chase perfection, and note illness, travel or unusual activity. Seven days will not explain everything, but it often reveals whether a problem is truly repeated or just memorable.

Safe sleep rules that schedules must never override
For every sleep during a baby’s first year, schedule convenience must come second to a safe sleep environment. Current AAP and NIH guidance includes the following:
- Place the baby on their back for every nap and nighttime sleep.
- Use a firm, flat, level sleep surface that meets applicable safety standards, with only a fitted sheet.
- Keep pillows, loose blankets, toys, bumpers and other soft objects out of the infant sleep area.
- Use a separate infant sleep space and do not bed share. The AAP recommends room sharing without bed sharing for at least the first 6 months.
- If a baby falls asleep in a sitting device such as a car seat or swing outside travel, move them to a firm, flat sleep surface as soon as practical.
- Avoid falling asleep with a baby on a couch, armchair or other soft surface.
- Do not use an inclined sleeper, sleep positioner, weighted blanket, weighted sleeper, weighted swaddle or other unsafe product merely because it seems to preserve a schedule.
If your baby rolls independently in both directions, continue placing them on their back to start sleep. The AAP explains that you do not need to keep turning a baby back over once they can comfortably roll both ways, but the sleep area should remain clear of soft objects.

When sleep questions belong with a pediatrician
A schedule article should never turn symptoms into a nap problem. Contact your child’s pediatrician when sleep is accompanied by concerning symptoms or when persistent sleep problems are affecting daytime function. Reasons to seek medical guidance include:
- Regular snoring, loud or heavy breathing during sleep
- Gasping or observed pauses in breathing
- Unusual difficulty waking or excessive daytime sleepiness
- Feeding or growth concerns
- Persistent sleep problems that clearly affect the child’s daytime behavior or function
- A sudden major sleep change accompanied by signs of illness
The AAP specifically lists snoring, sleep apnea and loud or heavy breathing among sleep problems parents should recognize and discuss with a pediatrician. For a newborn or medically complex child, ask before making schedule changes that could affect feeding or care.

Final takeaway
The biggest lesson I have learned as a parent of two is that a useful sleep schedule is a framework for noticing patterns. It should make family life easier, not make every short nap, late bedtime or early morning feel like a failure.
Start with age-appropriate total sleep. Keep a predictable routine. Use naps and wake times as clues rather than rigid rules. Give transitions time to reveal themselves. Track repeated problems before changing several things at once. And whenever safety, feeding, breathing, growth or illness is part of the picture, put the schedule aside and talk with your pediatrician.
Children change. Good sleep planning changes with them.
