- Total daily sleep: 12–16 hours (AAP guidance)
- Overnight sleep: ~10–12 hours, often with 1–2 wakings
- Naps: 2–3 per day, totalling ~3–4 hours
- Wake windows: ~2 to 2.5 hours between sleep periods
- The 3-to-2 nap transition typically begins between 6 and 9 months
- A sleep regression around 6 months is common and temporary
- Solid foods, teething, and developmental leaps all affect sleep at this age
How Much Sleep Does a 6 Month Old Actually Need?
The American Academy of Pediatrics (AAP) recommends that babies aged 4–12 months get 12–16 hours of total sleep in every 24-hour period, including naps. The NHS notes that sleep needs vary considerably between babies and that these figures are averages, not requirements that every baby must meet precisely.
In practice, most 6 month olds land somewhere in this range. Here is how those hours typically break down:
| Sleep Period | Typical Range | Notes |
|---|---|---|
| Total daily sleep | 12–16 hours | AAP recommended range for 4–12 months |
| Overnight sleep | 10–12 hours | Often includes 1–2 wakings, particularly for breastfed babies |
| Total nap time | 3–4 hours | Spread across 2–3 naps |
| Individual nap length | 30 min – 2 hours | Varies; many babies have 1 longer and 1–2 shorter naps |
| Wake windows | 2–2.5 hours | Slightly longer wake window before bedtime is common |
One number to hold on to: the trend matters more than any single night or day. A baby who sleeps 11.5 hours on a Tuesday because of an unsettled afternoon is not sleep-deprived. A baby who is consistently sleeping fewer than 10 total hours over multiple weeks, shows persistent tired signs during awake periods, or is struggling to settle for naps and bedtime warrants a conversation with your health visitor.
Naps at 6 Months — How Many, How Long, and When
At six months, most babies are taking either two or three naps a day. Some are solidly in a three-nap pattern; others are already showing signs that the third nap needs to go. Both are developmentally normal at this age.
The 3-Nap Day
A three-nap day at six months typically looks like two longer naps (45 minutes to 1.5 hours each) in the morning and early afternoon, and one shorter "bridge" nap or catnap (20–45 minutes) in the late afternoon. The third nap's job is to carry the baby to bedtime without becoming overtired — it is not supposed to be a long, restorative nap, and many babies only take it if you catch the exact right moment.
The 2-Nap Day
A two-nap day at six months looks quite different: two longer naps (1–2 hours each), spaced further apart, with a longer final wake window before bedtime. Babies on two naps are often more settled because the schedule is more predictable and the sleep pressure is better distributed — but the transition period from three to two naps can be rocky for a few weeks while the schedule adjusts.
Signs It's Time to Drop the Third Nap
- They consistently refuse or fight the third nap for a week or more
- The third nap is pushing bedtime so late that mornings are becoming very early
- They are taking noticeably longer to fall asleep at nap one or nap two
- They wake earlier in the morning than they used to
- The schedule feels perpetually off — settling resistance at each nap, bedtime battles
Most babies make the 3-to-2 nap transition somewhere between 6 and 9 months, with 7–8 months being the most common window. There is no need to force it earlier — if your baby is still settling well for three naps and sleeping reasonably well overnight, keep three naps until the signs above appear consistently.
Wake Windows at 6 Months — The Guide to Timing Naps Right
A wake window is the amount of time a baby can comfortably stay awake between sleep periods before becoming overtired. At 6 months, the typical wake window is 2 to 2.5 hours.
Getting wake windows right is the single biggest lever you have on nap and bedtime settling. A baby put down before their window has closed won't be tired enough to settle. A baby kept awake past their window becomes overtired — cortisol spikes, the body fights sleep, and settling becomes much harder. The sweet spot is the 20–30 minutes before the window closes.
⏱️ Wake Windows — 4 to 9 Months
Wake windows gradually lengthen as babies develop. Watch for tired signs alongside the clock — individual variation is normal.
What a 6 Month Old's Sleep Day Actually Looks Like
These sample schedules are starting points, not rigid targets. Every baby is different — yours may wake earlier, nap longer, or need a slightly different rhythm. Use these as a framework and adjust based on your baby's actual tired signs and wake times.
🌙 Sample 3-Nap Schedule — 6 Months (7am Wake)
🌙 Sample 2-Nap Schedule — 6 Months (7am Wake)
The two-nap schedule has longer wake windows and requires more from your baby between sleep periods — which is why it works better once the 3-to-2 transition is genuinely ready, rather than being forced early. For more detail on full daily schedules at this age, see our 6 month sleep schedule guide.
Why 6 Months Is Such a Big Sleep Moment
If your baby slept reasonably well at three or four months and is now suddenly harder to settle or waking more frequently — you are not imagining it. Six months involves a convergence of developmental changes that almost always affect sleep.
Around six months, babies are typically mastering rolling (in both directions), learning to push up on their arms, and beginning to sit with support. These are big physical achievements — and the brain practices them during sleep. Many parents notice their baby rolling to their front during the night for the first time and not knowing how to get back. This is developmentally normal and drives significant nighttime restlessness while the skill is being consolidated. Once rolling both ways is established, overnight rolling typically becomes a non-event.
At six months, babies are genuinely interested in the world around them — and increasingly reluctant to miss any of it. The fear of missing out (FOMO) is not a teenage phenomenon; it starts much earlier. Babies who were previously easy to settle may begin protesting bedtime or resisting naps because the interesting world is out there and sleep feels less compelling. Blackout blinds, a consistent wind-down routine, and removing stimulating toys from the sleep environment all help create the conditions for sleep despite a brain that has become very interested in staying awake.
Most families begin introducing solid foods around six months, in line with NHS and WHO guidance. The introduction of solids changes digestive patterns — some babies experience mild bloating or discomfort as their gut adapts to new foods, which can temporarily disturb sleep. Despite a common belief, solid foods at this age do not reliably improve overnight sleep — the evidence does not support the idea that a fuller baby sleeps longer, particularly when solid food amounts in the first weeks of introduction are very small.
The 6-Month Sleep Regression — What It Is and When It Ends
Many parents describe a period around six months where sleep that was improving suddenly gets significantly worse — more night wakings, shorter naps, harder settling, or all three at once. This is frequently called the 6-month sleep regression, and it is one of the most commonly reported sleep disruptions of the first year.
It is not, strictly speaking, a single regression in the way the 4-month regression is — the 4-month regression is driven by a specific architectural change in sleep cycles that is permanent. The disruption at six months is more of a convergence: developmental leaps, motor skill acquisition, teething onset, and environmental awareness all arriving within a similar window and producing a period of disrupted sleep that can last 2–6 weeks.
What Helps During a Sleep Regression
Keep the Routine Consistent
The wind-down routine — bath, feed, book, song, dark room, white noise — should stay the same every night regardless of how the night before went. Consistency in the cues that signal sleep is the most effective way to maintain sleep associations during a disruptive period. Introducing new approaches when things are difficult tends to create new habits rather than solve temporary problems.
Protect Wake Windows
When naps get disrupted, it can be tempting to let a baby sleep whenever they can to compensate. This often backfires — irregular nap timing disrupts overnight sleep further. Stick as closely as you can to age-appropriate wake windows (2–2.5 hours) even when settling is harder than usual. An extra 10–15 minutes of pre-nap wind-down during this period often helps.
Adjust Bedtime if Needed
During a period of disrupted daytime sleep, a slightly earlier bedtime (30–45 minutes earlier than usual) can help prevent cumulative overtiredness. Counter-intuitively, an overtired baby is harder to settle and often sleeps less well than a baby who goes to bed slightly tired but not exhausted. An earlier bedtime during a regression does not usually produce an earlier wake time.
Share the Night Wakings
If your partner is able to respond to some night wakings, a week of shared overnight care during a regression is much more sustainable than one parent carrying every waking. Agreeing in advance who responds to which wakings — alternating, or by time (one parent takes before 2am, the other after) — removes the cognitive load of deciding in the moment at 3am.
Track to Spot the Patterns
Logging sleep during a regression with an app like Lunara helps you see whether things are gradually improving over days, which is difficult to assess from inside a disrupted week. A week where nights 1, 3, and 5 are better than nights 2 and 4 looks like chaos in real time but looks like progress in a log. Patterns are much more visible as data than as lived experience.
Know It Will Pass
This one is not practical advice — it is just true. The 6-month sleep disruption is temporary. Most families find it lasts 2–6 weeks before sleep returns to baseline. It feels permanent from inside it. The data — and the consistent experience of parents who have been through it — says it isn't.
Why Your 6 Month Old Isn't Sleeping Well — Common Causes
Most disrupted sleep at six months has an identifiable cause. These are the most common, in order of how frequently they come up.
🚫 Overtiredness — Missing the Sleep Window
What it looks like: Your baby fights going to sleep, then passes out hard but wakes after a short cycle — 30–45 minutes — and struggles to resettle. Or bedtime becomes a battle that lasts an hour.
Why it happens:- Wake windows stretched longer than the 2–2.5 hour guideline
- Third nap dropped before the baby was ready, building too much sleep pressure before bedtime
- Late nap ended too close to bedtime (less than 1.5 hours gap)
- Pull the nap earlier — aim to start it 15–20 minutes before the end of the wake window, not at the end
- Try an earlier bedtime for a week (6:15–6:30pm instead of 7:30pm)
- Temporarily reinstate the third nap if it was recently dropped and nights got worse
🚫 Under-Tiredness — Too Much Daytime Sleep Too Late
What it looks like: Your baby isn't tired at bedtime, takes a long time to fall asleep, and then wakes very early in the morning or wakes frequently overnight without seeming hungry.
Why it happens:- Naps are too long, too late, or there are too many of them for this baby's needs
- Total daytime sleep is eating into overnight sleep pressure
- Late final nap pushes bedtime too late, which compresses overnight sleep
- Cap the third nap at 30–40 minutes and end it by 4:30–5:00pm
- If on 2 naps, ensure Nap 2 ends no later than 3:00–3:30pm for a 7pm bedtime
- Gently wake from long naps to protect overnight sleep pressure
🚫 Sleep Association Dependency
What it looks like: Your baby falls asleep easily with a feed, a rock, or a dummy — but wakes every 1–2 hours overnight and needs the same thing to go back to sleep.
Why it happens:- All babies cycle through light sleep every 45–60 minutes overnight
- A baby who needs a specific condition to fall asleep will also need that condition each time they surface through a light sleep cycle
- This is developmentally normal — but can become exhausting for families
- Put your baby down drowsy but awake when possible — this is the foundation of self-settling
- If the association is a feed, try separating the feed from the sleep — feed 20–30 minutes before the sleep routine rather than as the final step
- If overnight wakings are significantly affecting your family, speak with your health visitor about approaches that suit your parenting style — there are many options between "do nothing" and "full sleep training"
🚫 Environmental Disruption
What it looks like: Your baby wakes at the same time each night, around the same noise or light cue — or their nap timing is inconsistent because nap location keeps changing.
Why it happens:- At 6 months, babies are much more aware of their environment and more easily disturbed by light, noise, and temperature changes
- Inconsistent nap location (sometimes the pram, sometimes the cot, sometimes a carrier) can make it harder to build strong sleep associations
- Blackout blinds in the sleep room — genuine darkness makes a significant difference for many babies at this age
- White noise at a consistent level throughout the sleep period (not just for settling)
- Move towards at least one daily nap in the cot, in the room where your baby sleeps at night

Overnight Sleep — Night Feeds, Wakings & What's Normal
One of the most searched questions about 6-month sleep is some version of "should my baby be sleeping through the night by now?" The honest answer is: some babies are, and many aren't — and both are normal.
"Sleeping through the night" in clinical terms typically means a continuous stretch of 5–6 hours. By this definition, many 6 month olds are sleeping through. The 10–12 hour uninterrupted night that parents often hope for is achieved by some 6 month olds — but it is not a universal milestone that every baby hits at 6 months, and the pressure to achieve it can create anxiety that is not warranted.
Night Feeds at 6 Months
Many 6 month olds still need one or two overnight feeds — particularly breastfed babies, whose more digestible milk means genuine hunger recurs during a 12-hour overnight period. Formula-fed babies may or may not need overnight feeds by this age, depending on daytime volumes and individual needs.
Whether overnight feeds are still nutritionally necessary at 6 months is a question worth raising with your health visitor, who can assess based on your baby's specific weight, growth trajectory, and daytime feeding patterns. The answer differs baby by baby.
Rolling Overnight — What to Do
A common 6-month sleep disruption: your baby has just learned to roll and is now rolling to their front during sleep — then crying because they can't get back. The AAP and NHS guidance for this stage is clear: if your baby can roll both ways (front to back and back to front), you do not need to reposition them when they roll during sleep. Their developing motor skills mean they can manage their own position. If they roll and can't yet roll back, gently reposition them onto their back — but expect this to be a frequent overnight task for a few weeks while rolling back is consolidated.
When to Speak With Your Health Visitor or Paediatrician
Most disrupted sleep at 6 months is normal, temporary, and attributable to the developmental factors described above. But there are situations where professional input is valuable.
🩺 Contact Your Health Visitor or GP If:
These are worth a conversation — not a crisis, but not something to wait out alone either:
Sleep patterns:- Your baby is consistently sleeping fewer than 10 total hours in every 24-hour period, and seems tired, difficult to settle, and cranky during awake time
- Night wakings are so frequent (every 60–90 minutes or more) that your own health is being significantly affected
- Disrupted sleep has lasted more than 4–6 weeks with no sign of improvement
- Loud snoring, gasping, or pausing in breathing during sleep
- Your baby is extremely difficult to rouse from sleep or seems limp or very pale on waking
- Any breathing irregularity during sleep — this always warrants prompt medical assessment
- Sleep disruption is accompanied by a significant change in feeding — a baby who was feeding well and is suddenly refusing feeds, or whose weight gain has slowed unexpectedly
- If you have any instinctive concern that something isn't right — trust that instinct and make the call. That is what your health visitor is there for.
How to Track Your 6 Month Old's Sleep — And Why It Helps
One of the most disorienting things about a disrupted sleep period is the impossibility of assessing whether things are actually improving. From inside a bad week, every night feels like the worst night. But logged data tells a different story — you can see whether Tuesday was better than Monday, whether this week has more total sleep than last week, and whether the pattern is trending in the right direction even if individual nights are still hard.
A sleep tracking app like Lunara logs each nap and overnight sleep with one tap, calculates daily totals and weekly averages automatically, and shows the pattern across days and weeks in a way that is impossible to track mentally. During a regression or disrupted period, this data serves two purposes: it reassures you when things are improving faster than they feel like they are, and it gives your health visitor accurate information if you need to seek support.
The sleep log also captures what your health visitor most needs at the 6-month developmental check: how long are overnight stretches? How many naps? Total daily sleep hours over the past week? These questions are easy to answer with an app and very hard to answer accurately from memory.
Frequently Asked Questions — 6 Month Old Sleep
Most 6 month olds need 12–16 hours of total sleep across every 24-hour period, according to AAP guidance. This typically breaks down into approximately 10–12 hours overnight and 3–4 hours across 2 to 3 daytime naps. These are ranges — a baby who consistently sleeps 12 hours, gains weight well, and is alert and content when awake is getting adequate sleep even if the total is below the mid-range average. Total sleep needs vary between babies, and every baby develops at their own pace.
Most 6 month olds take 2 to 3 naps per day. Some are still solidly on 3 naps; others are beginning to consolidate to 2. A 3-nap day includes two longer naps (45 min–1.5 hours each) and one short catnap (20–45 min) in the late afternoon. A 2-nap day includes two longer naps (1–2 hours each) with no third nap. The 3-to-2 nap transition typically happens between 6 and 9 months — watch for consistent third-nap refusal, settling resistance, or earlier morning waking as signs that the transition is ready.
Most 6 month olds sleep approximately 10–12 hours overnight, often with 1–2 wakings — particularly breastfed babies, who may genuinely need a feed during the overnight period. Some 6 month olds sleep a consolidated stretch of 6–8 hours or more without waking; others still wake more frequently. Both patterns are within the normal range. If your baby is waking 3 or more times overnight and struggling to resettle without significant help, speak with your health visitor about approaches that might work for your family.
At 6 months, most babies can comfortably stay awake for approximately 2 to 2.5 hours between sleep periods. The last wake window of the day — before bedtime — is often the longest, sometimes stretching to 2.5–3 hours. Watch your baby for tired signs alongside the clock: tired signs include eye rubbing, yawning, turning away from stimulation, increased fussiness, or losing interest in play. Aim to start the wind-down routine 20–30 minutes before the end of the wake window, not at the end.
Yes — many parents experience a significant sleep disruption around 6 months. Unlike the 4-month regression (which is driven by a permanent change in sleep architecture), the 6-month disruption is more of a convergence of factors: rolling and motor skill acquisition, increased environmental awareness, teething onset, and the introduction of solid foods all arriving within the same window. It typically lasts 2–6 weeks. Maintaining a consistent routine and appropriate wake windows is the most effective approach. It is temporary — things return to baseline once the developmental leap settles.
Not necessarily. Many 6 month olds still wake once or twice overnight and need a feed or some reassurance to resettle — this is developmentally normal. "Sleeping through" in clinical terms means a continuous stretch of 5–6 hours, which many 6 month olds achieve. The full 10–12 hour night without waking is common for some babies by 6 months but not yet for others. The pressure to achieve this milestone can create anxiety that isn't warranted. If overnight waking is significantly affecting your family's sleep and wellbeing, speak with your health visitor about strategies.
The most common reasons include: overtiredness (wake windows stretched too long), under-tiredness (naps too late or too long), sleep association dependency (needing a specific condition to fall asleep and then needing it again at each overnight light-sleep cycle), environmental disruption (light, noise, temperature), teething discomfort, developmental leaps (rolling, increased awareness), illness, or the 6-month sleep regression. Most disrupted sleep at this age has a recognisable and temporary cause. If disruption is severe, persistent beyond 4–6 weeks, or accompanied by other concerns, speak with your health visitor.
Most 6 month olds do well with a bedtime between 6:30pm and 8:00pm. The ideal bedtime is determined by working backwards from the last nap: after the final nap ends, add the last wake window (2 to 2.5 hours) to find the appropriate bedtime. If the last nap ends at 3:30pm, a 6:30–7:00pm bedtime is usually appropriate. An overtired baby who has missed their sleep window is often harder to settle — aim to start the bedtime routine at the first signs of tiredness, not after a battle to push past them.
At 6 months, individual naps typically range from 30 minutes to 2 hours. Short naps of 30–45 minutes are common and not always a problem — some babies naturally sleep in shorter cycles and wake fully rather than linking sleep cycles. If very short naps are consistently leaving your baby overtired, a longer pre-nap wind-down or a slightly earlier nap start may help. Very long naps that push bedtime very late can be gently capped by waking your baby — protecting overnight sleep pressure is more important than letting any single nap run indefinitely.
Most babies make the 3-to-2 nap transition between 6 and 9 months, with many doing so closer to 7–8 months. Signs that a baby is ready include: consistently refusing or fighting the third nap for a week or more, settling resistance at other nap times, earlier morning waking, or a third nap so late it pushes bedtime past 8pm. The transition is usually gradual — expect some 3-nap days and some 2-nap days during the transition before settling on 2 consistently.
Many do — particularly breastfed babies, who may still genuinely need 1–2 overnight feeds at 6 months. Breast milk digests faster than formula, and the caloric demands of a growing 6 month old are significant, especially in the early weeks of solid food introduction when solid amounts are very small. Formula-fed babies may not need overnight feeds by 6 months if taking adequate daytime volumes — but this varies by baby. Whether overnight feeds are nutritionally necessary for your specific baby is a question for your health visitor, who can assess based on weight and feeding patterns.
For most babies, starting solid foods does not immediately improve overnight sleep. The idea that a solid food meal before bed will help a baby sleep longer is a persistent myth not supported by the evidence. Solid foods at 6 months are introduced for developmental readiness, nutritional variety, and allergy management — not to improve sleep. Some babies experience mild digestive adjustment during initial food introduction that can temporarily disturb sleep. In the longer term, as solid food intake gradually increases over months, hunger-driven night waking may naturally decrease.
Common tired signs in a 6 month old include: rubbing eyes or ears, yawning, turning the head away from stimulation, staring blankly, becoming fussier or clingier than usual, losing interest in toys or play, or arching the back. By 6 months, many babies can mask tired signs well — they become engaged by their stimulating environment even when overtired. If your baby has been awake for close to 2.5 hours with no obvious tired signs, it is generally safer to begin the sleep routine anyway rather than waiting for clear signals.
Yes — teething typically begins around 6 months for many babies, and gum discomfort can disrupt both nap and overnight sleep. Signs of teething-related sleep disruption include increased drooling, chewing on everything, fussiness that isn't explained by hunger or tiredness, and redness or swelling along the gum line. Teething sleep disruption is usually most significant in the days before a tooth breaks through and resolves within a few days of the tooth appearing. If discomfort seems significant, your GP or health visitor can advise on age-appropriate pain relief options for your baby.
Contact your health visitor or paediatrician if: your baby is consistently sleeping fewer than 10 total hours per 24 hours; night wakings are so frequent that your own health is being significantly affected; disrupted sleep has lasted more than 4–6 weeks with no improvement; you notice any breathing irregularities during sleep (snoring, gasping, pausing); your baby seems unusually difficult to rouse during the day; or you have any instinctive concern that something isn't right. Most 6-month sleep disruption is normal — but your health visitor is the right person to help when it isn't.
The Bottom Line on 6 Month Old Sleep
Six months is a genuinely significant sleep moment — not because something is going wrong, but because so much is going right. Your baby is rolling, becoming aware, possibly teething, beginning solid foods, and doing enormous developmental work that plays out in their sleep. The disruption many families experience at this age is not a sign that sleep was broken; it is a sign that development is happening.
The numbers to hold: 12–16 total hours, 10–12 overnight, 2–3 naps, wake windows of 2–2.5 hours. These are ranges and guidelines — they describe what most 6 month olds need, not what every 6 month old must precisely achieve. Your baby's weight gain, awake-time behaviour, and settling ease tell you more about whether sleep is adequate than any single number can.
If things are hard right now, they will not be hard forever. Developmental sleep disruptions at 6 months are temporary. The most effective approach — holding the routine steady, protecting wake windows, sharing the nights where you can — is also the simplest. Most families find that sleep returns to its previous baseline once the developmental leap settles, often within 2–6 weeks.
And if you are struggling — truly struggling, in a way that is affecting your health or your family's wellbeing — please speak with your health visitor. That is exactly what they are there for. You do not have to manage this alone.
