Newborns sleep 14 to 17 hours per day in short, irregular stretches of 2 to 4 hours. Their sleep is not yet organised around day and night, and they will not follow a real schedule for the first 8 to 12 weeks of life. What looks like chaos is biologically normal. The job in the first 12 weeks is not to enforce a schedule. It is to set up the habits that let a real schedule appear naturally once the body is ready.
How much do newborns actually sleep?
The short answer is "a lot, but not all at once."
Most newborns sleep between 14 and 17 hours per 24-hour period in the first month. The Sleep Foundation's newborn sleep guidance confirms this range and notes that some babies sleep up to 18 or 19 hours a day in the first weeks. The wide range is normal. There is no specific number you should be hitting.
The reason the sleep feels chaotic is that it does not come in one or two blocks. It comes in 6 to 8 separate sleeps, each lasting anywhere from 30 minutes to 4 hours. Some of those stretches are at 3am. Others are at 11am. There is no logic to it yet, because the part of the brain that controls when to sleep and when to wake (the circadian rhythm) has not finished developing.
This is the single most important thing to know about the first 12 weeks. Your baby is not "supposed to" be on any kind of consistent schedule yet. Their body literally cannot do it.
Why newborns don't have a "schedule" yet
Two systems control human sleep. Newborns have one of them and are still building the other.
The first is sleep pressure. This is the biological drive that builds up the longer you are awake. Newborns have this from birth, which is why they nap so often. As soon as they have been awake for 30 to 90 minutes, sleep pressure pushes them back down.
The second system is the circadian rhythm. This is the internal clock that organises sleep around day and night, makes you alert in the morning and sleepy at night, and produces the hormones (melatonin, cortisol) that drive that cycle. Newborns are born without a functioning circadian rhythm. It starts developing around 6 to 8 weeks and is reasonably mature by 12 to 16 weeks.
Until that internal clock is up and running, your baby will sleep whenever sleep pressure tips them over and wake whenever hunger or discomfort pulls them out. The "day vs night" distinction does not exist yet for them. This is why a healthy newborn can be wide awake at 2am and dead asleep at 2pm. They are not doing it to you. They genuinely cannot tell the difference.
The implication for parents is that you cannot force a schedule in the first 12 weeks, but you can do things every day that help the circadian rhythm develop faster. Those things are covered in detail further down.
Newborn sleep schedule by week (what to expect)
Below is a realistic week-by-week guide. Use it as a frame, not a prescription. Some babies sleep more, some sleep less, and almost none follow this exactly. The point is to see the trajectory.
Week 1
Total daily sleep: 16 to 18 hours
Wake windows: 30 to 45 minutes
Longest stretch overnight: 2 to 3 hours
The first week is almost entirely about feeding and sleeping. Your baby will be awake just long enough to feed and be changed, then back to sleep. Wake windows are barely a useful concept yet because the baby is essentially on a feed-sleep loop.
There is no separation between day and night at this stage. Your baby will sleep similar amounts at noon and at midnight. The longest stretches are usually 2 to 3 hours before hunger or discomfort wakes them.
Focus this week on feeding well, swaddling for sleep, and resting whenever you can. Do not try to teach anything yet. There is nothing to teach.
Weeks 2 to 3
Total daily sleep: 15 to 17 hours
Wake windows: 45 to 60 minutes
Longest stretch overnight: 3 to 4 hours
By the end of week 2, your baby is more alert during their wake periods. They are starting to hold eye contact, watch faces, and respond to voices. Sleep is still distributed evenly across the 24-hour cycle.
This is the stage where the "witching hour" often shows up, usually between 5pm and 9pm. The baby fusses, will not settle, and seems uncomfortable for no obvious reason. The most likely cause is overtiredness from a long wake window late in the day. The fix is shorter wake windows in the evening, sometimes as short as 30 minutes.
Our guide on how to calm a fussy baby goes deeper on the witching hour playbook.
Weeks 4 to 6
Total daily sleep: 14 to 16 hours
Wake windows: 60 to 90 minutes
Longest stretch overnight: 4 to 5 hours
Around the 4 to 6 week mark, the circadian rhythm starts to wake up. You may notice your baby starting to sleep slightly longer at night and being slightly more alert during the day. This is the first hint of organisation in their sleep.
Naps are still unpredictable. A 4 week old might give you a 30 minute nap followed by a 3 hour nap on the same day. This is normal. Do not try to extend short naps yet, your baby simply does not have the capacity to consolidate them.
This is the stage when establishing simple daily rituals starts to pay off. Bright light and stimulation in the morning. Dim lights and quiet from late afternoon onwards. A consistent wind-down routine before night sleep. None of this enforces a schedule. It helps the circadian rhythm find its rhythm.
Weeks 7 to 9
Total daily sleep: 14 to 16 hours
Wake windows: 75 to 100 minutes
Longest stretch overnight: 5 to 7 hours
This is where many parents first notice a real difference. The longest overnight stretch often jumps from 4 to 5 hours into the 5 to 6 hour range, sometimes longer. A surprising number of babies start giving their parents one solid block of night sleep between weeks 7 and 9.
Naps start to take shape. Most babies are on 4 to 5 naps per day, with the morning nap becoming the most predictable. The day starts to have rhythm: feed, awake window, nap, feed, awake window, nap.
If your baby is still only sleeping in your arms or on your chest, you are not alone. Contact napping is biologically normal at this age. Our piece on why your baby will not sleep without being held covers the transition into independent sleep.
Weeks 10 to 12
Total daily sleep: 14 to 15 hours
Wake windows: 90 to 120 minutes
Longest stretch overnight: 6 to 8 hours
By the end of the third month, most babies are sleeping noticeably longer at night and developing a pattern of 3 to 4 naps during the day. A daytime rhythm starts to emerge: a morning nap, a midday nap, a late afternoon nap, and bedtime.
This is also the stage where night feeds often start to drop. Some babies sleep through a 6 to 8 hour stretch without waking to feed. Others still need 1 to 2 night feeds. Both are normal.
By the end of week 12, you are on the edge of the 4 month sleep regression, which is a permanent change in how your baby sleeps. We cover that in detail in our guide on the 4 month sleep regression.
How to help your newborn sleep better
You cannot make a newborn sleep on a schedule. You can do five things every day that make their sleep less chaotic and help their circadian rhythm develop faster.
Watch wake windows, not the clock
In the first 12 weeks, wake windows beat clock-based scheduling every time. A wake window is the amount of time your baby can comfortably stay awake between sleeps before becoming overtired.
For newborns, that window is short. 30 to 60 minutes in the first month, building to 90 minutes by 12 weeks. Watch the time your baby last woke up and start the wind-down before they hit the end of the window. Our full wake windows by age guide is the foundation document for this.
The reason wake windows matter more than the clock at this stage is that newborn sleep is too variable for a clock schedule to work. A baby who slept from 8am to 9:30am needs to be down again by 10:30am. A baby who slept from 8am to 11am can stay up until lunch. The clock cannot tell the difference. The wake window can.
Master the wind-down
Newborns do not just fall asleep when they are tired. They need a transition. A 5 to 10 minute wind-down before every sleep dramatically improves how fast they settle.
A simple wind-down for naps: move to a dim room, swaddle, white noise on, gentle rocking or patting for a few minutes, then place down. For overnight sleep, you can extend this with a feed, a nappy change, and a slightly longer cuddle.
The exact routine matters less than the consistency. Babies learn cues fast. If the same things happen in the same order before every sleep, your baby's brain starts predicting sleep within a week.
Use the swaddle from day one
Swaddling is the single highest-leverage habit you can build in the first 12 weeks. A properly swaddled newborn settles faster, sleeps longer, and wakes less often than an unswaddled one. The reason is biological: swaddling contains the startle reflex (also called the Moro reflex) that otherwise wakes newborns up the second they are put down.
Our full step-by-step guide to swaddling a newborn covers the technique and the safety rules. If you want to skip the folding and use a purpose-built swaddle, our LullaWrap™ was designed for the parent doing this at 3am who just needs it to work.
The swaddle stays in place until your baby shows the first signs of rolling, usually between 8 and 16 weeks. At that point, it goes.
Set up the sleep environment
Newborn sleep gets dramatically better with three environmental tools in place: dark room, white noise, and consistent temperature.
A dark room helps the developing circadian rhythm recognise sleep time. Use blackout blinds for naps and overnight. The room should be dark enough that you can only just see your hand in front of your face.
White noise replaces the constant low-frequency rumble your baby heard in the womb. Continuous pink or brown noise at around 50 to 60 decibels from at least 2 metres away from the cot is the right setup. Our LullaHush™ portable white noise machine was built for this exact use case.
Room temperature should sit between 20 and 22 degrees Celsius (68 to 72 Fahrenheit). Too warm is more disruptive to sleep than too cool.
Eat, play, sleep (with caveats)
The "eat, play, sleep" routine is widely recommended for newborns. The idea is to feed your baby right when they wake up, then have a short awake window, then put them down for a nap (rather than feeding them to sleep and creating a feeding-to-sleep association).
The intent is sound and the routine works for many families. Two caveats:
First, do not stress if your baby falls asleep during a feed. Newborns do this. It is not a bad habit you are creating, it is biology. Cluster feeds in particular often end with a sleeping baby. Just put them down and move on.
Second, "play" for a newborn does not mean toys and stimulation. It usually means a nappy change, a short tummy time session, and some quiet time being held. That is plenty.
Day-night confusion: what it is and how to fix it
Around 30 to 50 percent of newborns have what is called day-night confusion in the first weeks. They sleep deeply through the day, then become alert and wakeful at night. This is exhausting and entirely normal.
The cause is the immature circadian rhythm. Without a functioning internal clock, the baby does not yet know that night is for sleeping. The fix is to give the developing rhythm strong daily cues that anchor day and night.
During the day: Keep the house bright. Open the curtains. Talk normally during feeds and changes. Do not whisper or tiptoe. Take your baby outside for 20 to 30 minutes of daylight exposure when possible, even on overcast days. Daylight is the strongest signal to the developing circadian rhythm.
During the night: Keep the house dim. Use a small night light during feeds rather than the main bedroom light. Minimise talking during night wakes. Change nappies only when necessary. Make the contrast between day and night as sharp as possible.
Most babies sort out day-night confusion by 6 to 8 weeks. Some take a bit longer. Consistent daytime light exposure is the single biggest accelerator.
When to expect longer night stretches
Almost every parent of a newborn is asking the same question: "When will they sleep through the night?"
The honest answer is that the first 4 to 5 hour stretch typically appears between 6 and 10 weeks. The first 6 to 8 hour stretch typically appears between 10 and 16 weeks. Genuine "sleeping through the night" (a 10 to 12 hour overnight without feeds) usually appears between 4 and 7 months, sometimes later.
The factors that bring it forward are: appropriate daytime feeding, consistent wind-down, optimal sleep environment, and managing wake windows so the baby is not overtired at bedtime.
The factors that push it back are: chronic overtiredness, irregular daytime schedule, frequent disruptions at night that prevent the baby from learning to link sleep cycles, and underlying issues like reflux or allergies.
There is wide natural variation. A baby who sleeps through at 10 weeks is not a "better sleeper" than one who does not until 6 months. Both are within normal.
Safe sleep basics for the newborn stage
These are non-negotiable. Every newborn sleep, naps and overnight, follows the same rules.
On their back. Always. Never on the side, never on the stomach.
On a firm, flat surface. A cot, bassinet, or moses basket with a firm mattress. No inclines, no wedges, no pillows, no positioners.
Alone in the sleep space. No loose blankets, no bumpers, no soft toys, no extra layers. A correctly fitted swaddle or a wearable sleep bag is the right amount of cover.
In your room, but not in your bed. Most paediatric guidance recommends room-sharing (baby's cot in the parents' room) for the first 6 months, but not bed-sharing.
Room temperature 20 to 22 degrees Celsius. Dressed appropriately for the temperature, never overheated.
Pacifier (dummy) at sleep onset is fine. It does not need to be replaced if it falls out.
The American Academy of Pediatrics safe sleep guidance covers all of this in detail and is the canonical source.
What to do when nothing is working
There is always a stretch in the first 12 weeks where nothing seems to be working. Wake windows are wrong, naps are 20 minutes, nights are broken, and you have not slept more than 90 minutes in a row in a week.
When you hit that wall, the playbook is short and works for most situations.
Reset the day. Wake your baby up at the same time tomorrow morning. Expose them to bright light. Start the first nap on the early end of the wake window. Run the day in the rhythm you want, even if last night was a disaster.
Shorten the wake windows. If naps are short and bedtime is a fight, your baby is almost certainly overtired. Pull the wake windows in by 15 to 20 minutes for a few days and see what happens.
Strengthen the wind-down. A longer, more consistent wind-down works better than a shorter one. Five extra minutes of rocking with white noise on can be the difference between a 30 minute nap and a 90 minute nap.
Get one tool that does one job. A baby who needs steady patting to settle does not need a parent's hand for 40 minutes per nap. Tools like our LullaBear™ take over the rhythmic patting so the parent can put the baby down and walk away. This is what makes the daily rhythm sustainable.
Accept that some days are bad. Newborn sleep is not linear. A baby who slept 6 hours straight on Monday may sleep in 90 minute chunks on Tuesday. This is not a regression or a failure. It is biology.

Frequently asked questions
How many hours should a newborn sleep at night?
Newborns do not have a clear "night" yet. In the first 4 weeks, expect 8 to 10 hours of total sleep across the night period, broken into 2 to 4 hour stretches with feeds in between. By 12 weeks, most babies sleep 9 to 11 hours overnight with 1 to 3 feeds.
Is it okay if my newborn sleeps more than the average?
Yes, in most cases. Some newborns sleep up to 18 to 19 hours a day in the first few weeks. As long as your baby is feeding well, gaining weight, and meeting growth milestones, longer sleep is normal. If your baby is consistently hard to wake for feeds or is missing feeds, talk to your pediatrician.
Should I wake my newborn to feed?
For the first 2 to 3 weeks, yes. Most pediatricians recommend waking your baby every 2 to 3 hours during the day and every 3 to 4 hours overnight until they regain their birth weight and feeding is well established. After that, most babies can be left to wake for feeds on their own.
Can I put my newborn on a strict schedule?
You cannot, and trying to force one usually makes things worse. The newborn brain is not yet capable of following a strict schedule. Focus on rhythms and wake windows for the first 12 weeks, then introduce a more structured schedule from 3 to 4 months onwards.
When does the witching hour stop?
For most babies, the witching hour (extended evening fussiness, usually 5pm to 9pm) peaks around 6 to 8 weeks and resolves by 10 to 12 weeks. Managing wake windows in the late afternoon is the most effective way to reduce it.
How long should my newborn nap?
Newborn naps vary widely, from 30 minutes to 3 hours. Both are normal. Do not try to extend short naps in the first 12 weeks. Just put them down for the next nap when the wake window ends.
Why does my newborn fight sleep when they are clearly tired?
Almost always overtiredness. By the time a newborn is showing late sleep cues (yawning, eye rubbing, fussing hard), the wake window has already been too long and overtiredness has set in. Watch for early cues (glazed stare, slow blinking, calm body) and start the wind-down earlier.
Is it safe for my newborn to nap in a swing or bouncer?
Brief, supervised naps in a swing or bouncer are generally fine, but the majority of sleep should happen on a firm, flat surface on their back. Inclined sleep is not recommended for unattended or prolonged sleep.
How do I know if my newborn is getting enough sleep?
A reasonably-rested newborn has alert wake windows, feeds well, gains weight steadily, and settles for sleep within a reasonable wind-down period. An undertired or overtired newborn fights sleep, has shorter naps, and gets fussier across the day.
The bottom line
Newborn sleep is not supposed to be on a schedule for the first 8 to 12 weeks. Your baby is not failing, you are not failing, and there is nothing to fix that biology has not already planned to fix on its own.
The job in the first 12 weeks is to build the habits and the environment that let a real schedule appear naturally when the brain is ready. Wake windows over the clock. Consistent wind-down before every sleep. Swaddle from day one. Dark room, white noise, the right temperature. Bright daylight in the morning, dim quiet at night.
Get those five things in place and most babies start showing real sleep patterns by week 8 to 10. Almost all do by week 12 to 14. Until then, the goal is survival and consistency, in that order.
