Newborn Sleep Schedule (0–3 Months): A Week-by-Week Guide
Sleep deprivation in the newborn stage isn’t just exhausting — it’s disorienting. You’re watching the clock at 3am wondering whether this is normal, whether you’re doing something wrong, and when it gets better. Here is the most important thing to know first: analysis of over 1.2 million monitored babies found that median uninterrupted sleep stretches rise from 4.2 hours in the newborn stage to 7.5 hours by three to five months, reaching 8.8 hours by six to eight months. That will feel impossible at 2am with a three-week-old. The data says it’s coming.

Newborn Sleep Schedule by Week
Weeks 1–2: The Survival Stage
Total sleep: 16–17 hours per day | Wake windows: 45–60 minutes | Night feeds: Every 1.5–3 hours
In the first two weeks there is no schedule, and that is developmentally appropriate. The American Academy of Pediatrics recommends feeding on demand: every two to three hours for formula-fed babies, and whenever hunger cues appear for breastfed babies. Sleep Foundation data confirms the range here is genuinely enormous — anywhere from 11 to 19 hours per day is within normal.
Sleep cues to watch for: eye rubbing, yawning, staring blankly into the distance, pulling at ears, and becoming suddenly quiet and still. When you see two or three of these, begin settling immediately. An overtired newborn produces cortisol, which makes them considerably harder to settle than a baby caught at the right moment.
Weeks 3–4: The First Growth Spurt
Total sleep: 15–17 hours | Wake windows: 45–60 minutes | Night feeds: Every 2–3 hours
Week three typically brings the first growth spurt. Babies feed more frequently and seem impossible to settle for two to four days. This is temporary and it does not mean anything has gone wrong. Begin introducing one consistent sleep cue now — a white noise machine, a specific swaddle, or a short three-step sequence before each sleep. You are not sleep training. You are simply signalling to a developing nervous system that sleep is coming.
Weeks 5–6: Early Patterns Emerge
Total sleep: 15–16 hours | Wake windows: 60–75 minutes | Night feeds: 2–3 times
Around week six, many parents notice the first genuinely longer stretch at the start of the night — sometimes three or four hours. This is melatonin production beginning and your baby’s circadian rhythm starting to establish. Large-scale monitoring data confirms bedtimes gradually shift earlier through this period, moving from around 10pm toward 9:30pm. To support it: maximise bright light and activity during the day, and keep night feeds dark, quiet, and free of stimulation.
Weeks 7–8: Wake Windows Lengthen
Total sleep: 15–16 hours | Wake windows: 75–90 minutes | Night feeds: 2 times
By eight weeks, most babies handle 75 to 90 minute wake windows. A loose eat-play-sleep pattern can begin to emerge: after each feed, offer a short wake period that never exceeds the wake window, then begin settling before overtiredness arrives. This is responsive pattern-following rather than rigid scheduling.
Weeks 9–12: Progress Becomes Visible
Total sleep: 14–16 hours | Wake windows: 75–90 minutes | Night feeds: 1–2 times
The twelve-week mark is widely considered the turning point, and the monitoring data supports it: median uninterrupted stretches extend significantly during this window for most babies. A loose routine at twelve weeks might look like:
- 7:00am — Wake and first feed
- 8:30am — Nap one (45–90 minutes)
- 10:00am — Feed
- 11:30am — Nap two
- 1:00pm — Feed
- 2:30pm — Nap three
- 4:00pm — Feed
- 5:30pm — Optional catnap to prevent overtiredness at bedtime
- 6:30–7:00pm — Begin bedtime routine
- 7:30–8:00pm — Bedtime feed and sleep
- Overnight — One to two responsive feeds
Wake Windows by Age — Quick Reference
A wake window is the length of time your baby can comfortably stay awake between sleeps before overtiredness sets in. This is the single most useful number to know in the newborn stage.
- 0–4 weeks: 45–60 minutes
- 4–8 weeks: 60–75 minutes
- 8–12 weeks: 75–90 minutes
- 3–4 months: 90 minutes to 2 hours
- 4–5 months: 1.5–2.5 hours
- 5–6 months: 2–2.5 hours
- 6–8 months: 2.5–3 hours
The critical detail: always begin your settling process at the START of the wake window, not the end. By the time a baby shows overtired cues — hyper-alert, arching their back, inconsolable — you have already missed the optimal settling moment, and everything from that point is harder.
Feeding and Sleep
Breastfed newborns
Breast milk digests faster than formula, so breastfed babies typically feed every 1.5 to 2.5 hours in the early weeks. This is completely normal and does not indicate low supply.
Formula-fed newborns
Formula digests more slowly, so formula-fed babies often go 2.5 to 3.5 hours between feeds. This sometimes produces slightly longer first night stretches — but every baby is individual. Follow hunger cues rather than a rigid clock.
Dream feeding
Feeding your baby while they remain mostly asleep, usually around 10–11pm, to top them up before you go to bed. Widely recommended as a way of extending the first long stretch.
Cluster feeding
Most newborns cluster feed in the evening — every 30 to 60 minutes for two to four hours, typically between 4pm and 10pm. This is biologically normal, helps build supply, and peaks between weeks two and eight. It does not mean your milk is insufficient.
The Sleep Environment
- Room temperature: 16–20°C (60–68°F). Overheating is a recognised SIDS risk factor. Check the back of the neck, not the hands.
- White noise: Around 65 dB mimics the womb, which is louder than most people expect. Use a dedicated machine rather than a phone speaker.
- Darkness: Even newborns benefit from darkness during night sleeps. Use a red nightlight for changes — babies cannot detect red wavelengths, so it doesn’t stimulate them.
- Swaddling: Recommended from birth until your baby shows any sign of rolling, typically 8–12 weeks. Swaddling suppresses the Moro startle reflex that wakes newborns. Transition to arms-free the moment rolling begins.
- Safe sleep basics (AAP): always on the back, firm flat surface, nothing loose in the sleep space, room-share but do not bed-share for at least six months.
Common Sleep Challenges and What to Do
Day-Night Confusion
Many newborns arrive with their circadian rhythm reversed — sleeping long stretches in the day and waking to feed and socialise at night. The fix is consistent contrast: maximise light, noise, and engagement during daytime feeds, and keep night feeds dark, quiet, and brief. Do not engage in play after a night feed, however tempting the alertness is. This usually resolves within two to three weeks of consistent handling.
The Catnapping Baby
If your baby wakes reliably at 30 to 45 minutes into every nap, they are completing one sleep cycle and not yet transitioning into the next. At this age that is entirely developmentally normal, not a problem you have caused. You can attempt resettling with a shush-pat, or accept the short nap and adjust the rest of the day’s wake windows accordingly. Both are reasonable.
Overtiredness
An overtired baby produces cortisol, which makes falling and staying asleep considerably harder. The prevention is simple in principle and difficult in practice: always start the settling process before you think you need to. Watch wake windows rather than the clock, and err on the early side.
The Four-Month Sleep Regression
At around 3.5 to 4 months, sleep architecture changes permanently. Your baby begins cycling through sleep stages the way adults do, which means brief wakings between every cycle. They may not yet know how to resettle independently, so those brief wakings become full wakings. This is a developmental leap rather than a regression in the true sense, and it typically lasts two to six weeks. It passes.
When to Speak to Your Doctor
Contact your paediatrician or health visitor if your baby is consistently difficult to rouse for feeds, is not gaining weight as expected, has fewer wet nappies than usual, or if you have any concern about their breathing during sleep. Also reach out if you are struggling — parental exhaustion and low mood in the newborn period are common, treatable, and worth taking seriously.
Frequently Asked Questions
How many hours do newborns sleep?
Newborns sleep a total of 16 to 17 hours per 24-hour period on average, though the normal range spans 11 to 19 hours. Guidance from Children’s Hospital of Philadelphia puts this at roughly 8 to 9 hours during the daytime and about 8 hours at night, all broken into short periods of one to four hours.
When will my baby sleep through the night?
Analysis of over 1.2 million monitored babies shows median uninterrupted sleep stretches reaching 7.5 hours by three to five months, and 8.8 hours by six to eight months. Most babies consolidate to one or zero night feeds between four and six months, though individual variation is substantial. Some babies sleep through at three months; others not until after their first birthday. Both fall within normal.
Can I start a sleep schedule with a newborn?
Not a rigid one — that is not developmentally appropriate in the first four to six weeks. Gentle routines, however, help from around week four. Focus on wake windows rather than clock times, respond to tired cues, and use consistent sleep signals such as white noise and a swaddle. Formal sleep training, if you choose to do it at all, is generally not recommended before four to six months.
Is it normal for a newborn to wake every hour?
In the first two weeks, frequent waking is normal, particularly during growth spurts and evening cluster feeding. Beyond that, hourly waking around the clock is worth discussing with your health visitor or paediatrician — it can indicate reflux, feeding difficulties, or an environment issue such as the room being too warm or too cold.
Should I wake my newborn to feed?
In the first two to three weeks, most healthcare providers advise waking a newborn who sleeps longer than four hours to feed, particularly if weight gain is being monitored. Once your baby is back above birth weight and gaining steadily, your paediatrician will usually say you can let them sleep. Always follow the specific guidance you have been given for your baby.
