You just brought your baby home. You are exhausted. And your baby has decided that 3 am is the perfect time to be wide awake and full of opinions.
Here is the truth: newborns do not have a body clock yet. Day and night mean nothing to them in those first weeks. But the good news — it does get better, and it follows a pretty predictable pattern.
This guide gives you a real, research-backed baby sleep schedule for every stage from birth to 12 months. You will know exactly how much sleep to expect, how many naps, when night sleep improves, and what to do when everything suddenly falls apart (because it will — at least once).
Quick answer - Most babies sleep 16–18 hours a day as newborns and gradually consolidate to 11–14 hours by 12 months. Longer night stretches typically begin around 4–6 months. Sleeping through the night consistently usually happens between 6 and 9 months — but every baby gets there on their own timeline.
Baby Sleep by Age — The Complete Schedule
Before anything else, here is the big picture. Every age group has a different sleep need, a different number of naps, and a different wake window, which is simply how long your baby can stay comfortably awake before needing to sleep again.
| Age | Total Sleep | Night Sleep | Naps / Day | Wake Window |
|---|---|---|---|---|
| 0–4 weeks | 16–18 hrs | 1–3 hr stretches | 4–5 | 45–60 mins |
| 1–2 months | 14–17 hrs | 2–4 hr stretches | 4–5 | 45–75 mins |
| 2–3 months | 14–16 hrs | 3–5 hr stretches | 3–4 | 60–90 mins |
| 3–4 months | 14–16 hrs | 4–6 hr stretches | 3–4 | 75–120 mins |
| 4–6 months | 12–16 hrs | 6–8 hr stretches | 3 | 1.5–2.5 hrs |
| 6–8 months | 12–15 hrs | 9–11 hr stretches | 2–3 | 2–3 hrs |
| 8–10 months | 12–15 hrs | 10–12 hr stretches | 2 | 2.5–3.5 hrs |
| 10–12 months | 11–14 hrs | 10–12 hr stretches | 2 | 3–4 hrs |

Keep in mind - These are averages across thousands of babies. A baby sleeping slightly more or less is usually perfectly fine — especially if they seem content, alert between naps, and are growing well.
Newborn Sleep — Weeks 0 to 4
Newborns sleep a lot — but rarely in long stretches. Most manage 1 to 3 hours at a time before hunger wakes them up.
This happens because newborns have tiny stomachs. Breast milk digests in about 90 minutes. The formula takes a little longer — around 2 to 3 hours. Either way, your baby gets hungry fast, and hunger beats sleep every time.
There is also no melatonin production yet. Melatonin — the hormone that signals night-time — does not kick in until around 3 months. Until then, your newborn genuinely cannot tell the difference between 2 pm and 2 am.
The Most Important Rule for Newborns: Watch the Wake Window
A newborn can only stay awake comfortably for 45 to 60 minutes. After that, they get overtired — and overtired newborns are much harder to settle than tired ones.
Watch the clock, not your baby's yawns. By the time yawning appears, you are already behind.
Common mistake - Keeping a newborn awake longer hoping they will sleep better at night. It does not work. Overtired babies release cortisol — a stress hormone — which makes falling asleep even harder. More awake time does not mean more night sleep at this age.
What a Newborn Day Actually Looks Like
There is no real schedule at this stage — just a loose pattern of feed, brief awake time, and sleep. You might see something like this:
- Feed → 30–45 minutes awake → sleep (1.5–3 hours)
- Repeat around the clock — 8 to 12 feeds in 24 hours is normal
- No difference between day and night yet
The goal right now is not a schedule. It is survival — for you and your baby both.
Baby Sleep Schedule — 1 to 3 Months
Around 6 to 8 weeks, something shifts. You will notice one slightly longer stretch of sleep starting to appear — often 3 to 4 hours — usually in the early part of the night. This is your baby's body clock beginning to develop.
This is the right time to start a simple bedtime routine. It does not need to be elaborate. Bath, feed, dark room, white noise — done consistently every evening — starts teaching your baby that night differs from day.
Sample Routine — 6 to 12 Weeks
- 7:00 am — Wake, feed
- 8:15 am — Nap 1 (after ~75 mins awake)
- 10:00 am — Wake, feed
- 11:15 am — Nap 2
- 1:00 pm — Wake, feed
- 2:15 pm — Nap 3
- 4:00 pm — Wake, feed
- 5:00 pm — Nap 4 (short — 30–45 mins)
- 6:30 pm — Feed, start bedtime wind-down
- 7:30 pm — Sleep
- Night — 2 to 3 night feeds expected — this is normal
Tip - Keep night feeds muted, dark and boring on purpose. No eye contact, no talking, no lights. Your baby needs to learn that night feeds are not social events.
Baby Sleep Schedule — 3 to 6 Months
This is when sleep starts to feel more human. Melatonin production kicks in around 3 months, and many babies begin sleeping 5 to 8-hour stretches at night. You might even get a full night's sleep — enjoy it, because the 4-month regression is coming.
The 4-Month Sleep Regression
Around 3.5 to 4.5 months, your baby's sleep cycles permanently change. They shift from simple newborn sleep patterns to more complex adult-like cycles — with lighter sleep stages in between.
The result: your baby now wakes between sleep cycles just like adults do. But unlike adults, they have not learned to put themselves back to sleep. So they call for you.
This is not a problem you caused. It is not something you did wrong. It is a completely normal developmental milestone — confirmed by sleep research at the National Institutes of Health. It usually lasts 2 to 6 weeks.
Sample Routine — 4 to 5 Months
- 7:00 am — Wake, feed
- 9:00 am — Nap 1 (after ~2 hrs awake)
- 10:30 am — Wake, feed
- 12:30 pm — Nap 2
- 2:00 pm — Wake, feed
- 4:00 pm — Nap 3 (short catnap — 30–45 mins)
- 5:30 pm — Feed
- 7:00 pm — Bedtime routine + last feed + sleep
- Night — 1 to 2 feeds expected
Baby Sleep Schedule — 6 to 9 Months
By 6 months, most babies are developmentally ready to sleep for longer stretches with no need for a night feed. Most now sleep 9 to 11 hours at night, and most have settled into two proper naps during the day.
The third catnap usually disappears around 6 to 8 months — often signalled by your baby refusing it consistently for a week or more.
This is also the age when sleep training — if you choose to try it — becomes a genuine option. The most comprehensive review on infant sleep training, published in the journal Sleep, found no negative effects on infant attachment, behaviour or development. That includes the Ferber method, the chair method and gentler fading approaches.
Sample Routine — 6 to 8 Months
- 7:00 am — Wake, milk feed
- 8:00 am — Breakfast (solids)
- 9:30 am — Nap 1 (45 mins–1.5 hrs)
- 11:00 am — Milk feed
- 12:00 pm — Lunch (solids)
- 2:00 pm — Nap 2 (1–1.5 hrs)
- 3:30 pm — Milk feed + snack
- 5:30 pm — Dinner (solids)
- 6:30 pm — Bedtime milk feed + sleep
- Night — Many babies drop night feeds at this age
Baby Sleep Schedule — 9 to 12 Months
Most babies this age sleep 10 to 12 hours at night and take two naps totalling around 2 to 3 hours. Night feeds are usually gone completely by now.
The 9-month sleep regression can still disrupt things, caused by the huge developmental leap of pulling up, cruising, and often crawling all at once. It usually lasts 2 to 6 weeks and then passes.
Around 11 to 12 months, some babies start showing signs that they are ready to drop to one nap. Signs include fighting the morning nap, taking a very long morning nap, then refusing the afternoon one, or becoming hard to settle at bedtime.
Nap transition tip - Most babies are not truly ready to drop to one nap until 14 to 18 months. Transitioning too early often creates an overtired baby who starts waking early and napping poorly. If in doubt — keep the two naps.
Sample Routine — 9 to 12 Months
- 7:00 am — Wake, milk feed
- 8:00 am — Breakfast
- 9:30 am — Nap 1 (~1 hour)
- 11:00 am — Milk feed
- 12:00 pm — Lunch
- 1:30 pm — Nap 2 (~1.5 hours)
- 3:00 pm — Snack + milk feed
- 5:30 pm — Dinner
- 6:30 pm — Bedtime milk feed + sleep
- Night — No feeds needed at this age
Sleep Regressions — Why Your Baby Suddenly Stops Sleeping
Sleep regressions are temporary periods when a baby who was sleeping well suddenly starts waking frequently again. They are not your fault. They are caused by developmental leaps — and they always end.
| Age | What Is Happening | Duration |
|---|---|---|
| 4 months | Sleep cycles permanently change to adult-like patterns | 2–6 weeks |
| 6 months | Separation anxiety begins — baby wakes wanting reassurance | 2–4 weeks |
| 8–9 months | Major developmental leap — crawling, pulling up, peak separation anxiety | 3–6 weeks |
| 12 months | First steps arriving, nap transition approaching | 2–4 weeks |

The best strategy during a regression: maintain your usual routine, offer extra comfort, and wait. Introducing major new habits during a regression — like feeding to sleep every time — tends to create problems that outlast the regression itself.
Safe Sleep — What Every Parent Needs to Know
The American Academy of Pediatrics and the NHS both recommend the same ABC framework for every sleep:
- A — Alone: Baby sleeps in their own safe sleep space, not in an adult bed
- B — Back: Always on their back — never front or side — until they can roll both ways independently
- C — Cot: A firm, flat mattress in a cot or crib with no soft bedding, pillows, bumpers or toys
Important - Room sharing — your baby in their own sleep space in your room — is recommended for at least the first 6 months and up to 12 months. It reduces the risk of SIDS by up to 50%, according to AAP research. Bed sharing is a separate thing and carries significantly higher risk.
Frequently Asked Questions
When do babies sleep through the night?
Most babies begin sleeping 6 to 8-hour stretches around 4 to 6 months. Sleeping a full 10 to 12 hours consistently usually happens between 6 and 9 months. Some perfectly healthy babies take until 12 months or beyond — and that is within normal range.
How many naps should my baby have?
Newborns nap 4 to 5 times daily. By 4 months, most are on 3 to 4 naps. By 6 to 8 months, most drop to 2 naps. The transition to 1 nap usually happens between 14 and 18 months — not at 12 months, despite what many people assume.
What is a wake window, and why does it matter?
A wake window is the maximum time your baby can comfortably stay awake before sleep pressure builds too high. Miss it, and you get an overtired baby — harder to settle, more night waking, and earlier morning wake-up. It sounds counterintuitive, but more awake time often means worse sleep.
Should I wake my newborn to feed at night?
For the first 4 weeks — yes, if they have not been fed in 3 hours during the day or 4 hours at night, wake them. After that, a healthy baby who is gaining weight well does not need waking. Let them lead.
What is the 4-month sleep regression?
Around 3.5 to 4.5 months, your baby's sleep architecture permanently matures. They enter lighter sleep stages between cycles — just like adults — but do not yet know how to transition through them independently. It is a sign of healthy brain development, not a sleep problem.
Does sleep training harm my baby?
No. The largest review of sleep training evidence — a 2016 meta-analysis in the journal Sleep — found that sleep training methods produce no negative effects on infant emotional health, behaviour or parent-child attachment. The evidence for safety is strong across multiple study designs.
Why does my baby fight sleep even when obviously tired?
Almost always — over-tiredness. When your baby passes their wake window, cortisol floods the system to keep them alert. Now they are wired and tired concurrently. The fix is catching sleep cues earlier, not later — and that usually means putting them down before you think they are ready.
Do I need a strict, timed schedule?
No. A flexible routine guided by wake windows and your baby's cues works better than clock-watching — particularly under 4 months. Consistency in the order of events matters more than exact timing. Bath, feed, sleep — same sequence, every night — is what builds the association.
