Newborn Sleep Schedule: What to Expect Week by Week (0–12 Weeks)

Newborns don't follow a set schedule — and that's normal. In the first 12 weeks, most babies sleep roughly 14–17 hours per 24 hours, but only in short stretches of 1–3 hours, waking every 2–4 hours to feed around the clock. Instead of watching the clock, follow age-appropriate wake windows (about 45–90 minutes for most newborns) and your baby's sleepy cues. A predictable, clock-based schedule usually doesn't emerge until closer to 3–4 months.

If you're reading this one-handed at 3am with a baby on your chest: you're doing fine. Here's what newborn sleep actually looks like, week by week.

Newborn Sleep at a Glance (0–12 Weeks)

Every baby is different, and healthy babies fall across a wide range. Use this table as a starting point, not a report card.

A "wake window" is the time your baby can comfortably stay awake between sleeps — and in the newborn stage it includes feeding, burping, and the diaper change. If that concept is new to you, our guide to decoding wake windows explains it in depth.

Weeks 0–4: The Fourth Trimester

In the first month, your baby sleeps most of the day — but rarely for long. Expect 1–3 hour chunks, day and night, with feeds every 2–3 hours. Day/night confusion is completely normal at this stage: your baby spent nine months in the dark and has no idea mornings exist yet.

What to focus on:

• Wake windows of 45–60 minutes, max. That's often just enough time for a feed, a burp, and a fresh diaper before it's time to sleep again.
• Feed on demand. Breastfed newborns typically eat 8–12 times a day, and evening cluster feeding is common and normal.
• Loose "eat, play, sleep" cycles. Even a minute or two of "play" (eye contact, a little tummy time) helps separate feeding from falling asleep — but don't force it.
• Don't chase a schedule. Right now your only jobs are feeding, safe sleep, and rest. Patterns come later.

Logging sleep and feeds — even roughly — helps more than you'd think at this stage. Not to control the chaos, but to see it. After a few days of tracking, most parents notice their baby already has loose rhythms hiding inside the randomness.

Wake windows are the stretches of awake time a baby can comfortably handle between sleeps — roughly 60-90 minutes for a newborn, extending to 2-4 hours by the first birthday. Keeping naps inside that window is the easiest way to prevent an overtired baby who fights sleep.

Weeks 5–8: Patterns Start to Emerge

Somewhere in the second month, many parents notice a first glimmer of order: one longer stretch of night sleep (often 3–5 hours, sometimes more), usually at the start of the night.

What to focus on:

• Wake windows stretch to 60–90 minutes. Watch for sleepy cues — yawning, red eyebrows, staring off — and start the wind-down before overtiredness hits.
• Start a simple bedtime routine. Something short and repeatable: dim lights, a feed, a song, into the sleep space. It's less about the steps and more about the signal: night is different from day.
• Fight day/night confusion with light. Bright, normal household noise and daylight during daytime feeds; dark, boring, and quiet at night feeds. Most babies sort out day and night by 6–8 weeks.
• White noise and a dark room can help naps and nights alike.

This is also peak fussiness territory for many babies — evening "witching hour" crying often ramps up around 6 weeks before easing off. If evenings are rough, you're not doing anything wrong.

Weeks 9–12: Longer Nights, More Predictable Naps

By the end of the third month, sleep often starts to consolidate. Some babies manage a 6–8 hour stretch at night; many others are still waking every 3–4 hours to feed. Both are within normal.

What to focus on:

• Wake windows of roughly 75–120 minutes, shortest before the first nap of the day.
• 3–5 naps per day, still varying in length — short catnaps are normal at this age.
• Practice "drowsy but awake" when it works. Putting your baby down sleepy but not fully asleep lays the foundation for independent sleep. If it fails at 3am, feed or rock them to sleep and try again another time. No single bedtime makes or breaks anything.
• An earlier, more consistent bedtime (often between 7–9pm) tends to emerge naturally as night sleep organizes.

If you want a quick answer to "when should the next nap be?", our free nap calculator estimates it from your baby's age and last wake-up time.

A Sample Day for an 8-Week-Old (Rhythm, Not Schedule)

Newborns aren't ready for set nap times, but a repeating pattern is realistic. Here's what a day might look like around 8 weeks — treat every time below as "give or take an hour."

The anchor points that matter most are a consistent-ish morning wake time and a repeatable bedtime routine. Everything in between flexes with your baby.

How Long Should a Newborn Sleep at Night?

Newborns typically get about 8–9 of their daily sleep hours at night — but broken into pieces, with feeds every 2–4 hours. Uninterrupted nights are not a newborn skill. The first sign of progress is usually one longer stretch (3–5 hours) at the beginning of the night, emerging sometime in the second month.

Should I Wake My Newborn to Feed?

In the early weeks, yes — most pediatricians advise waking a newborn to feed if they've slept more than about 3–4 hours, until your baby is back above birth weight and gaining steadily. After your pediatrician gives the green light, you can generally let your baby take whatever long stretch they'll give you at night. When in doubt, ask at your next checkup — this is a very normal question.

Why Does My Newborn Sleep All Day and Party All Night?

Day/night confusion. Babies aren't born producing melatonin on an adult rhythm, so their internal clock needs calibrating. Help it along by keeping days bright, noisy, and social (even during naps) and nights dark, dull, and quiet — feed and change with minimal lights and minimal chat. Most babies flip their days and nights around by 6–8 weeks.

When Will My Newborn Sleep Through the Night?

Sooner than it feels, later than you'd like. "Sleeping through the night" in research terms often means just a 5–6 hour stretch — and some babies do that by 3 months, while many perfectly healthy babies take much longer, especially breastfed babies who still need night feeds. Fair warning: many babies who sleep beautifully at 10–12 weeks hit a bump soon after. That's the 4-month sleep regression, and it's actually a permanent (and healthy) change in how babies cycle through sleep.

Is It Normal for Newborn Sleep to Be So Random?

Yes. Newborn sleep cycles are short (about 40–60 minutes), they spend more time in light, active sleep than adults do, and naps can range from 20 minutes to 2+ hours on the same day. Randomness in the first 6–8 weeks is not a sign you've created bad habits. There are no bad habits at this age — only survival strategies.

Safe Sleep: The Non-Negotiables

Whatever your schedule looks like, the AAP's safe sleep guidance applies to every single sleep, day or night:

• Back to sleep, every sleep — on their back, for naps and nights.
• Firm, flat sleep surface — a safety-approved crib, bassinet, or play yard with a fitted sheet only.
• Nothing else in the sleep space — no blankets, pillows, bumpers, or stuffed toys.
• Room-share, don't bed-share — the AAP recommends keeping baby's sleep surface in your room, ideally for at least the first 6 months.
• Stop swaddling at the first signs of rolling.
• Keep baby smoke-free and avoid overheating.

How Tracking Helps (Without Adding Pressure)

You don't need to track anything to raise a healthy baby. But when you're running on fragments of sleep, memory is unreliable — and patterns are invisible until you write them down.

Logging sleeps and feeds in MyBabyTracker takes a couple of taps, and the app uses your baby's age and last wake time to predict when the next nap is likely due — so you're not doing wake-window math at 3am. You can start tracking free with a MyBabyTracker account and have a week of real data before your next pediatrician visit.

When to Talk to Your Pediatrician

Newborn sleep is messy, but a few things warrant a call rather than a wait-and-see:

• Your baby is hard to wake for feeds, unusually floppy, or far sleepier than usual.
• Fewer wet diapers than expected, poor feeding, or concerns about weight gain.
• A rectal temperature of 100.4°F (38°C) or higher in a baby under 3 months — call right away.
• Loud, labored, or pause-filled breathing during sleep.
• Your baby is never calm or alert even briefly between sleeps, or something just feels off. Trust your gut — that's what checkups and nurse lines are for.
