Newborn Sleep Schedule Week by Week: The First 12 Weeks

In the first 12 weeks, a newborn sleep schedule is less a clock and more a rhythm: short bursts of sleep around the clock, gradually stretching as your baby grows.

If you are searching for a newborn sleep schedule week by week, you are probably running on very little sleep yourself and hoping for a plan. Here is the honest version: newborns do not follow a fixed schedule, and they are not supposed to yet. What they do follow is a slowly lengthening pattern of wake windows, and once you can read that pattern, the days start to make a lot more sense.

This guide walks through how much newborns sleep, wake windows week by week from birth to 12 weeks, sample flexible days for each stage, why newborn sleep feels so random, and the safe sleep basics that apply to every single nap and night.

How Much Do Newborns Sleep?

Most newborns sleep 14 to 17 hours in every 24, and in the very first couple of weeks some sleep even more. That total is spread across roughly two to four hour chunks, with feeds every two to three hours, because a newborn’s stomach is tiny and empties quickly. Reference studies of infant sleep show wide, healthy variation around these numbers, so a baby who sleeps a bit more or less can still be perfectly normal ¹.

The number that changes most over these 12 weeks is not total sleep, it is how that sleep is organized. Newborns start with sleep scattered evenly around the clock, then slowly begin to bundle more of it into the night. Here is the general shape of newborn sleep by stage:

Age	Total Sleep (24h)	Typical Sleep Periods
Weeks 1–2	15–18 hours	8–10 short sleeps
Weeks 3–4	15–17 hours	6–8 sleeps
Weeks 5–8	14–17 hours	4–6 naps plus night
Weeks 9–12	14–16 hours	4–5 naps plus longer night stretch

Newborn Wake Windows Week by Week

A wake window is the amount of time your baby can comfortably stay awake between sleeps, including the feed. In the newborn stage these windows are the single most useful tool you have, because they are far more reliable than the clock. Watch the window, catch the early sleepy cues, and you head off the overtiredness that makes newborns hard to settle.

Age	Wake Window
Weeks 1–2	30–60 minutes
Weeks 3–4	45–60 minutes
Weeks 5–8	60–90 minutes
Weeks 9–12	75–120 minutes

Because these windows are so short, a young newborn can easily cycle through eight to ten of them in a day. Sleepy cues to watch for include a still or glazed stare, slower movements, turning away from stimulation, yawning, and fussing. By the time a newborn is crying hard, they are usually already overtired, so aim to start winding down at the first quiet signs. For the full picture beyond the newborn stage, our wake windows by age guide shows how the day keeps stretching, and our newborn wake windows guide goes deeper on this stage.

Sample Newborn Schedules by Week (Flexible, Not Fixed)

These samples are rhythms to lean on, not timetables to enforce. Newborns feed on demand, and a hungry baby always comes before a clock. Think of these as the shape of a good day rather than a script.

Weeks 1 to 2

A cycle of feed, a short awake moment, then sleep, repeating day and night. Wake windows are only 30 to 60 minutes, so a newborn is often ready to sleep again shortly after a feed and a diaper change. Do not expect any day and night difference yet. Feed at least every two to three hours in the daytime, and follow your pediatrician’s guidance on waking to feed until birth weight is regained.

Weeks 3 to 4

The same feed, wake, sleep rhythm, with slightly more alert time. Many babies hit a fussy evening stretch now, often called the witching hour, and cluster feeding in the evening is common and normal. You can start planting the seeds of a day and night difference: bright and interactive by day, calm and dim for night feeds. Learn more about the evening fussiness in our witching hour guide.

Weeks 5 to 8

Wake windows stretch to 60 to 90 minutes, and naps begin to look a little more like naps, usually four to six of them. Some babies offer a longer first stretch of night sleep now. This is a good time to begin a short, consistent bedtime routine, since a predictable wind down is one of the most evidence backed sleep tools there is ³. Around this age many families start using our 1 month old sleep schedule as a next step.

Weeks 9 to 12

Wake windows reach roughly 75 minutes to 2 hours, and the day tends to settle into four to five naps with a clearer, longer stretch at night. Bedtime may start to drift earlier, into the evening, as the internal clock matures. This is the bridge into the more structured days ahead, covered in our 2 month old sleep schedule.

Why Newborn Sleep Feels So Random

A newborn’s sleep is scattered because the internal body clock, the circadian rhythm, has not switched on yet. In the womb there is no daylight or darkness to set it, so for the first weeks your baby genuinely cannot tell day from night. Their sleep hormone, melatonin, only begins to follow a day and night pattern around 8 to 12 weeks, which is why sleep often starts to consolidate near the end of this stretch.

You can gently nudge that clock along: get plenty of daylight and normal household activity during daytime feeds, and keep night feeds quiet, dim, and low key. Newborns also spend a large share of sleep in active sleep, a light, twitchy, noisy stage where they may squirm, grunt, or briefly stir without truly waking. It helps to pause before rushing in, since they often resettle on their own. Our guide on active sleep in newborns explains what is normal here.

Safe Sleep for Every Newborn Nap and Night

No matter how the schedule looks on any given day, the safe sleep rules never change. Follow them for every nap and every night, in line with American Academy of Pediatrics guidance ⁴:

• Always place your baby on their back to sleep, for naps and at night.
• Use a firm, flat sleep surface: a crib, bassinet, or play yard with a fitted sheet only.
• Keep the sleep space completely bare. No pillows, blankets, bumpers, or stuffed toys.
• Room share without bed sharing for at least the first 6 months. Keep the baby on their own separate surface.
• A swaddle can help in the early weeks, but stop swaddling at the first signs of rolling.

If you swaddle, our how to swaddle a baby guide walks through a safe, snug wrap that leaves room for the hips.

Gentle Ways to Support Newborn Sleep

You cannot sleep train a newborn, and you do not need to. What you can do is set up habits that make the coming months easier:

• Follow wake windows more than the clock, and start winding down at the first sleepy cues.
• Build a light and dark contrast between day and night to help the body clock along.
• Offer full feeds during the day so more calories land in daylight hours over time.
• Try laying your baby down drowsy but awake once in a while, with no pressure if it does not work yet.
• Protect your own rest where you can. Newborn sleep is a season, and it does pass.

When to Talk to Your Pediatrician

Newborn sleep is wonderfully variable, but check in with your pediatrician if your baby is very hard to wake for feeds, is not gaining weight as expected, sleeps far more or far less than the typical ranges, or if you notice breathing pauses, persistent noisy breathing, or feeding difficulties. If a newborn seems unusually sleepy or floppy, our guide on a sleepy newborn and when to worry can help you decide when to reach out. Trust your instincts: you know your baby, and a quick call is always worth it.
