If your newborn sleeps all day and parties all night, you’re in very normal territory. Newborns sleep a lot, but in short pieces, and their sense of day and night takes weeks to develop. The first step toward easier nights is a safe sleep space, so start with our safe sleep checklist. Then use the gentle tips below to help your baby’s rhythm settle. This guide is part of our baby sleep guide by age.

How much do newborns sleep?

Newborns sleep about 16 to 17 hours a day, but they may only sleep 1 or 2 hours at a time (HealthyChildren.org). The NHS puts it slightly differently: total daily sleep “varies, but can be around 18 hours” (NHS).

That sleep is spread evenly across the day and night because tiny stomachs need frequent feeds. Breastfed babies commonly feed 8 to 12 times a day (HealthyChildren.org). There is no real newborn sleep schedule yet, and you don’t need one. Following your baby’s cues is the schedule for now.

AgeWhat sleep often looks like
Weeks 1–2Lots of sleep, short stretches, frequent feeds day and night
Weeks 2–6More alert periods; day/night mix-ups are common; fussy evenings
Weeks 6–12Some babies start linking a slightly longer stretch at night
3–6 monthsSome babies sleep 5–8 hours or longer at night, but not all (NHS)

Why won’t my newborn sleep at night?

There are three usual reasons, and none of them means you’re doing anything wrong.

  1. Hunger. Night feeds are normal and necessary in the early weeks. As the NHS puts it, babies wake during the night because they need to be fed.
  2. No body clock yet. Babies don’t have regular sleep cycles until about 4 months, so they drift in and out of light sleep easily.
  3. Day/night confusion. Some newborns bank their longest sleeps during the day and are wide awake at 2 a.m.

How to fix newborn day/night confusion

Newborn day/night confusion usually improves over the first weeks. The fastest way to help is contrast, an approach the AAP also recommends for reversing day-night reversal.

By day:

  • Open the curtains and let natural light in.
  • Chat, sing and play during awake time.
  • Let naps happen with normal household noise around, rather than in a silent, dark room.

By night:

  • Keep lights low, voices quiet and interaction minimal.
  • Focus on the essentials: feed, burp, change only if needed, back to bed.
  • Don’t start playing, even if your baby looks wide awake.

Safe sleep basics, right from night one

Safe sleep comes before any sleep tip. The AAP’s safe sleep recommendations are clear:

  • Back to sleep for every sleep, day and night.
  • Firm, flat surface in a crib or bassinet with a fitted sheet only, with no pillows, bumpers, blankets, toys or weighted products.
  • Room-share without bed-sharing, ideally for at least the first 6 months.
  • Avoid overheating. The UK’s Lullaby Trust recommends a room temperature of 16–20°C (about 61–68°F).
  • Never sleep with your baby on a sofa or armchair. If you feel yourself nodding off during a feed, put your baby back in their crib.

Swaddling: helpful, but only for a while

Swaddling can calm a startly newborn, but the AAP says to stop swaddling as soon as your baby shows any signs of trying to roll over, which can happen as early as 2 months. Always place a swaddled baby on their back, and keep the swaddle loose around the hips so the legs can bend up and out.

Is white noise OK for newborns?

Yes, used gently. Before birth, babies hear a constant whoosh of blood flow and a muffled heartbeat, so a soft, steady sound can feel familiar. In a small study, Spencer and colleagues (1990) found that 16 of 20 newborns (80%) fell asleep within five minutes with white noise, compared with 5 of 20 (25%) without it.

The key is volume and placement. Keep it around 50 dB or lower, about the level of a quiet conversation, and keep the device about 2 m (7 ft) from the crib, never inside it. When Hugh and colleagues (2014) measured 14 infant sleep machines at maximum volume, all of them exceeded 50 dBA at 30 cm, the noise limit recommended for hospital nurseries, and three exceeded 85 dBA. Distance and a low setting make a real difference. Read more in is white noise safe for babies.

Real previews from the app. Play them softly.

Many parents find womb and heartbeat sounds for newborns especially soothing in the first weeks. In the Baby Mantra app, womb sounds, heartbeat and white noise are all part of the free version, so you can try them tonight without an account.

A simple newborn bedtime routine

You don’t need a strict routine with a newborn, but a few repeated cues help from around 6–8 weeks:

  1. Dim the lights in the room about the same time each evening.
  2. Feed in a calm, quiet space.
  3. Change and swaddle or sleep-bag (stop swaddling once rolling starts).
  4. Start the same soft sound each night at a low volume.
  5. Lay your baby down on their back, ideally drowsy but still a little awake now and then, just for practice.

Keep it short, around 10–20 minutes. Over time, these cues become the signal that night has begun. As sleep cycles mature around 3 to 4 months, many parents meet the 4 month sleep regression, and this same routine is your best tool for it.

Look after yourself, too

Broken sleep is hard on parents. Sleep when you can, share night duties if possible, and accept help. If low mood, anxiety or intrusive thoughts last more than a couple of weeks, talk to your doctor, midwife or health visitor.
