The first three months with your baby are beautiful, chaotic, and exhausting, often all in the same hour. If you're googling newborn sleep schedule at 2 AM while your baby treats night time like party time, you're not alone.
The honest truth: in the first 6 weeks, there is no schedule. Your newborn's sleep is driven by hunger and biology, not the clock. This guide covers newborn sleep patterns from birth to 3 months, with wake windows by week, sample routines, and practical strategies for day/night confusion, all following Red Nose Australia and Tresillian guidelines.
In the first three months, your baby has no circadian rhythm and doesn't produce melatonin in a day-night pattern. Sleep happens in short bursts of 2–4 hours around the clock, your baby isn't broken, this is how newborn biology works.
A newborn sleep schedule isn't something you impose. It's something that gradually emerges. Your job in the first few weeks is to learn your baby's cues, keep them safe, and survive.
Wake windows are how long your baby can comfortably stay awake between sleeps. In the newborn stage, these windows are incredibly short, and they include feeding time.
Tired signs: eye rubbing, yawning, staring, jerky movements, grizzling, turning away. Catching the window before your baby becomes overtired makes settling dramatically easier.
Overtired vs undertired: An overtired baby is harder to settle, they may cry, arch their back, and seem wired. An undertired baby simply isn't ready. If settling takes more than 20 minutes, try again in 10–15 minutes.
A newborn routine isn't a clock-based schedule, it's a flexible pattern following your baby's natural rhythms. Week by week, a structure starts to take shape.
Around 6–8 weeks, something changes. Your baby may start sleeping slightly longer stretches at night and tired signs become more predictable. This is when melatonin production begins, social smiling emerges, and stomach capacity increases, all nudging your baby toward a loose rhythm.
Tresillian's advice: This is the ideal time to introduce a simple bedtime routine, bath, feed, swaddle, cuddle, bed, in the same order at roughly the same time each evening. Keep it short (15–20 minutes) and calm.
By 2–3 months, wake windows extend to 60–90 minutes and night sleep may consolidate, some babies manage one 4–5 hour stretch. Morning naps (about 1–1.5 hours after waking) are often the best nap of the day. Expect 4–5 naps per day, dropping to about 4 by 3 months. The 3-month growth spurt around 12 weeks brings temporary disruption, cluster feeding, fussiness, disrupted sleep, but it passes.
Feed-play-sleep is a simple pattern: when your baby wakes, feed first, then a short play period, then settle for sleep. This prevents the feeding-to-sleep association that becomes harder to undo at 3–4 months.
In the newborn stage, cycles often look like feed-play-sleep-play-feed. It's messy, and that's fine. For more on settling techniques, see our responsive settling guide.
If your newborn treats 3 AM like party time, that's day/night confusion, completely normal and fixable. Most babies sort it out naturally between 6–12 weeks. Speed it up with these strategies:
Safe sleep is non-negotiable. Always place your baby on their back, on a firm flat mattress, in their own cot, with no loose bedding, pillows, or toys. Room share (not bed share) for at least 6 months. For the complete safe sleep checklist, see our Safe Sleep & SIDS Prevention Guide.
Newborn naps are naturally short, 20–50 minutes is one sleep cycle. That's normal. As your baby approaches 3 months, try resettling at the first stir. Sometimes it works, sometimes it doesn't.
Newborns crave contact, they just spent 9 months being held 24/7. Wait until deep sleep (limp arms, ~20 minutes) before attempting a cot transfer. Warm the cot first, keep a hand on their chest, and try again if they wake.
Grunting, snorting, and whimpering in active sleep are normal. Wait 30–60 seconds before picking them up, many parents accidentally wake their newborns by responding to normal sleep noises.
The right swaddle keeps your baby snug and secure, and makes settling so much easier. We've tested the best options available in Australia.

Newborns have sleep cycles of 50 to 60 minutes and can't link one to the next yet. They surface into light sleep and most wake fully instead of drifting through. It's brain development, and it takes time. In the 0 to 3 month window, catnaps are entirely normal. They only become something to work on after about 4 months.
Three things that sometimes help:
Red Nose Australia safety note: always place your baby back in their own safe sleep space: a firm, flat cot mattress with no pillows, bumpers, or loose bedding. Never leave a sleeping baby on a couch or bouncer. For settling approaches, see our guide to responsive settling techniques.
If your baby turns into a crying, cluster-feeding mess every evening between 5 PM and 11 PM, you're in the witching hour. It affects most newborns, peaks around 6 to 8 weeks, and it's not something you've done wrong: it's a developmental phase, not a sleep problem.
The cause isn't fully understood, but a few things work together: an immature nervous system overloaded by day's end, overtiredness from short newborn naps, and cluster feeding as an instinctive way to boost milk supply.
Three ways to survive it:
The witching hour fades by 8 to 10 weeks and resolves by 12 weeks for most babies. If crying lasts more than 3 hours a day or comes with feeding difficulties, see your GP. Free help: Tresillian 1300 272 736 or Karitane 1300 227 464.

Thirty to 45 minutes at weeks 0–2, 45–60 minutes at weeks 2–4, 60–75 minutes at weeks 4–8, and 60–90 minutes at weeks 8–12. These include feeding time. The most reliable guide is your baby's tired signs, eye rubbing, yawning, staring, grizzling, not the clock.
Expose your baby to morning sunlight, keep daytime bright and active, keep night feeds dark and boring (no talking or eye contact), and start a simple bedtime routine from 6–8 weeks. Most babies sort this out naturally by 12 weeks.
When your baby wakes, feed first, then a short play period, then settle for sleep. The goal is to avoid feeding to sleep every time, it's messy in the newborn stage and that's fine.
Newborns typically sleep 14–17 hours total, broken into short bursts of 2–4 hours driven by hunger. If your baby is feeding well, gaining weight, and has alert periods, their sleep is likely fine.
