Newborn sleep patterns: What to expect in the first few months

If there’s one topic that dominates every new parent’s life, it’s sleep—or the lack of it! Those early weeks and months can feel like a whirlwind of late-night feeds, unpredictable wake-ups, and questions about whether your baby is sleeping enough. Understanding newborn sleep patterns can be a game-changer. While no two babies are exactly the same, knowing what’s within the range of normal can help you approach those sleepless nights with a little more confidence and peace of mind.

In this guide, we’ll explore what you can expect from your newborn’s sleep in the first few months, how to navigate their evolving patterns, and simple tips to gently encourage healthy habits while still honoring their developmental needs.

What makes newborn sleep unique?

Newborn sleep is vastly different from what you might expect based on adult or older baby sleep cycles. In their first months, newborns:

  1. Sleep in short cycles of about 45-60 minutes, alternating between light (active) and deep (quiet) sleep.

  2. Spend about 50% of their sleep in active sleep (similar to REM), where they twitch, grunt, and even cry out while still being asleep.

  3. Have no established circadian rhythm (internal body clock), which means they don’t distinguish between day and night yet.

  4. Can really only tolerate 45-60 minutes of awake time between sleep times before they become overtired.

  5. Have a strong moro reflex that causes them to jolt or twitch if they get the sense they are falling, which can significantly impact their sleep.

These characteristics are perfectly normal and essential for their growth and brain development. Understanding these quirks can help you respond to your baby’s needs with more patience and less frustration.


Month-by-month guide to newborn sleep patterns

Month 1: Survival mode

  • What to expect: Your baby will sleep for about 14-17 hours a day, divided into short naps and short bursts of night sleep. Most wake periods are brief (30-60 minutes), and feedings will dominate their schedule. It’s not unusual to feel like they wake up long enough to feed and then are ready to sleep again almost immediately.

  • Common challenges: Day-night confusion is typical, as your baby’s circadian rhythm hasn’t developed yet. Expect frequent wake-ups at night—sometimes every 1-3 hours for feeding.

  • Tips:

    • Keep nighttime interactions calm and quiet to gently reinforce that nights are for sleeping.

    • Use bright light during awake time in the day to help differentiate between day and night.

    • Don’t worry if sleep feels unpredictable—this is completely normal at this stage.

    • Unless your pediatrician has said you need to wake your newborn to feed overnight, let them sleep.

    • Swaddling can help reduce the Moro reflex, allowing your baby to stay asleep longer.

Month 2: Finding a rhythm (sort of)

  • What to expect: Around 6-8 weeks, some babies start consolidating sleep into longer stretches at night (3-4 hours), and wake windows may lengthen slightly (up to 75 minutes). Nap patterns may still feel inconsistent, but your baby is beginning to show more defined sleepy cues.

  • Common challenges: Growth spurts or increased alertness can lead to fussier periods and shorter naps. The witching hour can also be a hard period of time each day. Usually happening between 5pm and 10pm, it’s not unusual for your newborn to be especially fussy and inconsolable at times during this time frame.

  • Tips:

    • Start introducing a simple bedtime routine to signal that sleep time is approaching.

    • Watch for signs of overtiredness (e.g., fussiness or rubbing eyes) and aim to settle your baby to sleep before they reach this point.

    • Use white noise and a dark room to your advantage as they become tired but fight sleep.

    • When you’re experiencing the witching hour, get your newborn outside for a walk as that can make a huge difference.

Month 3: Building better habits

  • What to expect: Many babies begin sleeping longer periods at night—some reaching a 5-6 hour stretch! Wake windows extend further (90 minutes or slightly more), and naps may begin to fall into a more predictable rhythm.

  • Common challenges: Your baby’s increased awareness of their surroundings can make it harder to settle them for sleep, especially if their environment is stimulating. This is also where I find parents start to lose steam and reach the end of their rope if their current sleep habits aren’t sustainable.

  • Tips:

    • Stick to a consistent bedtime and nap schedule as much as possible.

    • Offer naps in a dark, quiet room to reduce distractions.

    • Don’t be surprised if naps on the go start to be less effective and less restorative.

    • Introduce gradual self-settling techniques, like pausing briefly when your baby stirs before intervening.

Month 4 and beyond: Transitioning out of newborn sleep

  • What to expect: Around the 4-month mark, your baby’s sleep cycles begin to mature, and they may enter the infamous 4-month sleep regression. Their sleep cycles will drastically change and your baby will go from having 2 stages of sleep to having 5 stages of sleep. This disruption and change can lead to more periods of light sleep and therefore more potential for wake ups. 

  • Common challenges: More frequent night wakings or shorter naps may occur as your baby’s brain undergoes developmental leaps.

  • Tips:

    • Maintain the consistency you’ve built in their routine, as this will help your baby adjust more easily.

    • Offer extra comfort as needed during this period, but avoid creating new sleep associations that you don’t want to maintain long-term.

    • Hold your baby to their personal best overnight and try not to add in extra feeds that they’ve already shown you they don’t need.


Common newborn sleep myths debunked

1. “You can spoil a newborn with too much holding or rocking.”
False! Newborns thrive on close contact and comfort. Holding or rocking your baby to sleep during these early weeks helps them feel secure and loved—it’s not creating “bad habits.”

2. “Newborns should sleep through the night by 3-4 months.”
While some babies may begin sleeping longer stretches by this age, it’s not a universal milestone. Night wakings and night feedings are still developmentally appropriate for many newborns and babies under 6 months.

3. “It’s too early to teach your baby healthy sleep habits.”
Not true! While newborns aren’t ready for formal sleep training, you can still gently encourage healthy habits, such as maintaining a bedtime routine, creating a sleep-friendly environment, respecting their wake windows, and gradually working on independent sleep skills through exposure and low-key practice.

4. “Newborns don’t need a dark room for sleep.”
While newborns don’t yet have a fully developed circadian rhythm, a dark environment helps reduce distractions and creates a calming atmosphere for sleep. Over time, it can also support the development of their internal body clock. Plus, it helps build the pattern for them that a dark room means it’s time to get ready for sleep.

5. “If my baby is fussing, grunting, or moving around in the night, I need to tend to them ASAP.”
Not necessarily! Many newborns make a lot of noise in their sleep due to active sleep cycles. It’s okay (and actually recommended) to pause and assess whether your baby truly needs you before rushing to intervene. They may still be asleep and your intervention may accidentally wake them up. Or they may be awake but figuring out how to go right back to sleep without needing your help. Pausing and being curious is always helpful when it comes to newborn sleep- it’s how you learn more about your baby.


How to navigate newborn sleep patterns

Respect their wake windows
Newborns can only tolerate being awake for short periods, usually 45-90 minutes depending on age. Watch for sleepy cues, like yawning or rubbing eyes, and aim to settle them before they become overtired.

Create a sleep-friendly environment
Dark rooms, white noise, and a safe sleep space (like a crib or bassinet) can help your baby settle more easily. Remember the ABCs of safe sleep: Alone, on their Back, in a Crib.

Encourage day-night differentiation
Expose your baby to natural light and active play during the day, and keep nighttime interactions low-key, quiet, and dark. Over time, these cues can help your baby’s circadian rhythm develop.

Be flexible
Newborn sleep is anything but predictable. Instead of stressing over exact nap times or lengths, focus on ensuring your baby gets enough sleep across the day and night. Instead of worrying about the exact number of hours they are sleeping, pay attention to their mood and whether they seem rested or tired and crabby.


When to seek support

While sleep disruptions are normal in newborns, there are times when extra support may be helpful. Consider reaching out to a sleep consultant if:

  • Your baby consistently struggles to sleep despite your efforts.

  • Your baby is clearly exhausted and overtired but you can’t figure out how to break the cycle.

  • You feel overwhelmed or exhausted by your baby’s sleep patterns  and know you can’t continue with your current sleep habits.

  • You’d like personalized guidance to navigate your baby’s unique needs.
