How to Start a Newborn Sleep Routine In Those First Few Months
When you’re in the blur of the fourth trimester, “newborn sleep routine” can feel a little out of reach.
Maybe your baby takes 20-minute naps some days and 2-hour naps the next. Maybe bedtime happens at 7pm or 11pm.
You’ve probably asked yourself one (or all) of the following:
Why does my baby hate the bassinet?
Do I really need a swaddle—and which one actually works?
Is she supposed to be napping this much… or this little?
What’s a normal bedtime for a newborn?
How can I stretch out those night sleeps just a little longer?
Honestly… very few parents experience predictable days or consistent sleep during the early weeks. And that’s okay.
The fourth trimester is a season of softness—of nourishing your baby, honoring your own recovery, and slowly finding your rhythm as a family. It’s a tender chapter of bonding and adjusting, where the days blur and the nights feel long… but it’s also a great time to lay gentle foundations for the kind of rest that serves everyone under your roof.
Even if everything feels a little upside down, your early efforts to support your baby’s sleep rhythms are powerful—and they do pay off.
Let’s talk about how to support your newborn’s sleep routine in a way that’s nurturing, science-backed, and gentle for everyone involved.
First, know this: Newborns don’t arrive with organized sleep patterns.
That’s because the circadian rhythm, the internal clock that regulates sleep and wake cycles, develops postnatally. With no circadian rhythm comes lots of day and night confusion. So if your baby seems to party at 3AM and snooze all afternoon, they’re not doing anything wrong. They’re adjusting.
The good news is there are simple ways to support your baby’s sleep patterns and help them move toward longer stretches of rest at night:
1. Align day and night cues.
Helping your baby distinguish between day and night will set them up for the best nighttime sleep possible.
Here are a few places to start:
Wake your baby to feed if it’s been three hours since their last feed. This helps “tank them up” during daylight hours, making sure their longest stretches of sleep happen at night instead of during the day.
Expose your baby to natural light in the morning. Take them outside or sit by a sunny window. Talk, sing, and play—your energy helps your baby associate daytime with activity.
Keep nighttime feeds dark and quiet. Use a red bulb or salt lamp and save conversation/stimulation for daytime.
Get outside during the day. Even a short stroller walk or time in the carrier can make a difference.
Aim to wake your baby at around the same time each day. A consistent morning rise sets the tone for more regular naps and bedtime windows.
Remember: newborns need to eat overnight. That’s developmentally appropriate.
2. Watch their wake windows.
Newborns are easily overstimulated, and overtired babies have a harder time falling and staying asleep.
That’s why in the newborn stage, I suggest focusing on wake windows—the stretches of time your baby can comfortably stay awake between naps.
Age-Appropriate Wake Windows:
1 Month — 35 to 60 minutes
2 Months — 60 to 90 minutes
3 Months — 75 to 90 minutes
Watch for sleepy cues:
Staring into space
Less engaged
Red eyebrows
Rubbing eyes
Yawning
Fussiness
If you catch these early cues, your baby is more likely to fall asleep calmly and sleep peacefully. If your baby is crying, rigid, arching their back, or making fists, it’s typically harder to help them transition into sleep.
3. Create a bedtime routine (yes, even now.)
Even a simple evening routine can help signal the difference between day and night. As early as you’d like, you can begin something like this:
Bath or wipe-down with a warm washcloth
Lotion and pajamas
Feed
Song or quiet cuddle
Lights out
Aim for bedtime between 8 and 10pm. It may feel late, but that’s biologically appropriate for a newborn. The consistency is what matters most, not the exact time.
4. Focus on full feeds.
Feeding and sleep are deeply connected. A hungry baby doesn’t sleep well, and a sleepy baby often doesn’t feed well.
That’s why I recommend gently encouraging your baby to stay awake during feeds, especially during the day. If your baby is having trouble staying awake during feeds, try:
Offering a feed right after they wake
Lightly dabbing a cool wipe on their forehead
Talking or singing to keep them engaged
Undressing them down to a diaper
Full bellies lead to better naps and longer stretches of overnight sleep. And those good pockets of rest lead to more alert, effective feedings. It’s a beautiful cycle!
5. Support sleep in and out of the crib.
Newborns don’t typically like the bassinet at first. It’s flat, firm, and lacks the cozy contact they’re used to.
But crib or bassinet sleep is important, not just for your baby’s long-term sleep skills, but for your own rest and recovery.
Here are some ways to help your baby adjust:
Use a swaddle to mimic the womb and minimize the startle reflex.
Hold upright for 5–10 minutes after feeding to release gas and improve comfort.
Try rocking or jiggling the bassinet gently to soothe them once laid down.
Use your scent by sleeping with the bassinet sheet before using it.
Spend time in the nursery during the day to build positive associations.
Lay them down on their side with a firm hand on their side before gently rolling them to their back.
6. Getting through the witching hours.
Between 5–11PM, many babies hit their fussiest stretch of the day — a phase often called the witching hours. And yes, it can feel long.
Why it happens:
They’re still adjusting to life outside the womb.
Milk supply naturally dips in the late afternoon and evening.
They’ve had a full day of sights, sounds, and stimulation.
What can help:
Protecting those afternoon naps to prevent overtiredness
Taking a warm bath or shower together
Soft lighting and a calm, quiet environment
Babywearing or stroller walks
Skin-to-skin time in a quiet space
Gentle burping, gas drops, or a diaper change
And if nothing seems to “work,” know this: your calm presence is the most powerful tool you have. You’re not doing anything wrong. Good babies cry.
By two months, your baby is probably ready for a newborn sleep routine that looks similar to this:
Consistent morning rise time
Feeds every 2–3 hours during the day
60-90 minute wake windows
Daily sunshine
Consistent bedtime routine
Consistent timing of bedtime (shifting closer to 8pm)
How long should a newborn sleep?
Newborns typically sleep 14–17 hours within a 24-hour period. Some may sleep a little more or less than that. In the early weeks, sleep usually happens in short stretches of 2–4 hours at a time because babies need to wake frequently to eat.
A newborn’s sleep schedule is unpredictable at first, and it’s normal for day and night sleep to feel mixed up as their circadian rhythm gets established. As they grow, your baby will start to develop a healthy newborn sleep routine.
Stick with the habits mentioned in this blog, and the whole house will get restful, consistent sleep.
But most importantly, take care of yourself.
Your well-being matters just as much as your baby’s sleep.
Don’t sleep on the benefits of babywearing when it comes to taking care of your own needs. Your breathing regulates theirs, they get some skin-to-skin time, and you get to move around or get out of the house. It’s a win-win!
Anchor your day with small rituals– your morning matcha, a midday shower, a short journal entry after your baby goes down. These moments create structure and care for you, too.
A hard day or night doesn’t mean you’re failing.
Your love and care are enough for your child.
Newborn sleep isn’t meant to be perfect, but it is meant to be supported. You don’t have to wait until you’re exhausted to ask for help, and you don’t have to figure it out alone.
