My Newborn Won’t Sleep in Their Bassinet at Night
You finally got your newborn asleep.
You slowly stand up, carefully walk over to the bassinet, lower them down as gently as possible…
…and within seconds, their eyes pop open.
If this sounds familiar, you’re in good company. One of the most common things I hear from new parents is:
“Why will my newborn sleep on me but not in their bassinet?”
While newborns don’t have the cognitive ability to decide they dislike a specific sleep space, they do have very real biological reasons that make sleeping independently difficult in the early weeks.
Your baby spent nine months in a warm, snug, constantly moving environment. Now they’re expected to sleep flat, still, and alone. That is a huge adjustment!
There usually isn’t one single reason a newborn struggles with bassinet sleep. More often, it’s a combination of their developing nervous system, their need for comfort and regulation, feeding, sleep pressure, and learning the difference between day and night.
Let’s break down the most common reasons your newborn may be struggling with the bassinet.
Why Does My Newborn Only Sleep When I’m Holding Them?
One of the biggest reasons newborns prefer sleeping on a parent is because your body provides everything they were used to before birth:
warmth
movement
pressure
your heartbeat
your familiar scent
Your newborn’s nervous system is immature, and many babies rely heavily on external regulation. In simple terms: they often need help calming their bodies enough to fall asleep.
This is why some babies seem to “hate” being put down. They aren’t rejecting the bassinet, they’re missing the sensory input they’re used to.
Remember, your baby spent nine months being held tightly, surrounded by movement. The outside world is a big change!
ome babies adjust quickly to sleeping in a more open space, while others really need extra support while their nervous system develops.
This doesn’t mean you have created a bad habit.
Holding your newborn, rocking them, and helping them settle is developmentally appropriate.
You can help bridge that gap by:
using a snug swaddle (when your baby is not showing signs of rolling)
rocking or bouncing before sleep
wearing your baby during awake time
doing contact naps during the day to meet their sensory needs
Why Does My Newborn Wake Up When I Put Them Down?
Sometimes the problem isn’t the bassinet. It’s the transfer. Think about what changes when you move your baby from your arms to the mattress:
Your baby goes from warm to cool.
Moving to still.
Being held tightly to having more open space.
For some babies, that change is enough to wake them.
A few things that may help:
Wait until your baby is in a deeper stage of sleep before transferring, usually around 10–15 minutes after they fall asleep.
Lower them slowly, placing their feet down first, then their bottom, back, and finally their head.
Keep your hands gently on their body for a few moments after placing them down.
If needed, gently jiggle them with your hand on their chest to help them resettle.
Some parents also find it helpful to lower their baby onto their side and then gently roll them onto their back once they are on the mattress. Always make sure your baby ends up sleeping on their back on a flat, firm surface.
Could Gas or Reflux Be Keeping My Baby Awake?
If your baby seems perfectly content in your arms but becomes upset every time they are laid flat, it is worth considering whether discomfort is playing a role.
Some common reasons newborns may struggle include:
gas
reflux
muscle tension after birth
being too hot or too cold
needing to burp
an uncomfortable diaper
Things I watch for to evaluate if a baby has some discomfort:
Does your baby seem uncomfortable after every feeding? Do they arch their back? Are they much happier when held upright?
If you have concerns about reflux, pain, or feeding, bring those observations to your pediatrician.
A comfortable baby is much more likely to sleep well.
Will an Overtired Newborn Fight Sleep?
You have probably heard the phrase “sleep begets sleep,” and during the newborn stage, it is especially true.
Newborns can typically only handle short periods of awake time—often around 60–90 minutes between naps, depending on their age and individual needs.
When a newborn stays awake too long, they can become:
fussy
wired
difficult to soothe
harder to transfer
more likely to wake shortly after falling asleep
An overtired baby is not always an obviously sleepy baby.
Sometimes they look like they are fighting sleep when their body is actually struggling to settle.
That being said, this doesn’t mean every newborn who struggles in the bassinet is overtired. It’s just one piece of the puzzle.
Is My Newborn Waking Up Because They’re Hungry?
Feeding and sleep are closely connected during the newborn stage.
Many newborns are sleepy eaters. They may take small “snack” feeds throughout the day instead of full feeds, which can make it harder for them to get longer stretches of sleep.
Making sure your baby is feeding regularly and staying awake while feeding throughout the day can help support long stretches of sleep at night earlier on.
Many newborns need to feed about every 2–3 hours during the day, but always follow your pediatrician’s recommendations based on your baby’s individual needs.
How Do I Help My Newborn Sleep More at Night?
Another big reason newborn sleep can feel so unpredictable?
They are not born with a circadian rhythm.
That internal clock that helps us understand “day” and “night” develops gradually during the first several weeks of life.
This is why it is completely normal for a newborn to sleep more during the day and be more awake at night.
You can gently help their body begin learning the difference by:
Getting natural light during the day
Sunlight is one of the strongest signals for the developing circadian rhythm.
Even short periods of natural light exposure during the day can help your baby’s body begin recognizing when it is daytime.
Keeping daytime naps different from nighttime sleep
During the first 6–8 weeks, you don’t need to make every nap happen in a dark, silent room.
Allowing most naps to happen with normal household light and sounds can help create the contrast between day and night.
Avoiding extremely long daytime stretches of sleep
If your newborn takes very long naps during the day, you may need to wake them to feed and help encourage more opportunities for sleep at night. I’d avoid letting a single nap go much beyond 2.5–3 hours.
Is My Newborn Actually Awake, or Just a Noisy Sleeper?
One final thing that surprises many new parents:
Newborns are incredibly noisy sleepers.
They spend much more time in active sleep than adults do, which means they may:
grunt
wiggle
stretch
make faces
briefly open their eyes
without actually being awake.
Before immediately picking your baby up, try pausing for a couple of minutes.
You may discover they were simply moving between sleep cycles and didn’t need help at all.
Helping Your Baby Sleep In Their Bassinet
If your newborn won’t sleep in their bassinet, it does not mean your baby is a bad sleeper.
It also does not mean you are doing anything wrong.
Newborn sleep is unpredictable because your baby’s nervous system, feeding patterns, and internal clock are still developing.
The goal during this stage isn’t perfection. It’s learning your baby, supporting their needs, and understanding what may be making sleep harder.
