Why Your Baby Won’t Sleep
(And It’s Not Your Fault)
If you’re here, you’re probably tired.
Confused.
Maybe even wondering what you’re doing wrong.
Let me say this first-
You are not the problem.
And your baby is not broken.
Babies Don’t “Fight Sleep”
This is one of the biggest misconceptions in the sleep world.
Babies are not wired to resist something they biologically need.
Sleep is not something they avoid or need to be taught.
it’s something their body allows when the conditions feel right.
If your baby isn’t falling asleep, it’s not defiance.
It’s communication. Independent sleep especially is not a milestone and is not the goal.
Sleep Happens When the Nervous System Feels Safe
Your baby’s sleep is not controlled by schedules or perfect timing.
It’s guided by their nervous system.
And your baby’s nervous system is deeply connected to yours.
Through something called mirror neurons, your baby is constantly sensing:
Your emotional state
Your stress level
Your pace
Your presence
So when things feel off, rushed, overstimulating, or disconnected…
Sleep can feel harder to access because their primal brain (the amygdala) is telling them something is wrong with their caregiver and it’s not safe to sleep yet.
Forget “Perfect Wake Windows”
You’ve probably seen charts telling you:
“Baby should sleep every 90 minutes”
“Watch for sleepy cues”
“Don’t miss the window”
Here’s the truth:
Sleepy cues are often misunderstood.
And wake windows are averages and not tailored to your baby’s unique sleep needs.
Yawning, rubbing eyes, fussiness?
Those don’t always mean “put baby down now.”
Sometimes they mean:
“I need a change of environment”
“I need connection”
“I need regulation”
I don’t even want you to move on without reflecting on this. 9/10 moms I work with in the early days are simply trying to get their baby’s to sleep too often. They do all the “right” things and then get stressed out that their baby is chronically overtired. I’ve been there-but trust the process. There is not good evidence for the concept of a baby being chronically overtired. More likely, they are stressed that you are trying to get them asleep again. This is where the next section is key:
The 5–10 Minute Reset Rule
If your baby isn’t falling asleep within 5-10 minutes…
Pause. Step away from trying. Reset.
Take your baby outside.
Go for a short walk
Step into fresh air
Change the sensory input
This helps regulate both of your nervous systems.
Then try again later when they seem ready.
Most of the time, sleep comes much easier after a reset.
Your Baby Needs Closeness (Not Independence Training)
Your baby isn’t meant to sleep alone early in life.
They are wired for:
Touch
Proximity
Movement
Connection
This isn’t a habit to break.
It’s biology.
Research from Greer Kirshenbaum shows that:
Close, responsive care helps build the developing brain
It supports emotional regulation
It leads to greater long-term resilience and mental health
So if your baby sleeps best:
On you
Next to you
While feeding or being held
That’s not a problem.
That’s development.
What Actually Helps Sleep (Long-Term)
Instead of focusing on “getting baby to sleep,”
focus on building a full, regulated day:
Outdoor time + natural light
Sensory experiences (movement, touch, play)
Emotional connection + responsiveness
Rhythms instead of rigid schedules
Sleep is a byproduct of these things.
When to Look Deeper
If your baby truly struggles to fall asleep consistently—even when you’ve:
Increased outdoor time
Prioritized connection and closeness
Tried resets and rhythm-based days
…it may be worth exploring deeper support.
One often overlooked piece:
Iron store levels (ferritin)
Low ferritin can impact ability to fall sleep and cause restlessness. I see this most often the case if mom’s ferritin or iron was low at any point in pregnancy & with preemie babies.
Talk with your healthcare provider about testing if needed.
Your baby isn’t fighting sleep.
They’re asking for:
Regulation
Connection
Support
And you are already responding even when it feels messy and even when it takes more time than expected. You are incredible.
A Simple Next Step
When your baby won’t sleep, it can be hard to think clearly in the moment.
I created a simple screensaver you can pull up anytime so you’re never stuck wondering what to do. Sometimes in the chaos we forget the obvious things, so this is a helpful checklist to run through!
You don’t need to train your baby to sleep.
You definitely don’t need to override your instincts.
You don’t need to do this perfectly. Sleep will come when baby is ready. Try to relax and enjoy the extra moments of play time.
And in the meantime you are building something far more important:
a connected, secure, and resilient human.
