If you landed here at 3 a.m. with a baby on your chest and a half eaten granola bar in your hair, welcome. A 6 month old waking hourly can make even the most patient parent start negotiating with the universe. Whether your baby was sleeping great and suddenly fell apart or has never slept longer than a Netflix intro, this age is peak chaos for sleep.
But here is the good news.
This is extremely common.
This is fixable.
And this does not mean anything is wrong with your baby or your parenting.
Below is your full guide to why a six month old not sleeping through the night can happen, why your baby might be waking up every hour or every 2 hours, how younger babies fit into this pattern, and what you can actually do about it. Frequent night waking at six months is usually linked to sleep associations or growth spurts. Reviewing age-appropriate guidance from the sleep hub can help pinpoint the cause.
Understanding Why Your Baby Wakes Hourly at This Age
Six months is a big developmental moment. Skills, hunger, teething, and brain leaps all collide. That is why parents all across the internet are Googling things like why is my 6 month old waking up every hour, why is my 6 month old waking up at night, and why is my 6 month old waking every two hours.
Sometimes hourly wakeups are temporary. Sometimes they are part of a phase. And sometimes they simply reflect normal baby development that nobody prepared you for.
Let’s break it down by age so you understand the whole picture.
Newborn Waking Patterns: The Start of Hourly Chaos
If your newborn wakes up every hour or your newborn waking every hour seems never ending, this is normal biology. Newborn stomachs are tiny. Their sleep cycles are short. They rely heavily on contact for regulation.
A newborn waking every 2 hours is textbook newborn behavior. If you ever think why does my newborn wake up every hour or why is my newborn waking up every hour, please know that nothing unusual is happening.
This foundation is important because many older baby sleep issues stem from patterns that began in the first weeks.
Three Month Old Waking Every Hour: A Mini Regression
Right around three months, things shift again.
A 3 month old waking up every hour, or a 3 month old waking every 2 hours, is usually linked to:
- more alertness
- shorter naps
- hunger changes
- developmental leaps
Babies this age often sleep lighter and start noticing the world, which can disrupt formerly predictable stretches.
Five Month Old Sleep: The Pre-Regression Warm-Up
Five months is the warm up act before the major regression.
If your five month old waking up every hour feels surprising or your 5 month old waking up every 2 hours started suddenly, common causes include:
- teething pressure
- distractible daytime feeding
- growth spurts
- rolling and physical changes
A baby waking up every hour at five months is often gearing up for the bigger six month sleep shift.
Why Your 6 Month Old Is Waking Hourly
Now we are at the main event: the reason you clicked this post.
If your 6 month old waking every hour or your 6 month old waking every 2 hours or your 6 month old waking multiple times in night has become the new normal, you are likely encountering a perfect storm of:
1. Teething discomfort
Nothing disrupts sleep like gums that feel like tiny jackhammers.
2. Increased hunger
Six month olds often need more daytime calories. Undereating by day = waking by night.
3. New mobility
Rolling, scooting, rocking. Babies love to practice skills at ridiculous hours.
4. Separation awareness
They suddenly notice when you are gone and want reassurance.
5. Nap transitions
This age often shifts from 4 naps to 3, which can temporarily cause overnight chaos.
6. Classic sleep regression at 6 months old
This one hits hard. Even a previously great sleeper can experience breakdowns.
If you have asked why is my 6 month old not sleeping or six month old not sleeping through the night or 6 month old not sleeping through the night, this is usually why. It is not a red flag. It is a developmental leap.
If your 6 month old waking up at night is the new pattern, the good news is that this regression is temporary.
Why Babies of All Ages Wake Every Hour: Universal Factors
Even beyond the six month regression, parents often ask why is my baby waking up every hour or why does my baby wake up every hour. Here are the common universal reasons:
Hunger
Nighttime calories sometimes increase during rapid development.
Discomfort
Teething, gas, temperature shifts, and growth pains all impact sleep.
Over-tiredness
Too much wake time can lead to fragmented sleep due to spikes in cortisol throughout the night.
Under-tiredness
Babies who are not sleepy enough also wake more frequently.
Developmental leaps
From newborn to six months, skill development can wreak havoc on sleep cycles.
Habit waking
Some babies wake out of routine, not need, but this is fixable.
What To Do When Your Baby Wakes Every Hour
1. Create a predictable bedtime rhythm
A simple flow every night helps babies anticipate sleep.
2. Increase daytime calories
This reduces hunger driven waking and supports growth spurts.
3. Optimize the sleep setup
Dark room
Cool temperature
White noise
Safe sleep space

4. Shorten wake windows
Overtired babies wake more often.
5. Offer comfort during teething
Cold teether
Gentle gum massage
Pediatric approved medication when appropriate
6. Support new skills during the day
Practice rolling, sitting, and scooting plenty during wake times. If your baby is working on new skills, this post explains how sensory play helps regulate their nervous system.
When To Talk To Your Pediatrician
If your infant wakes up every hour and seems uncomfortable, is not feeding well, has breathing concerns, or wakes crying in pain, it is always worth checking in with your doctor. Most frequent waking is normal, but your instincts matter.
You Are Not Doing Anything Wrong
A baby waking every 2 hours, or every hour, can break even the strongest parent. It is exhausting; It is relentless. And while it can feel personal, remember that it isn’t.
Whether it is your newborn, your three month old, your five month old, or your 6 month old waking hourly, this phase does not define your child’s future sleep.
One day, they will surprise you and sleep longer – you will wake up and realize you slept through the night and this will be a distant blur.
You are doing a great job.
Your baby is doing exactly what babies do.
You will get through this. Soon you 6 month old waking hourly will be a distant memory.
