Baby Wakes Every Hour at Night: Why It Happens & What Parents Can Do
Share
If your baby is waking every hour at night, it does not automatically mean something is wrong.
Young babies naturally move through relatively short sleep periods and may wake for feeding, comfort or during transitions between sleep cycles. Sleep patterns also change considerably during the first year.
But age matters. Frequent waking in a young newborn is very different from a sudden change in an older baby who previously slept for longer stretches.
If hourly waking is new, persistent or accompanied by poor feeding, poor weight gain, fever, breathing difficulty, significant vomiting, pain or other signs of illness, contact your pediatrician.
- Frequent waking can be normal in young infants.
- Newborns often sleep in short stretches rather than continuously through the night.
- Hunger is an important cause of waking, particularly in younger babies.
- Babies naturally wake or partially arouse as they move between sleep cycles.
- Developmental changes can temporarily disrupt previously established sleep patterns.
- Illness, discomfort, teething or environmental changes can also affect sleep.
- Look at your baby's total sleep over 24 hours, not nighttime sleep alone.
- Safe-sleep practices still apply after every nighttime awakening.
Why Does My Baby Wake Up Every Hour?
When you're getting out of bed for the fifth or sixth time in one night, hourly waking can feel as though something must be wrong.
Sometimes there is a problem worth investigating.
But often the explanation is normal infant sleep development.
Babies do not sleep exactly like adults. Their sleep organization changes dramatically during the first months of life, and they naturally move between different stages of sleep throughout the night.
Brief waking is therefore not unusual.
The more useful question is not simply, “Does my baby wake?”
It is:
Why is my baby waking, how old is my baby, and what happens when the baby wakes?
First, Consider Your Baby's Age
Age completely changes how we interpret nighttime waking.
Newborns
Newborn sleep is fragmented by design. Young babies need frequent feeding and do not yet have mature day-night sleep organization.
A newborn who wakes frequently to eat and then settles again may be behaving exactly as expected.
Trying to force a young newborn to sleep for long uninterrupted stretches can interfere with necessary feeding.
Older infants
As babies mature, many begin sleeping for longer stretches—but there is enormous individual variation.
Even babies who have begun sleeping for longer periods may still wake briefly during the night.
A baby who suddenly begins waking hourly after previously sleeping much longer stretches deserves a different look than a newborn who has always awakened frequently.
Reason #1: Your Baby May Be Hungry
Hunger is one of the first things to consider, particularly in younger infants.
Babies have small stomachs, grow rapidly and may need to feed frequently around the clock.
The number and timing of nighttime feeds depend on your baby's age, feeding method, growth, health and individual needs.
Some babies continue to require nighttime feeding after other babies of the same age have begun sleeping for longer stretches.
Rather than focusing only on how often your baby wakes, consider:
- How well your baby feeds during the day
- Whether feeding seems effective
- Wet diaper patterns
- Growth and weight gain
- Whether your baby seems satisfied after feeding
- Whether your pediatrician has recommended waking your baby for feeds
If you are uncertain whether your baby still needs nighttime feeds, discuss it with your pediatrician rather than simply eliminating them.
Reason #2: Your Baby Is Moving Between Sleep Cycles
Babies naturally move through repeating sleep cycles.
At transitions between cycles, a baby may move, make noises, briefly open the eyes or wake more completely.
Some babies move into the next sleep period with very little help.
Others signal for a caregiver.
This is one reason a baby can appear to wake at remarkably predictable intervals during the night.
Waking itself is not necessarily the problem. The question is whether your baby is comfortable, growing appropriately and gradually developing the ability to return to sleep.
Reason #3: Your Baby May Need the Same Help Used at Bedtime
Babies learn patterns very quickly.
If your baby consistently falls asleep while feeding, rocking, bouncing or being held, the baby may look for that same familiar condition after waking between sleep periods.
This does not mean you have done something wrong.
Feeding, rocking and holding are normal ways to comfort babies.
But in an older infant, repeated dependence on one specific condition for falling asleep can sometimes contribute to frequent signaling for a caregiver overnight.
If that pattern is exhausting your family, you can gradually work on additional ways of settling your baby that are appropriate for the baby's age and temperament.
Reason #4: Your Baby's Sleep Is Changing Developmentally
Infant sleep does not develop in a straight line.
A baby may sleep longer stretches for several weeks and then suddenly begin waking more frequently.
Changes in sleep organization, increased awareness of the environment, new motor abilities and other developmental changes can all affect nighttime sleep.
This is why parents often describe periods of worsening sleep as a “sleep regression.”
The pattern can be frustrating, but a temporary change does not mean your baby's sleep has been permanently disrupted.
Reason #5: Your Baby May Be Uncomfortable
A baby who suddenly begins waking much more frequently may be uncomfortable.
Possible reasons include:
- Nasal congestion
- Cough
- Fever or illness
- Ear discomfort
- Teething discomfort
- Skin irritation or eczema
- Being too hot or too cold
- A wet or soiled diaper
- Gastrointestinal discomfort
The key clue is often a change from your baby's usual pattern.
If a baby who normally sleeps several hours at a time suddenly begins waking every hour and seems uncomfortable, look beyond sleep habits.
Reason #6: Your Baby May Be Overtired
It seems logical that keeping a baby awake longer would produce better nighttime sleep.
It often does not.
A baby who becomes excessively tired may be fussier, harder to settle and more difficult to resettle after waking.
Age-appropriate daytime sleep and reasonably consistent sleep opportunities may help prevent the cycle of an exhausted baby becoming increasingly difficult to settle.
Do not eliminate needed naps simply in hopes of forcing longer nighttime sleep.
How Much Sleep Should My Baby Be Getting?
Total sleep matters more than nighttime sleep alone.
For healthy infants 4 through 12 months old, the American Academy of Sleep Medicine recommends approximately 12 to 16 hours of sleep per 24 hours, including naps.
There is no single evidence-based sleep-duration recommendation for babies younger than 4 months because normal sleep variation is especially wide during early infancy.
Individual babies also differ in their sleep needs.
A baby can therefore wake several times overnight and still accumulate an appropriate amount of total sleep over 24 hours.
What Can Parents Do About Hourly Waking?
- Make sure your baby's feeding needs are being met.
- Keep nighttime interactions calm and relatively quiet.
- Keep lights low during nighttime care.
- Use a simple, predictable bedtime routine.
- Provide age-appropriate opportunities for daytime sleep.
- Look for signs of illness or discomfort if the waking pattern suddenly changes.
- Give an older baby a brief opportunity to resettle when appropriate before assuming every sound requires immediate intervention.
- Discuss persistent or concerning waking with your pediatrician.
There is no single technique that makes every baby stop waking.
Start by figuring out why your baby is waking rather than trying random sleep strategies.
Do I Need to Respond Every Time My Baby Makes a Noise?
Not necessarily.
Infants can be surprisingly noisy sleepers.
They may grunt, wiggle, briefly cry out or open their eyes without being fully awake.
If your baby is in a safe sleep environment and does not appear distressed, you can sometimes pause briefly and observe before intervening.
You may discover that your baby returns to sleep without help.
This is different from ignoring a young baby's clear hunger cues, significant crying or signs of illness.
Don't Sacrifice Safe Sleep Because You're Exhausted
This deserves special attention because hourly waking can leave parents profoundly tired.
After every nighttime waking, your infant should return to a safe sleep environment.
For the first year, the American Academy of Pediatrics recommends placing babies on their backs on a firm, flat, noninclined sleep surface designed for infant sleep, without loose blankets, pillows, stuffed animals or other soft objects.
Do not fall asleep holding your baby on a couch or armchair.
If you bring your baby into your bed for feeding or comforting, return the baby to the separate infant sleep space when you are ready to sleep.
Never use pillows, positioners, nests, loose blankets or inclined products in an attempt to make your baby sleep longer.
Research has found that families sometimes use less-safe sleep practices after nighttime awakenings than they used when initially putting the baby to bed.
The safe-sleep rules still matter at 3 a.m.
When Does Hourly Waking Become Concerning?
The frequency of waking alone does not tell us whether something is medically wrong.
We look at the entire baby.
Contact your pediatrician if frequent waking is associated with:
- Poor feeding
- Poor weight gain or concerns about growth
- Fewer wet diapers than expected
- Persistent vomiting
- Significant reflux symptoms or apparent pain
- Fever or other signs of illness
- Persistent cough or congestion interfering with feeding or sleep
- Repeated loud snoring or concerning noisy breathing
- Pauses in breathing
- Unusual difficulty waking your baby
- A major sudden change from your baby's normal sleep pattern
- Night waking that is becoming unmanageable for your family
Your pediatrician can help determine whether the waking is developmentally typical or whether feeding, growth, breathing, illness or another issue needs attention.
When Is It an Emergency?
Seek emergency medical attention if your baby:
- Has severe difficulty breathing
- Turns blue, gray or unusually pale
- Has a prolonged pause in breathing
- Becomes limp or unresponsive
- Cannot be awakened normally
- Has another symptom that appears immediately life-threatening
If your baby is unresponsive or not breathing normally, call emergency services immediately.
Frequently Asked Questions
Is it normal for a newborn to wake every hour?
It can be. Newborn sleep is naturally fragmented, and young babies wake frequently for feeding and comfort. What matters is whether your baby feeds well, has appropriate wet diapers, grows appropriately and otherwise appears healthy.
Why is my baby suddenly waking every hour?
A sudden change can occur with developmental changes, hunger, changes in daytime sleep, discomfort, teething or illness. If the change is significant or your baby appears unwell, contact your pediatrician.
Why does my baby wake every 45 to 60 minutes?
That timing may coincide with transitions in sleep. Some babies briefly arouse during those transitions and then return to sleep, while others become fully awake and signal for a caregiver.
Should I feed my baby every time they wake?
That depends on your baby's age, feeding pattern, growth and health. Young infants may legitimately need frequent nighttime feeds. If you are unsure whether your older baby still needs feeding at each awakening, discuss it with your pediatrician.
Should I keep my baby awake more during the day?
Do not intentionally deprive your baby of needed daytime sleep in hopes of producing better nighttime sleep. An overtired baby may actually become more difficult to settle.
Does waking frequently mean my baby isn't getting enough sleep?
Not necessarily. Total sleep across the entire 24-hour day is important. Infants may obtain substantial sleep through a combination of nighttime sleep and daytime naps.
Will my baby eventually stop waking so often?
Most babies gradually develop longer and more consolidated periods of sleep as they mature, although the timing varies considerably from child to child and temporary setbacks are common.
Can I put my baby on the stomach if they sleep longer that way?
No. Place your baby on the back to begin every sleep throughout the first year. Do not change to stomach positioning in an attempt to reduce nighttime waking.
Dr. G's Pearl
When a parent tells me, “My baby wakes every hour,” my first question isn't, “How do we make the baby sleep?” It's “Why is the baby waking?”
A hungry 6-week-old, a healthy 6-month-old moving between sleep cycles and an older baby who suddenly wakes because of an ear infection can all look like “bad sleep” at 2 a.m.—but they are very different situations.
Look at your baby's age, feeding, growth, daytime sleep, comfort and overall health. Once you understand the likely reason for the waking, the next step becomes much clearer.
