You finally get your newborn to sleep. You don't close your eyes, but instead find yourself watching their little chest rise and fall.
Is your baby breathing too fast? Is that tiny grunt normal?
This is how you've spent many nights counting your baby's breaths in the middle of the night. Newborns can have surprisingly irregular and noisy sleep. These kinds of sleep patterns are part of normal newborn development. Still, knowing what to look for can make it easier to tell the difference between normal sleep behavior and signs that need medical attention.
Is Fast Breathing Normal for Newborns?
Newborns naturally breathe faster than older children and adults. A typical newborn respiratory rate is around 40 to 60 breaths per minute, although breathing does not always happen at a perfectly steady pace.
You may notice your baby's breathing:
- Speed up for a short time
- Slow down again
- Become deeper or shallower
- Pause briefly and then restart
- Sound louder during certain parts of sleep
This can look strange when you're seeing it for the first time.
What Does Normal Newborn Breathing Look Like?
Newborns are still developing their breathing patterns. During sleep, especially active sleep, their breathing can become more irregular. You may also notice small movements, facial expressions, or little noises.
During active sleep, babies can have brief pauses in breathing followed by a short burst of faster breathing. This is known as periodic breathing and is generally considered normal when the baby remains comfortable and their color does not change.
That said, fast breathing should not automatically be assumed to be normal. If your baby consistently seems to be working hard to breathe, it's time to check with their pediatrician.
Why Do Newborns Breathe So Fast?
Part of the reason is simply that newborns have developing respiratory systems and naturally breathe faster than adults.
Their breathing can also change depending on what they are doing. Feeding, crying, nasal congestion, and different stages of sleep can all affect how their breathing looks and sounds.
The important thing is to look at the whole picture, rather than focusing on the number of breaths alone.
Why Is My Newborn Breathing Fast While Sleeping?
If you notice your newborn suddenly breathing faster while asleep, it can be especially unsettling. You may even find yourself leaning over the crib to take a closer look.
There are several possible explanations.
Active Sleep
Newborns spend a noteworthy amount of time in active sleep, a stage similar to REM sleep. During this stage, breathing can become irregular.
Your baby may move their arms or legs, make little facial expressions (that are definitely cute!), or suddenly breathe faster for a short period. These changes can be completely normal—especially when you’re watching them sleep and noticing every tiny little movement.
Periodic Breathing
Periodic breathing is another common newborn pattern.
A baby may briefly pause their breathing, then take several faster breaths before returning to their usual rhythm. The pauses are generally short, often around 5 to 10 seconds.
It can be startling to watch. For parents who like an extra way to stay connected during naps and bedtime, Sense-U Pro tracks your baby's abdominal movement through the app, so you can check in without repeatedly walking into the nursery.
If your baby remains comfortable, their skin color stays normal, and they are not showing signs of breathing difficulty, periodic breathing is usually not a cause for concern. Still, talk with your pediatrician if you are unsure about what you are seeing.
Other Things That Can Affect Breathing
Sometimes faster or noisier breathing may happen around:
- A stuffy nose
- Feeding
- Crying or fussiness
- Changes between sleep stages
- A warm or uncomfortable sleep environment
A congested nose can be particularly noticeable in newborns because their nasal passages are small. Nasal noises do not always mean your baby is sick.
Why Does My Newborn Make So Many Noises While Sleeping?
Newborns are not always quiet sleepers. If yours is, you've officially hit the quiet-sleep lottery!
You might hear grunts, snorts, squeaks, sighs, or even little cries. Some babies seem to make enough noise to convince their parents they are awake when they are actually still sleeping.
Grunting
An occasional grunt does not necessarily mean something is wrong. However, repeated grunting with every breath, especially when accompanied by other signs of breathing difficulty, should be checked by a medical professional.
Snorting
Newborns often make nasal sounds because of mucus or naturally narrow nasal passages.
So if you've been wondering, "Why is my newborn snorting?", a little snorting by itself does not necessarily mean your baby is having trouble breathing.
Squeaky Breathing
A high-pitched or squeaky sound when breathing can sometimes be a type of noisy breathing called stridor. In babies, one possible cause is laryngomalacia, which is often mild but should be evaluated when persistent or accompanied by feeding or breathing difficulties.
Sneezing
Yes, babies can sneeze while sleeping. Newborns may sneeze because they are clearing their small nasal passages. An occasional sneeze does not necessarily mean they have a cold.
Whimpering or Crying
Little whimpers, sighs, and cries can also happen during sleep. Newborn sleep can be surprisingly active.
If your baby is making lots of noises but otherwise looks comfortable, has normal color, and is breathing easily, the sounds themselves may not be a sign of a problem.
Remember: The sound alone isn't always the most important clue. Pay attention to your baby's breathing effort, color, and overall behavior.
How Can I Tell If My Newborn Is Having Trouble Breathing?
This is where it helps to look beyond how fast your baby is breathing.
A baby who is breathing quickly but comfortably can look very different from a baby who is struggling to breathe.
Signs That May Need Medical Attention
Contact your pediatrician promptly if you notice signs such as:
- Breathing that stays much faster than normal
- Skin pulling in around the ribs, chest, or neck with each breath
- Nostrils flaring
- Repeated grunting with breathing
- Unusual or prolonged pauses in breathing
- Blue or gray lips, face, or skin
- Difficulty feeding because of breathing
- Being unusually difficult to wake or appearing very unwell
These signs can indicate that your baby is working harder than usual to breathe.
The key takeaway is simple:
Breathing effort and your baby's overall appearance matter, too.
If something about your baby's breathing doesn't look right to you, trust your instincts and contact your pediatrician.
Fast Breathing or Trapped Gas? How Can I Tell the Difference?
Newborns can grunt and squirm for many reasons, especially around feeding. Sometimes it's hard to tell whether you're hearing a digestive noise or something related to breathing.
| What you notice | May be related to gas | May be more concerning for breathing |
|---|---|---|
| Grunting mainly after feeding | ✓ | |
| Pulling legs toward the belly | ✓ | |
| Burping or passing gas | ✓ | |
| Chest pulling in with breaths | ✓ | |
| Nostrils flaring | ✓ | |
| Blue or gray lips or skin | ✓ | |
| Persistent rapid breathing | ✓ |
This table is only a general guide, not a way to diagnose your baby.
If you're unsure whether your baby is struggling to breathe, it's safer to contact your pediatrician rather than assuming it's gas.
How to Check If Your Baby Is Breathing During Sleep
When your newborn is sleeping peacefully, it can be tempting to keep checking.
You may watch their chest. Then their belly. Then their face. And somehow you're still not convinced.
Look at Your Baby's Chest or Belly
One simple way to observe your baby's breathing is to watch for gentle movement of the chest or abdomen.
Newborn breathing may be subtle, so give yourself a moment to watch rather than judging it from one quick glance.
Listen and Watch
You can also pay attention to:
- The rhythm of breathing
- Chest or abdominal movement
- Unusual breathing sounds
- Skin and lip color
- Your baby's overall appearance
You don't need to interpret every tiny sound or movement.
Don't Rely on a Single Sign
A quiet baby isn't necessarily a baby who isn't breathing. Likewise, a noisy sleeper isn't necessarily a baby who is having breathing trouble.
Look at the overall pattern.
If your baby appears comfortable, has normal color, and is breathing without obvious effort, that's more reassuring than focusing on one isolated sound or movement.
When Should I Call the Doctor About My Newborn's Breathing?
When you're unsure, it's always okay to ask.
Contact Your Pediatrician If:
Your newborn's breathing seems consistently faster than normal, becomes increasingly noisy, or you notice changes in feeding, alertness, or overall behavior.
For newborns, a respiratory rate consistently above 60 breaths per minute can be a reason to contact your pediatrician, particularly when other symptoms are present.
Seek Urgent Medical Attention If:
Your baby is struggling with each breath, has significant chest retractions, develops blue or gray lips or skin, becomes very difficult to wake, or appears seriously unwell.
When in doubt, don't try to diagnose the cause yourself. Your pediatrician can assess your baby and help you understand what you're seeing.
How Can a Baby Monitor Help During Sleep?
A baby monitor can give you another way to stay connected during naps and bedtime without constantly walking into the nursery.
Depending on the type of monitor you choose, it may help you:
- Keep an eye on your baby during naps
- Check the sleep environment
- Observe your baby's movement
- Stay connected while your baby sleeps
For parents who want to keep an eye on their baby's sleep from a little farther away, Sense-U provides sleep-related data through its app, including your baby's abdominal movement and other available measurements.
A baby monitor is a helpful parenting tool, but it is not a substitute for medical care. If your baby is showing signs of breathing difficulty, contact a healthcare professional rather than relying on a monitor.
Frequently Asked Questions
Is it normal for newborns to breathe fast while sleeping?
It can be. Newborns naturally breathe faster than older children, and their breathing can become irregular during active sleep. Brief periods of faster breathing can also occur as part of periodic breathing.
However, persistent rapid breathing or breathing that looks difficult should be discussed with your pediatrician.
How fast should a newborn breathe?
A typical newborn breathing rate is around 40 to 60 breaths per minute. Because newborn breathing can be irregular, it's best to observe the pattern over a period of time rather than relying on a single breath count.
Why does my newborn make squeaky noises?
Squeaky or high-pitched breathing can have different causes. Persistent high-pitched breathing may be stridor and should be evaluated by a pediatrician, particularly if your baby also has feeding difficulties, pauses in breathing, or visible effort when breathing.
Why does my newborn whimper in their sleep?
Newborn sleep can be surprisingly active. Small cries, whimpers, grunts, and other sounds can happen while babies move between sleep stages. If your baby otherwise appears comfortable and healthy, occasional sleep noises are often not a reason for concern.
A Final Note for New Parents
Newborns can make sleep look more complicated than it is. Their breathing changes, they make funny little noises, and sometimes they suddenly breathe faster before settling down.
It can be scary when you're exhausted and watching every tiny movement. That's why learning your baby's normal patterns, recognizing signs of breathing difficulty, and knowing when to ask for help matters.
