newborn-careNewborn Breathing Patterns: What Is Normal and When to Seek Help
Normal newborn breathing rates, periodic breathing explained, the sounds that are harmless, and the specific warning signs that need same-day or emergency assessment.
Newborn Breathing Patterns: What Is Normal and When to Seek Help
Watching a newborn breathe can be simultaneously mesmerising and terrifying. Their chest rises in quick, shallow bursts; they pause for a few seconds and then breathe again; they grunt, snuffle, and occasionally make a sound that stops your heart for a second. Understanding what is genuinely normal — and what requires a phone call or an emergency visit — is one of the most useful things a new parent can know.
This article covers normal newborn respiratory rates, the phenomenon of periodic breathing, the sounds that are harmless, the behaviours parents frequently mistake for breathing problems, and the specific warning signs that warrant urgent medical assessment.

How Fast Should a Newborn Breathe?
Newborns breathe significantly faster than older children or adults. The normal respiratory rate for a newborn is 40 to 60 breaths per minute. To put that in perspective, a resting adult breathes roughly 12 to 20 times per minute. The NHS confirms that a rate of 40 to 60 breaths per minute is expected in a healthy newborn.
The rate is not constant. After crying, feeding, or any physical effort, a newborn's breathing will speed up temporarily. This is normal. A rate that consistently exceeds 60 breaths per minute while the baby is calm and at rest is the threshold at which healthcare professionals want to investigate further.
If you want to count your baby's breaths, do it while they are calm and undisturbed. Watch the rise and fall of the chest or belly and count for a full 60 seconds. Counting for only 15 seconds and multiplying by four is less accurate with newborns because their breathing is naturally irregular.
Periodic Breathing: What It Is and Why It Is Not Apnoea
One of the most alarming-looking things a newborn does is pause between breaths. These pauses can last up to 10 seconds and are entirely normal in the newborn period. This pattern — breathing rapidly for a stretch, then pausing briefly, then breathing rapidly again — is called periodic breathing.
Periodic breathing is the result of an immature brainstem. The part of the brain that regulates breathing is still developing in the weeks after birth, and this irregular rhythm reflects that immaturity rather than anything dangerous. According to the American Academy of Pediatrics (AAP), periodic breathing in healthy term newborns resolves on its own as the nervous system matures.
Periodic breathing should not be confused with apnoea. True apnoea is a pause lasting longer than 20 seconds, or a shorter pause accompanied by a change in skin colour (going pale, blue, or grey) or a significant drop in muscle tone. Periodic breathing does not cause any of these changes. The baby looks perfectly comfortable throughout.
Premature babies are more prone to apnoea of prematurity, which is a distinct clinical condition monitored carefully in neonatal units. If your baby was born early, their medical team will have already addressed this with you directly.
The Sounds of Normal Newborn Breathing
New parents are frequently surprised by how noisy a newborn's breathing can be. The nasal passages are tiny, and any secretion, milk residue, or normal mucus narrows the airway enough to create sounds. Here is what is normal:
Snuffling and Snorting
Newborns are obligate nasal breathers for the first few months of life. This means they breathe primarily through their noses rather than their mouths. Any congestion — even a small amount of mucus — creates a snuffling, snorting, or slightly raspy sound. This is extremely common and does not indicate illness. Saline nasal drops (available over the counter and recommended by the NHS for newborns with congestion) can help keep the nasal passages clear.
Grunting During Straining
Many newborns grunt during bowel movements or when pushing against a full nappy. This grunt is caused by the baby using their diaphragm to create abdominal pressure. It is entirely normal and not a sign of respiratory distress. The distinction to know is that this grunting is linked to straining and stops once the effort is over.
Occasional Noisy or Rattly Breathing
Milk can pool at the back of the throat during and after feeds, causing a rattly or gurgling sound. Keeping the baby upright for 20 to 30 minutes after feeds and ensuring a good latch helps reduce this. If the rattly sound is present all the time regardless of feeding, speak to your health visitor or GP to rule out laryngomalacia, a common and usually self-resolving softness of the laryngeal cartilage.
Sneezing
Newborns sneeze frequently, not because they are unwell, but because sneezing is the primary way they clear their nasal passages. A sneezing newborn without fever, colour change, or other symptoms is not unwell.
What Parents Often Mistake for Breathing Problems
The Startle Reflex
Newborns have a primitive startle response (Moro reflex) that causes them to suddenly extend their arms, gasp, and then pull their limbs back in. This can look like a sudden breathing disturbance but is a normal neurological reflex that disappears by around four months. It tends to occur in response to sudden sounds or movement.
Irregular Sleep Breathing
Breathing during active sleep (the newborn equivalent of REM sleep) is faster and more irregular than during quiet sleep. Parents watching a sleeping baby may see the breathing slow, quicken, or pause briefly. As long as the baby's colour remains pink and they continue breathing within the 20-second window, this is normal sleep physiology.
Hiccups
Newborn hiccups are very common and caused by diaphragm spasms. They do not cause distress or breathing problems and resolve on their own.
Warning Signs That Require Urgent Assessment
The following signs are not normal and should prompt an immediate call to your GP, NHS 111, or emergency services. If you are in doubt, always err on the side of seeking help. The NHS and AAP both recommend that parents trust their instincts when something does not feel right.
Sustained Respiratory Rate Over 60 Breaths Per Minute
A persistent rate of more than 60 breaths per minute while the baby is calm is called tachypnoea. This needs same-day clinical assessment to determine the cause.
Retractions
Retractions occur when the muscles between the ribs, above the collarbone, or at the base of the throat are visibly pulled inward with each breath. This means the baby is working hard to breathe and is a significant warning sign. If you can see the skin being sucked in between the ribs or at the neck with every breath, seek urgent medical attention.
Nasal Flaring
Flaring of the nostrils on every breath indicates increased respiratory effort. Like retractions, nasal flaring signals that the baby is working harder than normal to move air and needs to be assessed promptly.
Grunting on Every Breath
Grunting during straining for a nappy is normal. Grunting on every single breath — at rest, not during effort — is different. It is the body's way of maintaining pressure in the lungs to keep the small airways open, and it is a sign of respiratory distress.
Cyanosis
Blue or grey colouration around the lips, inside the mouth, or at the fingertips is called cyanosis. It indicates that oxygen levels in the blood are low. This is always an emergency. Call 999 immediately. Note that it is normal for a newborn's hands and feet to look slightly blue or mottled when they are cold (acrocyanosis). The concerning colour change is around the lips and tongue, not the extremities.
Apnoea Lasting More Than 20 Seconds, or Shorter Pauses With Colour Change
A breathing pause lasting more than 20 seconds, or any pause accompanied by the baby going pale, blue, limp, or unresponsive, is a medical emergency. Call 999.
RSV and Bronchiolitis
Respiratory syncytial virus (RSV) is the most common cause of bronchiolitis, a lower respiratory tract infection that is the leading cause of breathing difficulty in babies under 12 months in the UK. The NHS reports that most babies with bronchiolitis develop only a mild cold-like illness, but around 2 to 3 percent require hospital admission.
Signs of bronchiolitis include a runny nose progressing to a worsening cough, rapid breathing, difficulty feeding, and a characteristic wheeze or crackle when breathing. Bronchiolitis peaks between November and March. There is no antibiotic treatment for viral bronchiolitis, but supportive care is important. Seek same-day medical assessment for any baby under 3 months with breathing changes, and emergency assessment for retractions, persistent oxygen needs, or feeding difficulty.
In 2023, the UK introduced a maternal RSV vaccine offered to pregnant women between 28 and 36 weeks of pregnancy to pass protective antibodies to the baby before birth. Discuss this with your midwife or GP.
Safe Sleep Positioning and Breathing
The relationship between sleep position and breathing is important. The NHS, the AAP, and the WHO all recommend that babies sleep on their backs on a firm, flat surface for every sleep, including naps. This is called the back-to-sleep recommendation and is the single most effective intervention for reducing the risk of sudden infant death syndrome (SIDS).
Placing a baby on their stomach to sleep significantly increases the risk of SIDS. The mechanisms are not fully understood, but evidence consistently shows that tummy sleeping is associated with higher rates of SIDS, likely because it can cause rebreathing of exhaled air and interferes with the baby's ability to rouse from sleep when oxygen levels drop.
Some parents worry that a baby will choke if sick while sleeping on their back. The NHS reassures parents that healthy babies are very unlikely to choke in the back-to-sleep position because of the anatomy of the infant airway. The oesophagus sits behind the trachea, and gag and swallowing reflexes help clear any fluid.
Supervised tummy time when the baby is awake is beneficial for developing neck and shoulder strength and should start from birth in short periods under close supervision.
When to Call for Help
For general guidance: NHS 111 is available 24 hours a day. If your baby is showing any of the warning signs listed above, do not wait for a regular appointment. Same-day assessment is appropriate for a sustained rate over 60, persistent nasal flaring, or any sign of increased work of breathing. Call 999 for cyanosis, apnoea with colour change, or a baby who is limp or unresponsive.
Always speak to a GP or paediatrician if you have ongoing concerns about your baby's breathing, even if no emergency signs are present. Parental concern is a valid clinical reason to seek a review.
Frequently Asked Questions
What is the normal breathing rate for a newborn?
The normal range is 40 to 60 breaths per minute. This is much faster than adult breathing, which is 12 to 20 breaths per minute. A newborn's rate will temporarily increase after crying or feeding, which is normal.
What is periodic breathing and is it dangerous?
Periodic breathing is a pattern of brief pauses of up to 10 seconds between breaths that is entirely normal in newborns. It reflects the immaturity of the brainstem's breathing regulation centre. It is not apnoea and does not cause colour change or limpness. It resolves naturally as the baby matures.
My newborn grunts a lot. Is that normal?
Grunting during bowel movements or straining is normal. What is not normal is grunting on every breath while at rest — that can indicate respiratory distress and warrants same-day medical assessment.
What does cyanosis look like and what should I do?
Cyanosis is a blue or greyish colour around the lips, inside the mouth, or at the fingertips (not just the hands and feet, which can look mottled in the cold). It indicates low blood oxygen and is a medical emergency. Call 999.
How can I reduce my baby's risk of RSV and bronchiolitis?
Keep newborns away from people with colds where possible, especially during the RSV season (November to March). Breastfeeding provides some immune protection. Ask your midwife or GP about the maternal RSV vaccine available during pregnancy, which passes antibodies to the baby before birth.
My baby sneezes constantly. Does that mean they are ill?
Not necessarily. Newborns sneeze very frequently as their primary mechanism for clearing nasal passages. Sneezing without other symptoms such as fever, colour change, or feeding difficulty is normal newborn behaviour.
Key Takeaways
- A normal newborn breathes 40 to 60 times per minute — much faster than adults; a brief increase after crying or feeding is normal.
- Periodic breathing (pauses of up to 10 seconds) is normal and reflects an immature brainstem; true apnoea lasts more than 20 seconds or accompanies a colour change.
- Snuffling, grunting during straining, occasional rattling from milk, and frequent sneezing are all harmless sounds in healthy newborns.
- Warning signs requiring urgent assessment include: a sustained rate over 60 at rest, retractions, nasal flaring, grunting on every breath, and cyanosis around the lips.
- Cyanosis (blue colouring around the mouth and tongue) and apnoea with colour change or limpness are emergencies — call 999.
- The back-to-sleep position on a firm, flat surface for every sleep is the most effective way to reduce SIDS risk, as recommended by the NHS, AAP, and WHO.
