Normal Noisy Breathing in Newborns
The short answer
Newborns are notoriously noisy breathers. Squeaking, whistling, snorting, rattling, and gurgling sounds are very common and usually normal because babies have small, flexible airways and narrow nasal passages. As long as your baby is breathing comfortably, feeding well, and has normal skin color, noisy breathing is rarely a cause for concern.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
Newborns make a wide variety of breathing sounds that can worry new parents. Snorting and snuffling occur because nasal passages are narrow. Squeaking may happen because the airway cartilage is still soft and flexible. Gurgling or rattling sounds can be caused by saliva or mucus in the back of the throat. Brief pauses in breathing (up to 10 seconds) are normal periodic breathing. These sounds are generally louder when baby is sleeping or lying on their back. As long as your baby's breathing rate is normal (30-60 breaths per minute), skin color is good, and feeding is going well, these sounds are typically benign.
Noisy breathing may continue or even seem louder as your baby grows and moves more air through their still-small airways. Some babies develop stridor (a high-pitched sound with breathing), which can be caused by laryngomalacia (floppy airway tissue), a common and usually self-resolving condition. If the noise is consistently present and gets worse during feeding or when your baby is on their back, mention it to your pediatrician.
Many breathing sounds improve as airways grow. Laryngomalacia, if present, often peaks around 4-8 months. Noisy breathing that improves with positioning (better on tummy) and does not affect feeding or growth is usually managed with observation. New or worsening respiratory noises should be evaluated.
Airways continue to grow and become firmer. Most normal noisy breathing has resolved or significantly improved by this age. Persistent stridor, wheezing, or noisy breathing should be evaluated by your pediatrician to rule out conditions that may need treatment.
What Should You Do?
When to take action
- Snorting, squeaking, or gurgling sounds during sleep that do not affect breathing rate or comfort
- Noisy breathing that comes and goes and is related to position or activity
- Baby has normal skin color, feeds well, and grows normally
- Breathing rate stays between 30-60 breaths per minute in the newborn period
- A consistent high-pitched sound (stridor) with every breath, especially during feeding
- Noisy breathing that seems to be getting louder or more persistent over time
- Baby seems to work harder to breathe during feeds or tires easily
- Any signs of breathing difficulty: nasal flaring, chest retractions (skin pulling in between ribs), belly breathing, or breathing faster than 60 breaths per minute
- Blue or gray color of the lips, tongue, or face, or episodes where breathing stops for more than 20 seconds

Normal Baby Breathing Patterns
Newborns and young babies have breathing patterns that can seem alarming to parents but are perfectly normal. Periodic breathing -- rapid breaths followed by brief pauses of up to 10 seconds -- is common, especially during sleep. Normal newborn breathing rates range from 30-60 breaths per minute and are naturally irregular. Babies are obligate nose breathers and may sound congested without being sick. True warning signs include persistent fast breathing, pauses longer than 20 seconds, chest retractions, grunting, or color changes.
Stridor (Noisy Breathing) in Babies
Stridor is a high-pitched, squeaky or whistling sound heard when a baby breathes in (and sometimes out). It is caused by narrowing or obstruction of the upper airway. The most common cause in infants is laryngomalacia (a floppy voice box), which is usually harmless and outgrown. However, stridor can also be caused by croup, vocal cord problems, airway malformations, or foreign body aspiration. New-onset stridor or stridor with breathing difficulty always needs medical evaluation.
Laryngomalacia (Floppy Airway)
Laryngomalacia is the most common cause of noisy breathing (stridor) in infants. It occurs when the tissue above the vocal cords is unusually soft and floppy, causing it to collapse inward during breathing and create a high-pitched squeaky sound. It typically appears within the first 2 weeks of life, peaks in severity at 4-8 months, and resolves on its own by 12-18 months. Most cases are mild and require no treatment beyond monitoring.
Nasal Congestion in Newborns Without a Cold
Nasal congestion in newborns without a cold is very common and usually harmless. Newborns have very small nasal passages that are easily congested by normal mucus, dried milk, lint, or dry air. Because babies breathe primarily through their noses, even mild congestion can sound significant. Saline drops and a bulb syringe or nasal aspirator can help, along with a cool-mist humidifier.
My Baby's Head Shape Looks Abnormal
Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.
Achondroplasia (Dwarfism) in Babies
Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
