Newborns are noisy sleepers due to a variety of developmental and physical factors. They have different sleep patterns from adults, spending more time in REM sleep, which is associated with dreaming and periodic breathing. Their immature digestive systems, smaller lungs, and narrower airways also contribute to the noises they make. While most sleep sounds are normal and expected, some may indicate a health concern, such as respiratory distress or asthma. It is always recommended to consult a medical professional if there are any breathing concerns or questions about a baby's sleep noises.

What You'll Learn
Babies have short sleep cycles
Newborns and infants are notoriously noisy sleepers, and it can be surprising how much noise they make while sleeping peacefully. In fact, it would be strange if they didn't make noise while sleeping. This is because babies have short sleep cycles, constantly drifting in and out of sleep.
Newborn babies typically sleep around 16 hours a day, but this can vary from baby to baby. During these short sleep cycles, babies move between quiet sleep and active sleep. While in active sleep, babies make noise, move around, and sometimes even open their eyes, all while they're actually asleep. They may make grunting noises, moan, whimper, sigh, and even cry out.
The short sleep cycles of newborns are due to their higher percentage of REM sleep, which is a lighter sleep state associated with dreaming. Their brains are full of dream activity, and this can lead to noisier sleep. Newborns also experience periodic breathing, where they may stop breathing for a few seconds before restarting with fast breaths. This can be alarming for parents, but it is a normal part of their sleep cycle.
As babies mature, their sleep cycles lengthen, and they spend more time in deep sleep. By the time a baby is between three and six months old, they will be spending more time in deep sleep versus active REM sleep. Their sleep will become less disrupted, and the growing pains of their lungs will have resolved.
While most baby sleep noises are normal, there are some instances where you should seek medical advice. If your baby is struggling to breathe, looks blue, or has a fever, contact your doctor or an emergency number. Noisy breathing should always be checked by a doctor to ensure there is no underlying medical cause.

They spend more time in REM sleep
Newborns go through two different sleep cycles: quiet sleep and active sleep. They spend about half of their sleeping time in each cycle. Active sleep is similar to REM sleep for adults, but with one key difference. During the REM stage, adults experience skeletal muscle paralysis, but newborn babies do not. Instead, babies move around, make noise (including grunting and crying), and sometimes even open their eyes, all while they're actually sleeping.
During the REM stage of sleep, babies experience periodic breathing, so it's common for them to stop breathing for a few seconds before restarting with a sudden burst of fast breaths. This can be quite startling for new parents. Things quiet down during the later stages of sleep when breathing becomes more regular. However, newborns spend about half of their sleep time in REM sleep, which means they have to connect sleep cycles more frequently. This transition from deep sleep back to light sleep can be challenging for young babies, and they may cry out as they make this shift.
In addition to breathing patterns, a baby's digestive system can also produce a range of noises, especially if they've fed just before settling off to sleep. Passing wind and having a bowel motion can cause a baby to be noisy during sleep. Interestingly, most babies don't burp unless they're awake. Some babies will wake and cry when they have a dirty nappy, while others are not bothered by it. It's important to follow the baby's lead and change them if they wake up, as this is a cue that they're uncomfortable.
While it's normal for newborns to be noisy sleepers, there are some instances where you should seek medical advice. If your baby is struggling to breathe, looks blue, or has any other signs of illness, such as fever or lethargy, don't hesitate to call an ambulance or your child's medical provider. Noisy breathing should always be checked by a doctor to rule out any underlying medical conditions.

They're learning to regulate their digestive and respiratory systems
Newborns are noisy sleepers because they are still learning to regulate their digestive and respiratory systems. Their little bodies are capable of making big sounds, especially when contrasted with the stillness of the night. While some babies are relatively quiet when they sleep, most make quite a lot of noise. A baby's age, development, and sometimes even illness can contribute to the noises they make while sleeping.
Babies are born with immature digestive systems, and the noises they make are a part of the maturing process. For example, passing wind or having a bowel movement can cause a baby to be noisy when sleeping. Additionally, if a baby has just fed before settling off to sleep, their digestion can produce a range of noises. Babies also tend to wake up and cry when they have a dirty nappy, although some are not bothered by it.
Newborns also have immature respiratory systems, and their breathing patterns differ from those of adults. They breathe more quickly than adults because they have smaller lungs and cannot hold a large volume of air and oxygen. Their breathing is not rhythmic, especially when they are young, and they tend to take many rapid and shallow breaths. Sometimes they take longer and slower breaths, followed by shallower intakes of air. The irregular breathing patterns of newborns can also be attributed to their tiny nasal passages, which are easily constricted by mucus, leading to grunts, groans, and whistles.
As babies grow and develop, the noises they make during sleep tend to lessen. By the time they are about six months old, their digestive and respiratory systems have matured, and their sleep becomes quieter. Their overall sleep cycles also lengthen, resulting in fewer sleep-wake disruptions.

Their airways are smaller
Newborns are noisy sleepers due to their immature and underdeveloped airways. Their tiny noses have even smaller air passages inside, and these can be further constricted by little particles of mucus, leading to a range of sounds such as grunts, groans, whistles, and squeaks.
Newborns have smaller airways and lungs, which means they breathe more quickly and take many rapid, shallow breaths. Their breathing is not rhythmic, and they tend to take longer and slower breaths followed by shallower intakes of air. This irregular breathing pattern can be a source of concern for new parents, but it is normal for newborns. Their breathing patterns change as they mature and their airways become bigger.
The size of a baby's airways can contribute to the noise they make while sleeping. Smaller airways can cause the air to move faster and create more noise. This is similar to how a narrower pipe can increase the speed and noise of flowing water. As babies grow, their airways expand, leading to quieter and more regulated breathing patterns.
In addition to their smaller airways, newborns are also learning to regulate their respiratory and digestive systems. This maturation process can result in irregular breathing and strange sounds, such as grunting and gurgling. These noises are typically not a cause for concern and are a normal part of a baby's development.
While most sleep noises are normal, there are some instances where noisy breathing may indicate a medical issue. For example, a hoarse cry or barking cough could signal croup or a blockage in the windpipe. If parents are concerned about their baby's breathing or overall well-being, they should consult their medical provider.

They're congested
Newborns are noisy sleepers because they are still developing their digestive and respiratory systems. Their airways are smaller, and they have irregular breathing patterns, which can cause congestion and noisy breathing.
If your baby is congested, there are a few things you can do to help them sleep more peacefully. Using a humidifier or air purifier can help to clear their airways and make it easier for them to breathe. Saline drops or gentle suction can also be used to clear any blockage in their nose. Creating a soothing sleep environment and ensuring your baby is well-hydrated can also promote better sleep.
Additionally, it is important to monitor your baby's congestion and breathing. If you notice any signs of distress, such as struggling to breathe, changes in colour, or a fever, seek medical attention immediately. Noisy breathing may also be a symptom of asthma or other respiratory conditions, so it is important to have your baby checked by a doctor if you have any concerns.
While congestion can be a reason for your newborn's noisy sleep, it is always important to consult your baby's medical provider if you have any concerns about their breathing or overall well-being. They can provide specific advice and recommendations based on your baby's individual needs.
