Newborn Sleeping With Mouth Open

Parents often notice their newborns sleeping with their mouths open and wonder if this is cause for concern. In most cases, there is a simple explanation for sleeping with mouths open, such as a stuffy nose or a natural preference, but sometimes it can point to an underlying problem. Understanding the possible reasons behind this habit and knowing when it's time to see a doctor can give parents more peace of mind.

Can newborns sleep with their mouths open?

Yes, newborns can sleep with their mouths open, but that's not always ideal.

Babies naturally prefer to breathe through their nose, so when they sleep with their mouth open, it could be a sign of nasal congestion, dry nasal passages, or other minor problems. In some cases, it may be a structural problem, such as enlarged tonsils or adenoids, which can affect the way they breathe.

If your newborn often sleeps with their mouth open, it's a good idea to see your pediatrician to rule out any underlying issues.

Why do some newborns sleep with their mouths open?

Here are some reasons why newborns sleep with their mouths open:

Nasal congestion

If your newborn has a stuffy nose, they may sleep with their mouth open to breathe more smoothly. Nasal congestion can be caused by colds, allergies, or even dry air, all of which can irritate a newborn's tiny nasal passages.

Nasal blockage

Sometimes structural problems such as narrowed or temporarily blocked nasal passages can make it more difficult for your baby to breathe through their nose, causing them to sleep with their mouth open.

Habitual mouth breathing

Some newborns develop the habit of breathing through their mouths, especially if the nasal congestion has been going on for some time. Once they start this habit, they will continue to breathe through their mouth even if their nose is clear.

Enlarged tonsils or adenoids

Enlarged tonsils or adenoids, although less common in newborns, can block airflow through the nose, making it necessary for them to breathe through their mouths. This problem is most often seen in older infants and toddlers but occasionally occurs at an earlier age.

Low muscle tone

Some infants have low muscle tone in their mouths and faces and they may find it difficult to close their mouths during sleep. This is usually associated with other conditions, but can also occur on its own.

Mouth Opening Posture

Certain sleeping positions or natural jaw alignment may cause babies to sleep with their mouths open, even if their nasal breathing is not obstructed.

If parents notice their baby consistently breathing with their mouth open, it's best to bring it up with their pediatrician to make sure there is no underlying health issue.

Is it safe for newborns to sleep with their mouths open?

In most cases, it's safe for newborns to sleep with their mouths open, but there are a couple of reasons why this may need attention:

Nasal congestion

If a newborn sleeps with his or her mouth open due to nasal congestion, it may lead to discomfort or interrupted sleep. While not inherently dangerous, prolonged nasal congestion may need to be addressed to improve breathing and quality of rest.

Dry mouth

Breathing through the mouth may lead to dryness in the mouth, which can cause irritation or increase the risk of oral infections. At the same time, not immediately harmful, persistent oral dryness should be monitored to avoid complications.

Potential medical conditions

In some cases, mouth breathing may point to an underlying problem, such as enlarged adenoids or blocked nasal passages. These conditions may interfere with normal airflow and should be evaluated by a pediatrician.

Interference with sleep quality

Mouth breathing can sometimes disrupt your baby's sleep cycle and lead to a decrease in sleep quality. Over time, this may affect their mood or feeding patterns.

While occasional mouth breathing is not a major problem, persistent open-mouth sleeping should be discussed with your pediatrician to rule out any issues and ensure your baby's overall health.

Breathe through noses vs. Breathe through mouths.

Here's a comparison between breathing through the nose and breathing through the mouth, including the pros and cons of each:

Breathing through the nose

Natural filtration

When your baby breathes through the nose, the tiny hairs and mucus in the nasal passages help filter out dust, allergens, and other particles. This provides cleaner air for the lungs.

Humidity and temperature control

Before the air reaches the lungs, the nasal passages humidify and warm the air, making it easier on the respiratory system. This is especially important for newborns because their airways are more sensitive.

Supporting feeding

Babies are born breathing through their noses, which allows them to breathe comfortably during feeding. This is why nasal congestion can interfere with feeding and make your baby fussy.

Better oxygen exchange

Nasal breathing promotes slower, deeper breathing, which improves oxygen exchange and helps the body function more efficiently.

Breathing through the mouth

Alternate method when the nose is blocked

Mouth breathing can be a useful backup method when the nose is blocked or obstructed, ensuring that your baby still gets enough air.

Dryness and irritation

Unlike the nose, the mouth cannot filter, humidify, or heat air. This can lead to dryness in the mouth and throat, increasing the risk of irritation or infection.

Less efficient breathing

Oral breathing usually results in faster, shallower breaths, which may not provide oxygen as slowly as nasal breathing.

Potential for habit formation

If your baby keeps breathing through their mouth, even if their nose is clear, a habit can form. Over time, this may affect oral health or facial development.

In general, it is best to encourage newborns to breathe through the nose, but breathing through the mouth can be used as a backup when needed. Parents should monitor their baby's breathing pattern and consult their pediatrician if they notice persistent mouth breathing.

What to do if newborns sleep with their mouths open?

If your newborn sleeps with his or her mouth open, parents can take the following steps:

Check for nasal congestion.

Parents should look for signs of nasal congestion, such as noisy breathing or mucus. Using saline nasal sprays and bulb syringes can help unclog your baby's nasal passages, making it easier for them to breathe through their nose.

Use a humidifier

Adding a humidifier to your baby's room will keep the air moist and prevent your baby's nose and throat from drying out. This is especially useful during the winter months when indoor air is dry.

Ensure proper sleeping position.

Parents can ensure that their baby sleeps on his or her back as this is the safest position, and it also helps with breathing. Slightly elevating the head of the crib (under the guidance of your pediatrician) can also improve air circulation.

Troubleshooting allergens

Parents should check their baby's sleeping environment for allergens that may irritate the nasal passages, such as dust or pet dander. Keeping the surroundings clean and free of irritants can help reduce nasal congestion.

Monitor other symptoms

Be sure to consult your pediatrician if your baby sleeps with his or her mouth always open or experiences other symptoms such as snoring, feeding difficulties, or slow weight gain. These signs may indicate an underlying problem that needs attention.

Avoid overheating

Overheating can lead to dryness and congestion. Parents should dress their baby in lightweight pajamas and keep the room temperature comfortable, usually between 68-72 degrees Fahrenheit.

These steps can help parents address common causes of mouth breathing and improve their newborn's quality of sleep. If the problem persists, it is best to consult your pediatrician.

Conclusion

In most cases, a newborn sleeping with his or her mouth open is not a serious problem, but sometimes it can be an underlying issue, such as a stuffy nose or structural problem. Parents can take simple measures such as clearing the baby's nose, using a humidifier, and keeping the sleeping environment clean to help the baby breathe better.

If this behavior persists or is accompanied by other symptoms, it is best to consult a pediatrician. Understanding the reasons behind mouth breathing can help parents feel more confident in ensuring their baby's health and comfort.
