1. Why do babies cough in their sleep?

It is not uncommon for babies to cough in their sleep, and there can be several reasons behind this. One possible explanation is that babies have smaller airways compared to adults, making them more prone to irritation or blockages. The position they sleep in can also contribute to coughing, as lying flat may cause mucus or saliva to accumulate and trigger a cough reflex.

Another common cause of coughing in babies during sleep is postnasal drip. This occurs when excess mucus from the nose drips down the back of the throat, leading to irritation and coughing. Babies are particularly susceptible to postnasal drip due to their underdeveloped sinuses and nasal passages.

In some cases, a baby’s nighttime cough may be a symptom of an underlying respiratory infection, such as a cold or flu. These infections can cause inflammation in the airways and lead to increased mucus production and coughing. If your baby has other symptoms like fever, congestion, or difficulty breathing, it is important to consult a pediatrician for proper evaluation and treatment.


Possible causes of coughing in babies during sleep:

  • Smaller airways
  • Position while sleeping
  • Postnasal drip
  • Respiratory infections


  • Elevate your baby’s head slightly during sleep by using a firm pillow or adjusting the crib mattress.
  • Maintain a clean sleeping environment free from dust and allergens.
  • If your baby has a stuffy nose, use saline drops or a bulb syringe to clear their nasal passages before bedtime.

2. Is it normal for babies to cough while sleeping?

Yes, it is generally considered normal for babies to cough while sleeping. As mentioned earlier, babies have smaller airways and are more susceptible to irritants or blockages that can trigger a cough reflex. Additionally, babies produce more mucus than adults, which can lead to coughing as the body attempts to clear the excess mucus from the airways.

In most cases, a baby’s nighttime cough is harmless and will resolve on its own without any intervention. However, if you notice any concerning symptoms accompanying the cough or if the cough persists for an extended period of time, it is advisable to seek medical advice.

Situations when baby’s nighttime cough may be considered normal:

  • Occasional mild coughing without other symptoms
  • Coughing due to postnasal drip or mucus accumulation
  • Coughing resolves quickly and does not interfere with sleep or feeding


  • Monitor your baby’s overall health and behavior during waking hours to ensure they are not experiencing any other concerning symptoms.
  • If your baby’s sleep or feeding patterns are disrupted due to frequent or intense coughing, consult a pediatrician for further evaluation.

3. What are the common causes of coughing in babies during sleep?


Allergies can be a common cause of coughing in babies during sleep. Dust, pollen, pet dander, or certain foods can trigger an allergic reaction in infants, leading to coughing episodes. It is important for parents to identify and minimize exposure to potential allergens in their baby’s environment.

Respiratory Infections

Respiratory infections such as colds, flu, or bronchiolitis can also cause coughing in babies during sleep. These infections often result in congestion and inflammation of the airways, leading to coughing as the body tries to clear mucus.

Gastroesophageal Reflux (GER)

GER occurs when stomach acid flows back into the esophagus, causing irritation and triggering a cough reflex. This condition is more common in infants and can worsen during sleep when lying flat. Elevating the head of the baby’s crib may help alleviate symptoms.

4. How can I differentiate between a harmless cough and a concerning one in my baby’s sleep?

It is important for parents to be able to distinguish between a harmless cough and a concerning one in their baby’s sleep. Some signs that may indicate a more serious issue include:


If the cough persists for more than two weeks or is accompanied by other symptoms such as fever, difficulty breathing, or wheezing, it may be necessary to seek medical attention.


A harsh or barking cough could be indicative of croup, while a wet or productive cough with yellow or green mucus may suggest a respiratory infection that requires medical evaluation.

Difficulty Sleeping:

If the baby’s cough is causing significant disruption to their sleep or if they are experiencing poor appetite or weight loss, it is advisable to consult a healthcare professional.

It is always better to err on the side of caution and consult a pediatrician if there are any concerns about the baby’s coughing during sleep.

5. Are there any specific remedies or treatments for babies who frequently cough during sleep?

While treatment options may vary depending on the underlying cause, there are some general remedies that can help alleviate coughing in babies during sleep:

– Keeping the baby’s sleeping environment clean and free from potential allergens such as dust, pet dander, or smoke.
– Using a cool-mist humidifier in the baby’s room to keep the air moist and reduce irritation in the airways.
– Elevating the head of the crib slightly to help with postnasal drip and reflux-related coughing.
– Ensuring proper hydration by offering frequent breastfeeding or bottle feeding sessions.
– Avoiding exposure to cigarette smoke, as it can worsen respiratory symptoms.

However, it is important to consult with a healthcare professional before administering any over-the-counter medications or home remedies, especially for infants under six months old.

6. Can environmental factors, such as dust or allergens, contribute to a baby’s nighttime coughing?

Allergens and Dust Mites

Environmental factors can indeed play a role in causing nighttime coughing in babies. Allergens, such as dust mites, pet dander, pollen, and mold spores, can trigger respiratory symptoms like coughing. Dust mites are microscopic creatures that thrive in warm and humid environments. They feed on dead skin cells and their droppings can become airborne when disturbed. When babies inhale these allergens, it can irritate their airways and lead to coughing episodes during sleep.

Preventing Exposure

To reduce your baby’s exposure to environmental triggers, it is important to keep their sleeping environment clean and free from allergens. Use hypoallergenic bedding covers to protect against dust mites and wash bedding regularly in hot water. Vacuum carpets and rugs frequently using a vacuum cleaner with a HEPA filter to trap allergens effectively. Avoid smoking near your baby or exposing them to secondhand smoke as it can worsen respiratory symptoms.


– Keep the bedroom well-ventilated by opening windows or using an air purifier.
– Regularly clean stuffed animals or consider keeping them out of the bedroom.
– Avoid using scented products like air fresheners or perfumes that may trigger allergies.

7. At what age does a baby’s coughing during sleep typically decrease or disappear?

Coughing during sleep is common in infants and young children due to their developing immune systems and smaller airways. As babies grow older, their respiratory system matures, making them less prone to frequent coughing episodes during sleep. Typically, by the age of 6 years old, most children experience a significant reduction in nighttime coughing. However, it is important to note that every child is different, and some may continue to have occasional coughing episodes during sleep beyond this age.

Factors Affecting Coughing Duration

Several factors can influence the duration of nighttime coughing in babies. These include their overall health, exposure to environmental irritants, such as smoke or allergens, and any underlying respiratory conditions they may have. If your baby’s coughing persists or worsens over time, it is advisable to consult a pediatrician for further evaluation and guidance.


– Provide a humidifier in your baby’s bedroom to help alleviate dry air that can trigger coughing.
– Ensure your baby stays hydrated by offering them plenty of fluids throughout the day.
– Follow proper hand hygiene practices to reduce the risk of respiratory infections.

8. Should I be concerned if my baby starts coughing more frequently or intensely during sleep?

If your baby suddenly starts coughing more frequently or intensely during sleep, it is natural to feel concerned. While occasional coughing is normal, an increase in frequency or intensity could indicate an underlying issue that requires attention. It is essential to monitor other accompanying symptoms such as fever, difficulty breathing, wheezing, or changes in appetite.

Possible Causes

There are several potential causes for increased nighttime coughing in babies. It could be due to a respiratory infection like bronchiolitis or pneumonia, allergies triggered by environmental factors like dust mites or pet dander, asthma exacerbation, acid reflux (GERD), or even a sign of underlying lung conditions. Consulting a pediatrician will help determine the cause and appropriate treatment for your baby’s specific situation.


– Keep track of when and how often your baby experiences nighttime coughing episodes.
– Note any additional symptoms or triggers that may be associated with the coughing.
– Follow any instructions provided by your pediatrician for managing your baby’s coughing.

9. Are there any preventive measures I can take to reduce my baby’s nighttime coughing episodes?

Maintaining a Clean Environment

Taking preventive measures can help reduce your baby’s nighttime coughing episodes. Keeping their sleeping environment clean and free from potential irritants is crucial. Regularly dust and vacuum the room, wash bedding in hot water, and consider using hypoallergenic covers to protect against dust mites. Avoid exposing your baby to secondhand smoke or strong odors that may trigger respiratory symptoms.

Proper Hydration

Ensuring your baby stays hydrated is also important in preventing coughing episodes during sleep. Offer them plenty of fluids throughout the day, especially if they have a respiratory infection or are experiencing dry air in their bedroom. Proper hydration helps keep the airways moist and reduces irritation that can lead to coughing.


– Use a cool-mist humidifier in your baby’s bedroom to add moisture to the air.
– Dress your baby appropriately for sleep, considering the temperature and humidity of the room.
– Avoid exposing your baby to people who have colds or respiratory infections.

10. What are some signs that indicate when it is necessary to consult a pediatrician about my baby’s nighttime coughing?

Persistent Coughing

If your baby’s nighttime coughing persists for an extended period or becomes more frequent and intense, it is advisable to consult a pediatrician. Persistent coughing could be a sign of an underlying respiratory condition that requires medical attention.

Accompanying Symptoms

Other accompanying symptoms should also be taken into consideration when deciding whether to consult a pediatrician. If your baby experiences difficulty breathing, wheezing, fever, loss of appetite, or shows signs of distress during coughing episodes, it is important to seek medical advice promptly.


– Keep a record of your baby’s coughing episodes and any associated symptoms.
– Follow your parental instincts. If you feel concerned about your baby’s health, it is always better to consult a healthcare professional for proper evaluation and guidance.

In conclusion, while it is common for babies to cough in their sleep, it is important for parents to monitor the frequency and severity of these coughs. If a baby’s coughing persists or worsens, seeking medical advice is recommended to ensure their well-being.

Is it normal for babies to cough in their sleep?

This usually happens because when a child is lying down to sleep, the mucus in their nose and sinus cavity drips down into their throats. This causes irritation in the throat, which then triggers a cough.

When should I be concerned about my baby coughing at night?

Contact your doctor if you experience difficulty breathing, wheezing, or if your cough persists for more than three weeks. Additionally, if you believe your child requires medical attention, it is advised to seek professional help.

Why does my baby cough in his sleep but not sick?

The cause of the cough in toddlers at night is due to mucus from the sinuses dripping into the throat when they are lying down. This can also be triggered by asthma, which makes the airways more sensitive after bedtime. If your toddler has an intermittent cough that worsens at night and during activity, it is recommended to consult with a pediatrician.

Why is my baby coughing but not sick?

Coughing is commonly linked to respiratory illnesses like colds, bronchiolitis, croup, flu, and pneumonia. However, a cough can also be triggered by allergies, ingesting a foreign object, or temporary irritants like paint fumes or tobacco smoke.

What does RSV cough sound like?

Infants and toddlers who have RSV usually experience symptoms of upper respiratory tract infection, such as fever and a runny nose or congestion, for about two to four days. These symptoms are then followed by lower respiratory tract symptoms, including a cough that sounds wet and forceful with increased difficulty in breathing.

Can teething cause coughing at night?

Excessive drooling during teething can lead to coughing in babies as the drool may go down their throat. If there are no signs of a cold or allergies causing nasal congestion, this could be the reason for the coughing.
