What Is Croup in Babies?

Croup, also known as laryngotracheobronchitis, is a viral infection that affects the upper airway tract in babies, blocking proper breathing, and causing a distinctive bark-like cough. Croup in babies causes the windpipe and voice box to swell, which makes it difficult for the baby to breathe. Croup in babies under 3 months occurs mostly in winter and can be recognised as the cough sounds worse than it should.

It is important for parents of newborn children to be informed about causes, treatments and symptoms, as the occurrence of croup in babies under 6 months is common. Croup does not occur frequently in older kids, as the size of their windpipe increases with age and physical development over the years.

There are two types of croup – viral and spasmodic. Viral croup is the more common type and is caused due to a virus known as human parainfluenza virus (HPIV). Spasmodic croup is caused due to an allergy or the reflux of the stomach.

How Does It Sound Like?

Croup in babies typically sounds like a harsh, barking cough accompanied by a high-pitched or squeaky noise when they breathe. This noise is often referred to as “stridor” and can be more noticeable when the baby inhales. Croup can also cause hoarseness and difficulty breathing. 

What Are the Causes of Croup?

How do babies get Croup? It is vital for parents to understand what causes Croup in children, so as to take appropriate precautions to avert it.

1. Viral Infection

The most common cause of croup are viruses, but it can also be caused by allergies, bacteria, and reflux from the tummy. There are multiple viruses that cause croup, but the most common virus is called the parainfluenza virus. Some other viruses that may cause croup include respiratory syncytial virus (RSV), influenza virus, measles, adenovirus, and enteroviruses.

2. Contact With an Infected Person

A baby may also contract the disease if he comes in contact with another child or adult who is infected by the causative virus. Since it is a respiratory infection, it is mostly contagious.

Common Signs and Symptoms of Croup

Croup starts like any other cold or cough, and that’s why, initially, it may be slightly difficult to differentiate and identify. However, soon, what looks like a normal stuffy or runny nose and a fever, may turn out to be something more severe. The most common signs and symptoms of croup are:

Common Signs and Symptoms of Croup in babies

  1. Runny nose
  2. Chest congestion
  3. Hoarse cough
  4. A cough that develops into a “seal’s bark” (also known as croup barking cough)
  5. Swollen lymph nodes
  6. Eye redness
  7. Rashes
  8. Fever
  9. Stridor (a high-pitched sound that is mostly noticed as the child breathes in or out)

Symptoms of the common cold can either precede or linger after croup. There are also some signs that are indicative of the severity of the condition and require immediate medical attention. These symptoms are of the following types:

  1. If the baby’s airway is obstructed, he will look worried and disturbed, and won’t show interest in playing or doing other activities; he might constantly try to get air.
  2. He will not be able to sleep or lie down and will constantly sit up and cough.
  3. The dent right above the breastbone will cave with each breath.

Is Croup Contagious in Babies?

Yes, it can be. A child can catch the causative virus through direct contact with someone who has been infected, through droplets dispersed into the air when the infected child or adult coughs. Secretions from an infected person can be contagious, too, and that’s why proper precautionary measures must always be taken. It is also wise to ensure that your baby’s hygiene is well-maintained at all times.

How Long Does Croup Take to Go Away?

This is a common question that plagues parents. Croup usually lasts for 3 to 7 days, but there is a possibility that it can last for up to 2 weeks, depending on the severity. It generally peaks on the 2nd or 3rd night, and during this time, you should engage in ways to calm and relieve your baby. The symptoms of cold and flu might linger and can leave the baby and you, tired.

How Is Croup Diagnosed?

Physical examination is the most common method to diagnose croup. Doctors observe the child’s breathing and use a stethoscope to examine it, along with the child’s throat. X-rays are also conducted, to rule out the possibility of any other disease or condition. Sometimes, when an in-clinic visit is not possible, the doctor may listen to the breathing and cough over the phone, for the right diagnosis.

What Is the Treatment for Croup?

Treatment for Croup in babies depends on multiple parameters, such as the child’s overall health and well-being, medical history, age, the extent of and seriousness of the disease, as well as the child’s tolerance to allergies to particular medicines.

To understand how to treat croup cough in babies, it is important you are equipped with prerequisite knowledge. In case the infection is severe, hospitalisation may be considered, especially if your child has to be monitored at all times.

Doctor giving medicine to baby

There are four types of medical treatments that can be followed to treat croup:

  1. Medicines are given through nebulisation to open the airway and increase the inflow and outflow of air.
  2. Injecting medication to reduce the swelling of the airways.
  3. Use of steroids, oral or through-the-mouth medication to reduce the swelling.
  4. In some instances, a breathing tube is inserted into the child’s windpipe.

Are There Home Remedies to Ease the Symptoms of Croup?

Yes – a majority of croup cases can be treated at home by using natural remedies. Some home remedies for croup in babies include:

  1. Keep your child calm. Crying and agitation can only lead to an increase in the obstruction of the airway and result in complications. Croup can frighten a small child, and crying can lead to worsening the stridor (the harsh sound). Sit your baby upright in your lap, sing soft lullabies, and read to him. Breastfeeding also acts as a pacifier in such a situation.
  2. Humidity and steam can help in clearing the air passages and easing the breathing process. Steam up your bathroom, and sit with your baby in your lap. There should be an immediate improvement in the next 10 to 15 minutes.
  3. Use a cool-mist humidifier or vaporiser, for inhalation of the cool mist. Once you let the mist near the baby to promote easy breathing, you should see an improvement. You can use a hot vaporiser, too, but it should not be brought too close to the baby.
  4. Consult a doctor to treat the fever.
  5. Finally, offer fluids and encourage rest at all times.

In case your baby’s cough improves during the day, but comes back at night, it is time to visit a doctor. Additionally, it is always best to consult your paediatrician before administering any baby cough remedies for your 4 months old.

Can Croup Be Prevented?

There is no current vaccination for croup. However, avoiding exposure to contaminated objects and contagious sneezing and coughing can prevent croup. Also maintain your baby’s hygiene at all times, especially during flu or common cold season.

When Should You Call a Doctor?

If you are concerned that your child’s croup is not improving, despite using home remedies, it’s time to call a doctor. Additionally, if you see your baby turning breathless or pale, it’s time to take him to the emergency room.


1. Is It Possible That My Child Can Get Croup Again?

Yes, it’s possible for a child to get croup more than once, as it can be caused by different viruses. Recurrence is not uncommon.

2. How Many Times Can My Infant Have Croup?

Croup can affect infants multiple times, but it tends to be more common in children between the ages of 6 months to 3 years. Most children outgrow it as their airways grow larger.

3. Why Is Croup Rare in Babies Under 6 Months?

Croup is rarer in babies under 6 months because their airways are naturally narrower and less developed, making them less susceptible to the characteristic croup symptoms seen in older infants and children.

Croup can be treated at home, but you must take precautions to guard your baby against the infection. Babies tend to feel uneasy when affected, so ensure that they stay healthy, and are monitored at all times.
