Cough is one of the ways for the body to clear clearing mucus, phlegm, postnasal drip, or a foreign body. A baby could cough for various reasons. While a cough is an essential function, it is not healthy for an infant to cough too much. Seek medical help if your baby coughs a lot (1).

Types Of Cough In Babies

Cough can be classified based on character, duration, quality, and timing as follows (2) (3).

  • Acute cough: A rapid onset of cough that lasts less than three weeks.
  • Subacute cough: Lasts around three to eight weeks.
  • Chronic or persistent cough: Lasts more than eight weeks, usually from allergies or asthma. It can also be due to infections.
  • Dry cough: Non-productive cough where there is no sputum production.
  • Wet cough: Productive cough with sputum.
  • Nocturnal cough: Occurs at night and can be due to postnasal drip (mucus from nose and sinus drain to throat) or asthma.
  • Daytime cough: Occurs during the day and can often be allergic to smoke, air fresheners, pets, etc.

Cough can be classified based on their character, which is the nature of air’s movement during the cough (3).

  1. Barking cough: It can be due to swelling in the upper airway, usually the larynx and trachea, due to the parainfluenza virus that interferes with breathing. It may start suddenly during the night. You may hear stridor, which is a loud noise from harsh breathing while inhaling air. It is caused by croup (4).
  1. Whooping cough: It is a type of continuous cough without gaps to breathe in between coughing. The whooping sound is heard when the baby takes a deep breath at the end of the coughing episode. It is caused by pertussis infection by bacterium Bordetella pertussis and is common in unvaccinated babies under the age of one year (5).
  1. Staccato cough: The baby breathes in between each cough. It is a characteristic symptom of chlamydial pneumonia in babies (6).

Symptoms With Cough In Babies

Coughing by itself can be a symptom of respiratory tract infection or a simple reflex to an irritant such as smoke. The following symptoms could also occur along with cough in babies (3):

  • Cough with wheezing: Wheezing is a whistling sound that occurs while breathing out. It can be due to lower airway tract infections such as asthma or bronchiolitis or due to foreign bodies such as food or small toys.
  • Cough with a fever: Your baby may get a mild fever with a common cold. Body temperature more than 102°F (39°C) can be due to infections such as pneumonia.
  • Cough with vomiting: If your baby has asthma or cold, they may vomit due to excess mucus accumulated in the stomach due to swallowing it. Sometimes, they may vomit due to the stimulation of gag reflex while coughing.

When Should You Call The Doctor?

It is recommended to contact a pediatrician if your baby has a cough. Your baby may require immediate medical care in the following circumstances with cough (3) (7).

  • Difficulty in breathing
  • Breathing faster than usual
  • Blue color of the lips, face, or tongue
  • High fever
  • High fever with cough, without a runny or stuffy nose
  • High or mild fever in infants less than three months old
  • Cough more than few hours in infants younger than three months
  • Whooping sound after cough
  • Coughing up blood
  • Stridor (sharp sound while breathing)

  • Tiredness and irritability
  • Dehydration symptoms such as dry mouth, sunken eyes, no tears, and less urine

  • Cough medicines are usually not recommended for children.

It is advised not to give over-the-counter cough syrup or cough drops to your baby since they have the risk of causing serious complications such as slow breathing, choking, etc. (9).

How To Prevent Cough In Babies?

The following factors may help prevent cough in babies.

  • You can prevent exacerbation of asthmatic cough by following prescribed medication.
  • Do not give small toys, which may be choking hazards.
  • Follow proper feeding techniques to avoid food aspirations.
  • Get recommended vaccinations on time.
  • Try to protect your baby from contracting viral illnesses such as flu or cold if you have it.

Home Treatment For Cough In Babies

The following home remedies may help relieve cough in babies (7):

  • Give plenty of fluids or breastmilk to soothe the throat and prevent dehydration.
  • The baby will need more rest.
  • Prevent the drying of the nose and throat by using a cool-mist vaporizer or humidifier near a baby crib.
  • Saline drops can be used if your baby has a stuffy nose. Bulb syringe or other suction tools can be used to clean the nose in infants.
  • Dress your baby in warm clothing in winter months.
  • Keep away irritants such as pets, air fresheners, or dust from your baby.

You should not give honey to a baby younger than one year. Instead, one to three spoons of warm, clear fluid might help provide relief to babies of three months to one year of age. These fluids can be breast milk or formula. If your baby is less than three months old, then do not try home remedies but see a doctor. (10).
