Children's Cough: Causes and Treatments

A child's little body can make a big sound when wracked with cough. To help your child cope with a cough, know the common causes and treatments you can try at home.

Children and Cough: Common Causes and Treatments

A cough is usually a sign your child's body is trying to rid itself of an irritant, from mucus to a foreign object. Common causes of cough include:

  • Infection. Colds, flu, and croup can all lead to a lingering cough for kids. Colds tend to cause a mild to moderate hacking cough; the flu a sometimes severe, dry cough; and croup has a "barking" cough with noisy breathing.
  • Acid reflux. Symptoms in children may include coughing, frequent vomiting/spitting up, a bad taste in the mouth, and heartburn. Treatment for reflux depends on a child's age, health, and other issues. Try these three tips: Remove trigger foods from their diet (often chocolate, peppermint, fried, spicy, fatty foods, and carbonated drinks). Eat at least two hours before bedtime. And eat smaller meals. See your doctor if you are concerned about your child's acid reflux.
  • Asthma can be tough to diagnose, because symptoms vary from child to child. But a wheezing cough, which may get worse at night, is one of many asthma symptoms. The other may be a cough that appears with increased physical activity or during play. Treatment for asthma depends on what's causing it, and may include avoiding triggers like pollution, smoke, or perfumes. See your doctor if you think your child has asthma symptoms.
  • Allergies/Sinusitis can cause a lingering cough, as well as an itchy throat, runny nose, watery eyes, sore throat, or rash. Talk to your child's doctor about allergy tests to find out which allergens cause the problem, and ask for advice on how to avoid that allergen. Allergens can include food, pollen, pet dander, and dust. Your doctor may also recommend allergy medication or allergy shots.
  • Whooping cough, also called pertussis, is characterized by back-to-back coughs, followed by an inhale that has a "whooping" sound. Other symptoms may include runny nose, sneezing, and low fever. Whooping cough is contagious, but easy to prevent with a vaccine. Whooping cough is treated with antibiotics.
  • Other reasons children cough: A child may also cough out of habit after having been sick with a cough; after inhaling a foreign body like food or a small toy; or after exposure to irritants like pollution from cigarettes or fireplace smoke.

A Word About Children and Cough Medicine

Medication can't cure colds or flu, but hard candies or cough drops can help relieve a sore throat caused by coughing. Because of choking hazards, only give hard candies or cough drops to children over age 4. DO NOT give honey-based cough drops to children age 1 or younger. Moist air can help children cope with croup; try a warm, steamy bathroom, or cool morning air. For lingering coughs in an asthmatic, your child may need to take steroids or other medications prescribed by the doctor.

Don't give cough medicine to children under age 4. Not only are these drugs not approved for very young children, there's no proof that they benefit them, either.

Also important: Never give aspirin to children under age 18. Aspirin in children may cause Reye Syndrome, a rare but serious brain disease.
