How to Get Rid of a Cough in Kids: Safe Home Remedies

Honey given before bedtime is the most evidence-backed home remedy for a child’s cough, consistently outperforming placebo and matching common over-the-counter cough suppressants in clinical trials. But honey is only safe for children older than 12 months, and it is far from the only thing you can do at home. The toolbox includes cool-mist humidifiers, saline nose drops, vapor rubs, and simple comfort measures like warm fluids and an extra pillow. Knowing which of these actually work, which carry real risks, and when a cough needs a doctor rather than a kitchen remedy is worth sorting out before the next cold hits your household.

Why Kids Cough So Much in the First Place

Coughing is a protective reflex, not a disease. When something irritates the airways, nerve endings send signals to the brainstem, which triggers the forceful burst of air we recognize as a cough. In children with a common cold, that irritation comes from a combination of postnasal drip, airway inflammation, and mucus buildup.¹ Because coughing clears the airways, suppressing it entirely is rarely a good idea in childhood. A child whose cough reflex is impaired can end up sicker, not better.²

Children also get more respiratory infections than adults because their immune systems are still learning to recognize viruses. Six to eight colds per year is normal for a young child, and each one can leave a lingering cough for two to three weeks. The goal of home remedies is not to silence the cough completely but to ease the irritation enough that your child can sleep, eat, and stay comfortable while the infection runs its course.

Honey Before Bed

Honey has the strongest evidence behind it of any home remedy for pediatric cough. A double-blind randomized trial gave children aged one to five years either honey or a placebo (date syrup) on the night of an upper respiratory infection. All groups improved from the previous night, but the honey groups improved more on every measure parents reported, including cough frequency, cough severity, and sleep quality.³ An earlier trial compared honey head-to-head with dextromethorphan (the active ingredient in most OTC cough syrups) and found honey was better than no treatment for cough frequency, while dextromethorphan was not. The two performed about equally.⁴

A systematic review pooling multiple trials confirmed that honey tends to reduce cough frequency more than placebo or standard cough medication, with similar improvements in sleep, though the overall quality of evidence was rated low to very low.⁵ That “low quality” label mostly reflects the difficulty of blinding honey in a study. Nobody has claimed that honey is a powerful drug. Its advantage over placebo is real but modest, and it comes with almost no downside for children old enough to have it safely.

Half a teaspoon for ages one to five and a full teaspoon for older children, given 30 minutes before bed, is a common dosing approach. The type of honey does not seem to matter much based on the available trials, so you do not need to track down a specific variety.

The Under-One Rule for Honey

Honey is off-limits for babies younger than 12 months. The reason is infant botulism: honey is the only consistently confirmed dietary source of Clostridium botulinum spores, which can germinate in an infant’s immature gut and produce a dangerous toxin.⁶ Health authorities worldwide advise against giving honey before 12 months, though warning labels on honey jars remain voluntary in many countries, and awareness among caregivers varies.⁷ The risk is small in absolute terms. In one U.S. study, only about 16 percent of infant botulism cases had a history of honey exposure, but the odds ratio was nearly tenfold.⁸ After age one, the gut is mature enough to handle the spores without incident.

For babies under a year with a cough, your options narrow to saline drops, a cool-mist humidifier, extra fluids, and suctioning mucus from the nose. If the cough in an infant is persistent, worsening, or accompanied by difficulty breathing, that warrants a call to the pediatrician rather than a home remedy.

Vapor Rubs

Mentholated vapor rubs are a staple of the home-remedy tradition, and there is a randomized trial supporting their use. Children aged two to eleven with nighttime cold symptoms were assigned to receive a vapor rub containing camphor, menthol, and eucalyptus oil, plain petrolatum, or no treatment. Parents rated the vapor rub best for cough severity, congestion, and sleep difficulty. The rub outperformed both petrolatum and no treatment on most outcomes.⁹

The mechanism is not what most people assume. Menthol does not actually open the airways or reduce mucus production. Instead, it activates cold-sensitive receptors on nerve endings in the skin and airway lining, creating a sensation of easier breathing without measurably changing airflow.¹⁰ That cooling sensation can still be genuinely soothing and may help a child fall asleep.

A few cautions apply. Vapor rubs should go on the chest or neck, never under or inside the nose, and never on broken skin. They are not recommended for children under two. If a child accidentally eats a vapor rub, the concentrated camphor and menthol can cause nausea, vomiting, and in serious cases, breathing difficulties.¹⁰ Keep the jar out of reach.

Cool-Mist Humidifiers, Not Steam

Adding moisture to bedroom air can ease that dry, scratchy feeling that makes nighttime coughing worse. But the choice between a cool-mist humidifier and a hot steam vaporizer matters. Steam vaporizers produce water hot enough to cause serious burns. Between 2001 and 2006 at one center alone, 27 children were treated for scald injuries linked to breathing-humidified-air setups, including steam burns to the hands of toddlers and larger scalds from tipped containers of hot water.¹¹ Other case reports document partial-thickness burns from steam vaporizers placed near cribs or beds.¹² Toddlers are the most at risk, often reaching into the steam outlet or pulling the device over.¹³

A cool-mist humidifier gives you the same moisture benefit without the burn hazard. Place it near but not directly touching the child’s bed, clean it regularly to prevent mold growth, and empty it during the day. If the room starts to feel damp or you notice condensation on windows, turn it down. Over-humidifying can encourage dust mites and mold, which make respiratory symptoms worse in the long run.

Saline Nose Drops and Nasal Irrigation

Much of a child’s nighttime cough comes from mucus dripping down the back of the throat. Saline nose drops or a gentle nasal rinse can thin that mucus and reduce the drip. In children with chronic sinusitis, a hypertonic saline nasal wash significantly improved cough scores compared to normal saline, which barely moved the needle on cough at all.¹⁴

For a regular cold, the picture is a bit more mixed. A systematic review of saline nasal irrigation for acute upper respiratory infections in children found it helped with nasal symptoms like congestion and runny nose, but did not show a clear improvement in respiratory symptoms like coughing itself.¹⁵ In practice, many parents and pediatricians find that clearing the nose before bed still helps with cough indirectly, because less drip means less irritation. For babies and very young children, a few saline drops followed by gentle bulb-syringe suctioning is the easiest approach. Older children can use a squeeze bottle or neti pot with pre-mixed saline packets.

Warm Fluids and Simple Comfort Measures

Staying well hydrated helps keep mucus thin and easier to clear. Warm liquids like broth, warm water with lemon, or herbal teas (for children old enough to drink them safely) have an additional soothing effect on an irritated throat. There is no rigorous trial proving that warm water cures a cough, but the logic is straightforward: a hydrated airway produces less sticky mucus, and warm liquid physically coats and calms inflamed throat tissue. Surveys of parents show that herbal teas, citrus juices, and honey-based drinks are among the most commonly used non-medication approaches.¹⁶

Elevating the head of the bed or adding an extra pillow for older children can also reduce postnasal drip at night. For toddlers still in a crib, you can place a rolled towel under the mattress at the head end to create a slight incline, though this should never be done in a way that creates a suffocation risk for infants. Keep the angle gentle.

Why OTC Cough Medicines Are Not Recommended for Young Kids

It is tempting to reach for a children’s cough syrup at the pharmacy, but the evidence behind them is surprisingly weak. Studies have generally not found the active ingredients in cold and cough medicines to be effective for symptom relief in children. Both the FDA and the American Academy of Pediatrics recommend against their use in children under two, citing a lack of efficacy and the potential for serious side effects.¹⁷ Many pediatricians extend that caution to children under six.

The risk is amplified by the fact that most OTC cough and cold products combine multiple active ingredients. A parent who gives a cough syrup and a separate decongestant may accidentally double a dose of one ingredient. Case reports document serious toxicity and fatalities in children linked to these medications, both from accidental overdoses and from therapeutic use at labeled doses.¹⁸ Home remedies like honey have the advantage of being at least as effective, with a much wider safety margin.

Thyme and Ivy Syrups

In parts of Europe, herbal syrups combining thyme and ivy extracts are commonly sold for children’s coughs. The evidence is limited but moderately encouraging. A randomized controlled trial comparing a thyme-ivy syrup to dextromethorphan in children found that cough severity dropped by about 87 percent in the herbal group versus 81 percent in the dextromethorphan group over the treatment period.¹⁹ A postmarketing study in children and adolescents taking a thyme-ivy syrup for acute bronchitis found that coughing fits dropped by about 80 percent after ten days, with physicians rating tolerability as good or very good in over 96 percent of cases.²⁰

These results are promising but come with caveats. Most trials are small, and postmarketing surveillance studies lack a control group. An updated systematic review of ivy leaf preparations for acute upper respiratory infections found one trial showing a short-lived reduction in coughing fits compared to standard care, but the difference faded at later follow-up visits.²¹ If you want to try a thyme-ivy syrup, look for a product made specifically for children with age-appropriate dosing on the label. These syrups are generally well tolerated, but “herbal” does not mean risk-free, so follow the dosing instructions.

The Surprisingly Strong Placebo Effect

One thing worth knowing about pediatric cough research is that placebos work remarkably well, at least as far as parents can tell. A randomized trial in infants and toddlers gave some children agave nectar (which has no known cough-suppressing properties), others a true placebo, and a third group nothing at all. Both the agave group and the placebo group improved compared to no treatment, and the difference between agave and placebo was negligible. Parents perceived that their child was getting better simply because they had been given something.²²

This does not mean home remedies are pointless. It means that the act of caring for a sick child, giving them something soothing, paying attention to their symptoms, has a measurable effect on how parents (and possibly children) perceive the illness. A spoonful of honey or a warm drink before bed may work partly because it is genuinely soothing and partly because it is a comforting ritual. Both of those things are real, and neither one is a reason to stop doing it.

Reducing Environmental Irritants

If your child’s cough lingers or keeps coming back, look at what they are breathing at home. Tobacco smoke is the most well-documented environmental trigger. Children exposed to secondhand smoke have significantly higher rates of respiratory symptoms. One study found that kids exposed to environmental tobacco smoke had respiratory symptoms at a rate of 56 percent compared to 31 percent among unexposed children.²³ If anyone in the household smokes, doing so outside and away from the child makes a measurable difference.

Other common irritants include strong cleaning products, scented candles, wood-burning fireplaces, and pet dander. You do not need to sterilize the house, but during an active cough, reducing airborne irritants can keep the airways from being doubly provoked. Running an air purifier with a HEPA filter in the child’s bedroom and keeping windows closed on high-pollen days are simple steps that can help.

When a Cough Needs More Than Home Remedies

Most coughs in children are caused by viral upper respiratory infections and resolve on their own within two to three weeks. But a cough that lasts longer than four weeks is classified as chronic and deserves a medical evaluation. In preschool-aged children, the most common causes of chronic cough include protracted bacterial bronchitis, airway malacia, foreign body aspiration, and post-infectious inflammation.² None of these will respond to honey or humidifiers, and some require specific treatment.

You should contact your child’s doctor sooner than four weeks if you notice any of the following alongside the cough:

• Breathing difficulty: fast breathing, visible rib retractions, flaring nostrils, or a bluish tint around the lips.
• High or persistent fever: especially if it spikes again after initially improving, which can signal a secondary bacterial infection.
• Wheezing: a whistling sound when breathing out, which may indicate asthma or bronchiolitis.
• Bloody mucus: any blood-streaked sputum warrants evaluation.
• Weight loss or poor feeding: a child who is coughing too much to eat or drink needs medical attention.

A clinical guideline for chronic cough management in children recommends a focused history, a chest X-ray, and spirometry for children over six as part of the workup, followed by treatment of whatever underlying condition is identified.²⁴

Habit Cough in Older Children

Occasionally, a child will keep coughing long after an infection has cleared, even though nothing is physically wrong with their lungs. This is sometimes called a habit cough or psychogenic cough. It tends to show up in school-age children and adolescents, is typically dry and repetitive, and characteristically disappears during sleep. It can last weeks or months and is genuinely distressing to the child and family.

Habit cough does not respond to cough medicine, honey, or any of the physical remedies discussed above. Behavioral approaches are the standard treatment: techniques like distraction, breathing exercises, and positive reinforcement help the child break the cough cycle. Speech therapy focused on breathing patterns and relaxation can also help when the habit involves vocal cord dysfunction. The prognosis is generally good once the pattern is recognized and addressed, but getting to that point often requires ruling out other causes first, which means a visit to the pediatrician is the right starting point.

Antihistamines and Allergy Medicines

Many parents wonder whether giving an antihistamine will quiet a child’s cough. For a typical viral cough, the answer is no. Clinical guidelines for children with chronic nonspecific cough recommend against the routine use of first-generation antihistamines, noting that the side effects (drowsiness, irritability, and in rare cases more serious reactions in very young children) outweigh the unproven benefits.²⁵ The exception is when the cough is tied to allergic rhinitis, where treating the underlying allergy with an appropriate antihistamine can reduce the postnasal drip driving the cough. If your child’s cough is seasonal, accompanied by itchy eyes and sneezing, and consistently worse around known allergens, an allergy evaluation may be more useful than another jar of honey.
