Bronchiolitis Home Care for Parents: Nasal Saline, Gentle Suction and Smaller, Frequent Feeds

It is 2 a.m. and you are standing over the crib counting. Not minutes, but breaths. Your five-month-old has had a runny nose for three days, and tonight the breathing has a new sound to it, a wet rattle with a faint whistle at the end. She fed for four minutes, pulled off, breathed hard, and fell asleep hungry. You are not sure whether this is the moment to drive somewhere or the moment to wipe her nose and wait.

That uncertainty is the real work of bronchiolitis home care, and it deserves better than a photocopied leaflet. Most babies with bronchiolitis never need a hospital. What they need is a parent who understands why the nose matters more than the chest, why a short feed is not a failure, and which handful of signs should end the waiting.

This guide walks through the evidence behind the three things pediatric teams keep coming back to: saline, suction and smaller feeds. It also says plainly what does not help, because a tired parent should not spend the night on remedies that the studies never supported.

What is bronchiolitis and what is actually happening in a baby's chest?

Bronchiolitis is a viral infection of the bronchioles, the smallest branching airways deep in the lungs, each one narrower than a strand of spaghetti. A virus, most often respiratory syncytial virus (RSV), settles into the lining of those tubes. The lining swells, sheds cells and produces sticky mucus. Air still gets in, but it has to squeeze past the narrowing, which is where the wheeze and crackle come from (Mayo Clinic).

The reason this matters so much more in infants than in adults comes down to simple geometry. A tiny airway loses a far larger share of its opening to the same thickness of swelling than a wide one does. Picture a drinking straw and a garden hose each coated inside with the same thin film: the straw is almost blocked, the hose barely notices. A baby’s bronchioles are the straw.

Bronchiolitis is often confused with bronchitis, which is inflammation of the larger central airways and mostly a problem of older children and adults. Both involve cough and mucus, but bronchiolitis sits further down the airway tree and targets the youngest patients.

One more piece of anatomy explains why home care focuses on the nose. Babies under about six months breathe mainly through the nose, and feeding depends on it: a bottle or breast occupies the mouth, so a blocked nose forces a baby to choose between breathing and swallowing. Clearing that nose does not touch the virus in the lungs, but it removes a second obstacle on top of the first, and that is why clinicians rate it so highly (Cleveland Clinic).

There is no medicine that shortens the infection itself. The body clears it; our job is to make the waiting safer and more comfortable.

Bronchiolitis in babies: who is usually cared for at home, and who is watched more closely?

The large majority of babies with bronchiolitis are looked after at home. The NHS describes most cases as mild, clearing within 2–3 weeks without treatment beyond comfort and fluids. The illness is most common in babies between three and six months old, although it can affect children up to two years (NHS).

A smaller group needs a closer eye from the start. Clinical guidance lists babies born prematurely, those with a chronic lung condition, a congenital heart condition or a weakened immune system as higher risk for a more serious course (NHS, Mayo Clinic). Very young infants, in the first weeks of life, are also treated with extra caution because their reserves are small and feeding can fall off quickly. If your baby fits any of these descriptions, the threshold for a same-day review is lower, and your care team may have already told you so.

Hospital care, when it is needed, is still supportive rather than curative. In the United States, the CDC estimates that 58,000–80,000 children under five are hospitalized with RSV each year, most of them for one of three reasons: oxygen levels that have dropped, feeding that has fallen below what is safe, or breathing that has become so effortful that the baby is tiring (CDC). Oxygen through small nasal prongs, fluids through a tube or a drip, and watchful nursing cover most of what a ward provides.

So the honest framing is not home versus hospital as success versus failure. It is a question of whether a particular baby, on a particular day, can breathe, feed and stay hydrated without help. That judgment belongs with your pediatric team, and it can change from one day to the next during the peak of the illness.

Is bronchiolitis contagious, and how do I protect the rest of the household?

Yes. The viruses behind bronchiolitis spread the way cold viruses do: through droplets when someone coughs or sneezes, and through hands that touch a contaminated surface and then a face. RSV in particular can survive for many hours on hard surfaces such as tables, crib rails and toys, and for shorter periods on soft surfaces and skin (CDC). An older sibling with what looks like an ordinary cold is the most common source of an infant’s bronchiolitis.

Nearly every child has had an RSV infection by their second birthday, so complete avoidance is unrealistic (CDC). What you can do is reduce the dose and delay the timing, which matters most when the baby is under six months.

Practical steps with reasonable evidence behind them:

• Wash hands with soap for at least 20 seconds before handling the baby, and ask visitors to do the same (CDC).
• Keep anyone with cold symptoms from kissing the baby’s face or hands.
• Wipe high-touch surfaces and shared toys daily during the illness.
• Keep the baby out of daycare until they are well enough to feed and breathe comfortably (NHS).
• Keep the home smoke-free; exposure to tobacco smoke raises both the risk and the severity of bronchiolitis (Mayo Clinic).

A baby with bronchiolitis can pass the virus on for several days, and infants sometimes shed virus longer than older children. There is no fixed isolation period in consumer guidance; the NHS advice is to keep a child away from nursery until they are feeling better and no longer unwell with the illness.

For adults in the house, the same virus usually causes nothing more than a cold. The exception is older relatives or anyone with heart or lung disease, for whom RSV can be more serious; it is reasonable to postpone grandparent visits until the baby is recovering (CDC).

How long does bronchiolitis last? The typical timeline, honestly described

Bronchiolitis follows a fairly predictable arc, and knowing the shape of it is one of the most calming things a parent can learn. The NHS describes symptoms as usually worst between days three and five, with most children recovering within 2–3 weeks. A cough can linger for a few weeks after everything else has settled (NHS).

The first two or three days usually look like a cold: runny nose, mild cough, perhaps a low fever. Then the infection reaches the small airways, and the breathing changes. Faster breaths, a wheeze, a cough that sounds wetter, and feeds that get shorter and more effortful. This is the stretch most parents find frightening, and it is also the window in which clinicians most want to hear from you if feeding or breathing slips.

After the peak, improvement tends to be gradual rather than sudden. Breathing eases first, feeding recovers next, and the cough is the last to go. A baby who is drinking well and sleeping better but still coughing at week two is following the expected path, not relapsing (Mayo Clinic).

Two caveats keep this honest. First, these are typical ranges drawn from guidance, not a timetable for your baby; premature infants and those with underlying conditions can take longer. Second, a second virus can arrive before the first has cleared, which is why a baby who seemed to be mending can dip again. That second dip is not usually a sign that something was missed, but it is a reason to check in with your doctor rather than assume.

Write the start date on the fridge. When you are tired, knowing you are on day four rather than day nine changes how you read a rough night.

Nasal saline: why a few drops of salt water do so much

Nasal saline is sterile salt water in the same concentration as the body’s own fluids, sold as drops or a fine spray made for infants. It does nothing to the virus. What it does is change the physics of the mucus. Dried, thick secretions cling to the nasal lining like glue; a few drops of saline thin them, loosen the crust and allow the baby to sneeze, swallow or be suctioned clear. Pediatric sources consistently list saline drops as a first-line comfort measure for bronchiolitis (Cleveland Clinic, Mayo Clinic).

Technique matters more than the product. A method most clinics teach:

• Lay the baby on their back with the head tilted slightly back, or hold them semi-upright on your lap with the head supported.
• Place one or two drops in each nostril, following the instructions on the product label for infants.
• Wait 30–60 seconds. The baby will object; that is normal.
• Let them sneeze, or follow with gentle suction if the nose is still blocked.

Timing is the part parents most often miss. Saline given five minutes before a feed and again before sleep delivers the biggest payoff, because those are the moments a blocked nose costs the most. Random use through the day adds irritation without much benefit.

Saline alone is often enough. Many babies clear their own nose with a sneeze once the mucus is loosened, and skipping the suction step on those occasions is a kindness, not a lapse.

Avoid homemade salt solutions for infants; the concentration is hard to control and too much salt irritates the lining. Use a product made for babies and discard it according to the label once opened. If the nostrils look raw, ask your pediatric team whether a thin layer of a bland barrier ointment around the outside of the nose is appropriate.

Gentle suction: how to use a bulb syringe without making things worse

A bulb syringe is a soft rubber pear with a tapered tip; squeezed before insertion and released inside the nostril, it draws mucus into the bulb. Suction devices operated by a parent’s mouth through a filter work on the same principle. Both are standard tools in bronchiolitis home care and are recommended alongside saline by major pediatric sources (Cleveland Clinic, Mayo Clinic).

The common mistake is enthusiasm. The nasal lining is delicate and already inflamed; repeated or forceful suction causes swelling that narrows the passage further and can cause small bleeds. The goal is a clear nose for the next feed, not a dry one.

A gentle routine:

• Give saline first and wait.
• Squeeze the bulb fully before it goes near the nose.
• Insert the tip just inside the nostril, aiming slightly toward the outer corner of the eye rather than straight back.
• Release the bulb slowly, withdraw, and squeeze the contents onto a tissue.
• Repeat on the other side if needed, then stop.

Most teams suggest suctioning before feeds and before sleep, and otherwise leaving the nose alone. A rough guide many clinicians give is a small number of sessions per day rather than suctioning every time the baby sounds congested; the sound of mucus is not itself harmful.

Cleaning is the unglamorous part. Rinse the bulb with warm soapy water after every use, squeeze it out several times, and let it dry tip-down. A damp bulb grows mould inside where you cannot see it.

Finally, listen to your baby after suction. If the breathing eases and the next feed goes better, you are doing it right. If the baby stays distressed despite a clear nose, the problem is lower in the chest, and that is a conversation for your doctor rather than a reason for more suction.

Smaller, frequent feeds: the hydration strategy that keeps babies out of hospital

Feeding is the hinge on which home care turns. Babies with bronchiolitis take fewer and shorter feeds because breathing fast through a congested nose while swallowing is exhausting. Poor feeding, more than the wheeze itself, is one of the most common reasons an infant is admitted (NHS). The counter-strategy is simple: offer less, more often.

A baby who normally takes a full feed every four hours might manage half that amount every two hours. The daily total can stay close to normal while each individual effort stays within what the baby can tolerate. Breastfed babies can be offered the breast more frequently; bottle-fed babies get smaller volumes in more sittings. Clear the nose with saline and gentle suction a few minutes before each attempt, hold the baby a little more upright than usual, and allow pauses.

Do not dilute formula or add water to feeds in an infant under six months; it does not improve hydration and can upset salt balance. Do not introduce new solids during the illness. Breast milk or the usual formula is the right fluid (NHS).

The measure that matters is output. The NHS advises contacting a doctor if a baby has taken less than half their usual amount during the last two or three feeds, or has had a dry diaper for 12 hours or more. Other signs of dehydration include a sunken soft spot on the head, few or no tears, a dry mouth and unusual sleepiness.

Write feeds down. At 3 a.m. memory is unreliable, and your pediatric team will make a far better decision with a scrap of paper that says what went in and how many diapers came out. That record is often the single most useful thing a parent brings to an appointment.

Comfort, sleep and the air in the room: what helps and what the evidence does not support

Beyond the nose and the feeds, comfort is about position, rest and clean air, and here the evidence separates sensible habits from popular ones.

Holding a congested baby upright against your chest helps mucus drain and often settles breathing. That is fine while you are awake and holding them. Sleep is different. Safe sleep guidance from the NHS and from pediatric bodies is unchanged by bronchiolitis: on the back, on a firm flat surface, with no pillows, wedges or raised mattress ends. Propping an infant to sleep raises the risk of sliding into a position that blocks the airway, and the evidence that elevation improves bronchiolitis is lacking. If a baby cannot sleep flat because of breathing, that is a reason to seek care, not to improvise.

Steam and humidifiers are the question every parent asks. A warm, steamy bathroom feels helpful and is probably harmless for a few minutes, but controlled studies have not shown that humidified air shortens or eases bronchiolitis, and mainstream guidance no longer recommends it as treatment (Mayo Clinic). A cool-mist humidifier may make a dry room more comfortable; if you use one, clean it daily, because a dirty tank aerosolizes mould and bacteria. Never use hot-water vaporizers near an infant.

Smoke is the one air-quality factor with firm evidence. Exposure to tobacco smoke, including smoke on clothing and hair, increases the risk and severity of bronchiolitis (Mayo Clinic). The home should be smoke-free throughout the illness and ideally afterwards.

Rest is treatment. A baby fighting a respiratory infection burns energy on every breath. Shorter outings, quieter days and more holding are not indulgence; they conserve what the baby needs for breathing and feeding.

Can bronchiolitis be treated with an inhaler, antibiotics or cough medicine?

Usually not, and understanding why spares a lot of frustration at the pharmacy counter.

Antibiotics kill bacteria. Bronchiolitis is viral, so antibiotics have no target and are not prescribed unless a clinician finds a separate bacterial infection such as an ear infection (NHS, Mayo Clinic). Asking for them is understandable; receiving them would add side effects without benefit.

Inhalers are the harder conversation. Bronchodilators, the class of medicine that relaxes muscle around the airways and opens them in asthma, are not routinely recommended in bronchiolitis. The narrowing in bronchiolitis comes mainly from swelling and mucus rather than muscle spasm, so the mechanism does not match the problem, and trials have shown no consistent improvement in how the illness runs (NHS). A clinician may occasionally try one in a specific child, particularly an older infant with a strong family history of asthma, and will then judge whether it helped. That is a decision for the prescriber, not a reason to use a sibling’s inhaler at home.

Corticosteroids, which reduce inflammation, are likewise not routinely used for bronchiolitis in infants because studies have not shown meaningful benefit (NHS, Mayo Clinic).

Over-the-counter cough and cold medicines should not be given to children under six; they have not been shown to help and carry risks for young children (NHS). Honey is sometimes suggested for cough but must never be given to a baby under one year because of the risk of infant botulism.

Fever itself is part of the body’s response. Fever-reducing medicines in the acetaminophen or ibuprofen classes exist for comfort, but whether one is appropriate depends on the baby’s age and weight. Your pediatric team or pharmacist can tell you whether and how to use one; this article deliberately does not.

Bronchiolitis home care at a glance: what helps, what does not, what is unproven

Parents often ask for home remedies for wheezing, and the plain answer is that nothing applied at home opens a baby’s small airways. What home care can do is remove obstacles upstream, keep the baby hydrated and buy time for the immune system. The table sorts the common suggestions by what the evidence actually shows.

Measure	What it does	Evidence position
Nasal saline before feeds and sleep	Thins mucus so the baby can breathe through the nose while feeding	Recommended comfort measure (Cleveland Clinic, Mayo Clinic)
Gentle bulb suction, a few times daily	Clears loosened mucus from the nostrils	Recommended; overuse causes swelling
Smaller, more frequent feeds	Maintains hydration when each feed is tiring	Core of home care (NHS)
Upright holding while awake	Aids drainage, eases breathing	Reasonable; sleep must still be flat on the back
Smoke-free home	Reduces airway irritation and severity	Supported by evidence (Mayo Clinic)
Humidifier or steamy bathroom	May feel soothing	Not shown to change the illness; keep devices clean
Bronchodilator inhalers	Relax airway muscle	Not routinely recommended; mechanism mismatch (NHS)
Antibiotics	Kill bacteria	No effect on viral bronchiolitis (NHS)
Cough and cold medicines	Suppress cough or dry secretions	Not for children under six (NHS)
Honey	Soothes throat in older children	Never under one year (botulism risk)
Chest rubs, essential oils, herbal syrups	Various claims	No evidence of benefit; some irritate infant airways

The pattern in the table is worth stating: the measures with the best support are the plainest ones, and the measures with the strongest marketing are the ones the evidence does not back. When a wheeze is loud enough to worry you, the right move is a call to your doctor, not a trip to the remedy aisle.

What the next days and weeks usually look like at home

Day by day, bronchiolitis home care changes shape, and it helps to know what each stretch tends to ask of you.

Days one to three usually feel like a cold. Saline before feeds, a smoke-free room and more frequent offers of milk are enough. This is the time to start the feeding and diaper log and to check that your pediatric team’s phone number is somewhere you can find it at night.

Days three to five are the peak for most babies (NHS). Breathing is faster, the cough is wetter and feeds are shorter. Expect to be clearing the nose before every feed and to be feeding more often than feels normal. Expect broken sleep. This is also the stretch when most families who need a review end up calling, and when watching the breathing pattern matters most. Look at the baby undressed to the waist in good light once or twice a day: are the ribs pulling in with each breath, is the belly working hard, is the baby too breathless to feed? Those observations are what a clinician will ask about.

Days six to ten bring gradual easing. Feeds lengthen first, often before the cough changes. Nights improve unevenly; a good night followed by a poor one is common.

Weeks two and three are the long tail. Most children are back to themselves by the end of this period, but a cough can persist for a few more weeks (NHS). A baby who is feeding well, breathing comfortably and cheerful between coughs does not need the cough to be gone before returning to normal routines; a return to daycare when the baby is feeling better and feeding normally is reasonable (NHS).

Keep the saline and bulb to hand afterwards. Bronchiolitis can recur with a different virus, and the second time you will know the drill.

What people often get wrong about bronchiolitis

Some of the most common beliefs about bronchiolitis would be harmless if they were only wrong. A few of them change what parents do at 3 a.m., which is why they are worth correcting.

A wheezing baby has asthma. Wheeze in an infant with a cold is most often bronchiolitis. Asthma is a diagnosis made over time, usually in older children with repeated episodes and other features. Children who had severe bronchiolitis do have a somewhat higher chance of later wheezing, but the evidence shows association, not proof that one causes the other (Mayo Clinic). One illness is not a diagnosis.

Green mucus means antibiotics. Mucus turns yellow or green because immune cells pour into it during any respiratory infection, viral or bacterial. Color alone does not indicate a bacterial infection.

The fever number is the main thing to watch. In bronchiolitis, breathing effort and feeding are far better guides to severity than the thermometer. A baby with a modest temperature who cannot feed is in more trouble than a baby with a higher one who is drinking well.

More suction is better. Repeated suction swells the nasal lining and narrows the passage. Clear before feeds and sleep, then stop.

Propping the mattress helps them breathe at night. There is no evidence of benefit, and it works against safe-sleep guidance. Flat on the back remains the rule.

A steamy bathroom is treatment. It is comfort at most; studies have not shown it changes the illness (Mayo Clinic).

Once a baby has had RSV, they are immune. Protection after infection is partial and short-lived. Repeat infections are common, although later ones are usually milder (CDC).

Hospital means something went wrong at home. It usually means a baby needed oxygen or feeding support that cannot be given anywhere else. Good home care includes recognizing that moment.

Questions to ask your care team about bronchiolitis home care

A short appointment goes further when you arrive with specific questions. These are the ones that tend to change what parents do afterwards.

• Given my baby’s age and history, what is the earliest sign that should make me call rather than wait?
• How many wet diapers per day would you expect for a baby this age, and at what point does fewer become a concern?
• Roughly how often should I use saline and suction, and is there a point where I am doing too much?
• Should I change how I breastfeed or bottle-feed during the illness, and how small can a feed be while still counting?
• Is a fever-reducing medicine appropriate for my baby’s age, and if so, how would you like me to use it?
• Are there any reasons, in my child’s case, that you would consider an inhaler or other medicine, and how would we know whether it helped?
• Which day of the illness are we on, and when would you expect the worst to pass?
• Who do I call overnight and at weekends, and what should I say so the right person hears it quickly?
• When can my baby return to daycare, and what should I tell the staff?
• Are there vaccines or preventive options for RSV that are relevant to my baby, to me as a pregnant or breastfeeding parent, or to older relatives, and when would we discuss them?

Write the answers down in the same notebook as the feeding log. Guidance given in a calm clinic room is hard to recall during a frightening night, and a clinician’s own words about your own child carry more weight than any article, including this one.

If English is not your first language, or if a relative will be doing the night shifts, ask for the key thresholds written in plain terms. The care plan only works if everyone looking after the baby can follow it.

When to call your doctor: red-flag signs in bronchiolitis

Most of this article is about patience. This section is about the limits of patience, and it is the one to read twice.

Call emergency services or go to the nearest emergency department immediately if your baby:

• has pauses in breathing, or breathing that is very fast, grunting or so labored that you can see the skin pulling in between or under the ribs and at the base of the neck with every breath
• has lips, tongue or gums that look blue, grey or pale
• is floppy, unusually drowsy, or hard to wake and keep awake
• is too breathless to feed or to cry
• is under three months old with a fever, or has a fever that you cannot explain and is working hard to breathe (NHS, Mayo Clinic)

Contact your pediatric team the same day, including out of hours, if your baby:

• has taken less than half their usual amount during the last two or three feeds, or has had a dry diaper for 12 hours or more (NHS)
• has breathing that seems faster or harder than earlier in the day, even if feeds are holding up
• has a persistent fever, or seems more irritable or more exhausted than the illness alone would explain
• was born prematurely or has a heart, lung or immune condition and seems to be getting worse rather than holding steady
• is not improving after the expected peak, or improves and then clearly worsens again

Trust the instinct that something is different. Parents are usually the first to notice a change in color, effort or alertness, and clinicians would far rather see a baby who turns out to be fine than hear about one who was watched too long. No sign in this list requires you to be certain; it requires you to pick up the phone. Every decision about whether home care continues, and about any medicine or oxygen, rests with the treating team, and they can only make it if they hear from you.

Frequently asked questions

Is bronchiolitis contagious to other children and adults?

Yes. The viruses that cause bronchiolitis, most often RSV, spread through coughs, sneezes and hands that touch contaminated surfaces, where the virus can survive for many hours. Older children and adults usually get only a cold from the same virus, but infants, older adults and people with heart or lung disease can become more unwell. Handwashing, keeping sick siblings’ faces away from the baby and staying home from daycare until recovered all reduce spread (CDC, NHS).

How is bronchiolitis treated in adults?

Classic bronchiolitis is essentially an infant illness; the same viruses in adults usually cause a cold or, in older or high-risk adults, a chest infection managed with rest, fluids and medical review if breathing is affected. A different, rare condition called bronchiolitis obliterans, in which the small airways scar, occurs in adults after certain exposures or transplants and is managed by specialists. Any adult with a persistent wheeze or breathlessness should be assessed rather than assume a childhood diagnosis applies.

What are some home remedies for wheezing in a baby with bronchiolitis?

Nothing applied at home opens a baby’s small airways, so the honest answer is to work upstream: nasal saline and gentle suction before feeds, smaller and more frequent feeds, upright holding while awake and a smoke-free room. Steam, humidifiers, chest rubs and herbal syrups have not been shown to change the illness, and some irritate infant airways. A wheeze loud enough to worry you, or one with fast or labored breathing, is a reason to call your doctor (Mayo Clinic).

Can bronchiolitis be treated with an inhaler?

Not routinely. Inhaled bronchodilators relax muscle around the airways, which is the problem in asthma, but in bronchiolitis the narrowing comes mainly from swelling and mucus, so trials have shown no consistent benefit (NHS). A clinician may occasionally trial one in a particular child and then judge whether it helped. Never use a sibling’s inhaler on a baby; the decision belongs with the prescriber who has examined your child.

How long does bronchiolitis last in babies?

Most babies are at their worst between days three and five and recover within 2–3 weeks, with the cough often the last symptom to settle and sometimes lasting a few weeks longer (NHS). Premature babies and those with heart, lung or immune conditions can take longer. A baby who feeds well and breathes comfortably but still coughs at week two is following the expected course rather than relapsing.

What does RSV bronchiolitis treatment at home actually involve day to day?

It is supportive care while the virus runs its course: saline drops and gentle bulb suction a few minutes before feeds and sleep, smaller feeds offered more often, upright holding while awake, safe flat sleep on the back, a smoke-free home and a written log of feeds and wet diapers. There is no medicine that shortens RSV bronchiolitis. The daily job is keeping the baby hydrated and comfortable and recognizing the signs that mean a clinician should look.

How often can I use nasal saline and suction on my baby?

Most pediatric teams suggest saline and gentle suction before feeds and before sleep, which usually works out to a small number of sessions a day, and otherwise leaving the nose alone. The nasal lining is already inflamed, and frequent or forceful suction swells it further and can cause small bleeds. Saline alone often triggers a clearing sneeze, so suction is not always needed. Ask your care team for a routine suited to your baby.

Is a humidifier or steamy bathroom helpful for bronchiolitis?

It may feel soothing, but studies have not shown that humidified air shortens or eases bronchiolitis, and mainstream guidance no longer recommends it as treatment (Mayo Clinic). A cool-mist humidifier can make a dry room more comfortable if it is cleaned daily, since a dirty tank sprays mould and bacteria into the air. Hot-water vaporizers should not be used near infants. Steam is comfort at best, never a substitute for calling about labored breathing.

What is the difference between bronchiolitis and bronchitis?

Bronchiolitis is inflammation of the bronchioles, the smallest airways deep in the lungs, and mostly affects babies under two, often causing wheeze and feeding difficulty. Bronchitis is inflammation of the larger central airways and is mainly seen in older children and adults, with cough and mucus as the leading features. Both are usually viral and neither needs antibiotics unless a bacterial infection is found, but the age group, location and risks differ.

Does bronchiolitis in babies lead to asthma later on?

Children who had severe bronchiolitis as infants do have a somewhat higher chance of recurrent wheezing in early childhood, but the evidence shows an association rather than proof that one causes the other; it may be that children already prone to reactive airways get sicker with the virus (Mayo Clinic). Most babies who have bronchiolitis do not go on to develop asthma. A single episode is not a diagnosis, and any later wheeze should be assessed on its own.
