Not sure whether your child’s cough, wheezing, or breathing changes could be bronchiolitis? Learn the early symptoms of bronchiolitis, what to watch for in babies, newborns, and toddlers, and when to seek medical care.
Tell us whether you’re noticing fast breathing, wheezing, cough, feeding trouble, fever, or unusual sleepiness, and get personalized guidance on possible bronchiolitis symptoms and next steps.
Bronchiolitis is a common viral illness that affects the small airways in the lungs, especially in infants and young children. Early symptoms of bronchiolitis often start like a cold, with a runny nose, mild fever, and cough. As it progresses, some babies develop bronchiolitis cough and wheezing, faster breathing, chest pulling in with breaths, trouble feeding, or lower energy. Parents often search for how to tell if baby has bronchiolitis because the symptoms can change over a day or two.
Bronchiolitis in infants symptoms often begin with a stuffy or runny nose, mild fever, and cough before breathing symptoms become more noticeable.
A bronchiolitis cough and wheezing may sound like whistling, rattling, or crackling. Some babies also seem to breathe louder than usual.
Babies with bronchiolitis symptoms may feed less, tire quickly during feeds, seem fussier, or become unusually sleepy compared with their normal behavior.
Breathing that seems quicker than normal can be a sign the lungs are working harder. Parents may notice shorter pauses between breaths.
Look for ribs pulling in, belly breathing, flaring nostrils, or head bobbing in younger babies. These can suggest increased breathing effort.
In newborns and very young infants, bronchiolitis symptoms newborn parents should take seriously include pauses in breathing, bluish lips, or a weak cry with poor feeding.
Infants may show cough, wheezing, feeding trouble, and fast breathing. Because babies have smaller airways, symptoms can become noticeable quickly.
Newborns may not wheeze much at first. Instead, they may seem extra sleepy, feed poorly, breathe irregularly, or have fewer wet diapers.
Toddlers may have cough, wheezing, fever with cold symptoms, and lower activity. They may also say their chest hurts or resist eating and drinking.
Seek urgent medical care if your child is struggling to breathe, has lips or skin that look blue or gray, cannot stay awake, is not drinking enough, has signs of dehydration, or has pauses in breathing. Call your child’s clinician promptly if symptoms are worsening, your baby is under 12 weeks old with breathing concerns, or you are worried about bronchiolitis symptoms in a newborn. If you are unsure what your child’s symptoms mean, a symptom assessment can help you decide on the next step.
A cold usually causes runny nose, congestion, and mild cough. Bronchiolitis often starts that way but may progress to bronchiolitis breathing symptoms such as wheezing, faster breathing, chest pulling in, feeding difficulty, or unusual tiredness.
Early symptoms of bronchiolitis commonly include a runny or stuffy nose, mild fever, and cough. Over the next day or two, some children develop wheezing, noisier breathing, and more effort with breathing.
Yes. Bronchiolitis symptoms in newborns can be less obvious. Instead of clear wheezing, they may have poor feeding, sleepiness, pauses in breathing, or fewer wet diapers. Because newborns can get sicker faster, breathing concerns in this age group deserve prompt attention.
No. Bronchiolitis cough and wheezing are common, but not every baby wheezes. Some children mainly have cough, congestion, fast breathing, or trouble feeding.
Contact a clinician if your toddler has worsening cough, wheezing, fever with breathing trouble, poor drinking, low energy, or signs of hard breathing such as ribs pulling in or breathing much faster than usual.
If you’re trying to figure out whether your child’s cough, wheezing, feeding trouble, or breathing changes fit bronchiolitis, answer a few questions for a clear symptom assessment and next-step guidance.
