Should I Take My Baby to the Doctor for a Cold?

Colds In Babies Can Cause Serious Symptoms

You have probably arrived at this page because your baby has a bad cold, and you are not sure whether you should call a doctor. So I will start by saying that in my experience it is better to overreact than to wait too long. If after you have read this article you are still worried, make that call.

I am not a medical professional, but I am a parent whose daughter had bronchiolitis twice as a baby, and I know how rapidly it can take effect. My aim with writing this is not to alarm parents, but to encourage you to trust your parental instinct and get the help your baby needs. By sharing our daughter’s story, I hope you will see that even a seriously ill baby can recover.

The first time my daughter had bronchiolitis she did not have the classic symptoms but was very ill. This article will explain both the classic symptoms and other signs to watch out for.

What is bronchiolitis?

Bronchiolitis is a condition or complication that can occur during a viral illness. The bronchioles are small airways of the lungs that connect the main tubes (the bronchi) to the air sacs (alveoli.) In bronchiolitis, the bronchioles become inflamed and this restricts the flow of air in and out of the lungs.

Does having bronchiolitis mean my baby has asthma?

No, the two conditions are different. Some children who have had bronchiolitis do go on to develop asthma, but not all do. Our daughter often had asthma symptoms with a cold but at no other times. This is known as virally-triggered asthma.

If your baby has a cold and is having breathing difficulties, do not try to treat with her with asthma medication as this could make her worse.

What causes bronchiolitis?

It is most frequently caused by the respiratory syncytial virus (usually called RSV) but in around 25% of cases, another virus is the cause. The human rhinovirus is the next most common cause.

These illnesses are variations of the common cold so at first your baby will appear to have a bad cold. Most often bronchiolitis starts after a baby has had the cold for a few days.

Is it serious?

In the vast majority of cases it is not, but for some babies it can be very serious and may mean a lengthy stay in hospital. In extreme cases, it can be fatal.

At what time of year are babies most at risk?

In the Northern Hemisphere, most cases of bronchiolitis occur between October and March. (For the Southern Hemisphere those times would be April to September.) It was November both times my daughter contracted it, but her cousin caught bronchiolitis in June. So just because it is not the time of year for bronchiolitis, don’t assume your baby can’t have it. If she appears to you to be very ill she probably is.

Who gets bronchiolitis, and who is most at risk with it?

Bronchiolitis most commonly affects babies under one year old, particularly babies of 3 – 6 months. However, babies over one year can be affected. My daughter had bronchiolitis twice, and the second time she was over a year old.

Babies whose mothers smoked during pregnancy are more at risk of contracting severe bronchiolitis, as are babies who live in a smoky environment. Babies who have congenital heart disease or who were born prematurely are also more at risk. (My daughter was premature.)

Can anything prevent bronchiolitis?

Since smoking near a baby increases the risk, make sure your baby is not in a smoky environment.

Because the viruses that cause bronchiolitis are contagious, it is important to wash hands, avoid coughing near your baby if possible and try to avoid taking your baby into crowded places.

There is no vaccine against the illnesses that cause bronchiolitis, but if your baby is considered at risk he may be offered an injection containing antibodies to the RSV virus, which is the most common cause of bronchiolitis. This injection is given at monthly intervals during the RSV season. Because our daughter tested negative for RSV she was given this shot throughout the winter months.

When to call the doctor for your baby’s cold

Some symptoms of bronchiolitis that professionals advise parents to look out for:

  1. A dry cough.
  2. Fever.
  3. Having difficulty feeding or not feeding at all.
  4. Nostrils flare as the baby tries to breathe more deeply.
  5. Rapid breathing (in babies under one-year-old this is over 6o breaths a minute.)
  6. Wheezing.
  7. The baby’s diaphragm (just below the ribs) sinks in as she tries to breathe.
  8. Blue-tinged lips or skin.
  9. Your baby stops breathing for up to 10 seconds a time – the name for this is apnoea.

If your baby has the first 2 symptoms only, they probably just have a cold. If they have several of the first 6 symptoms, you should call a doctor. If your baby has a cold and has either of the last 2 symptoms, even if they don’t have the others, get to a hospital as quickly as possible or call an ambulance.

The video below is the best out of several I watched that explain the symptoms of bronchiolitis and when to see a doctor.

Other Signs Your Baby May Have More Than Just A Cold:

The first time our daughter had bronchiolitis; to begin with, her only symptom was sleeping a little longer than usual. Since she’d had a cold for several days and hadn’t slept well, so at first, we thought she might just need more rest. She wasn’t fevered, her breathing wasn’t fast, she had no wheezing sound and had fed reasonably well.

However, to me, something seemed wrong. She wasn’t blue-tinged, but she looked slightly grey. Like many mothers, I thought perhaps I was over-reacting and since my husband wasn’t worried at that stage I didn’t call a doctor.

Since my daughter was born very prematurely, it was important for her not to go too long without a feed, so eventually, I woke her. She fed well, so again I thought I had been overreacting. Then she stopped breathing, and her eyes rolled so that only the whites were visible. Before we had time to resuscitate her she began breathing again.

Trust Your Parental Instincts.

Even though our daughter began breathing again without assistance, we took her to hospital. At first, the staff thought she seemed fine, this soon proved to be far from the case.

When to go to the doctor or hospital: Quick checklist of symptoms

But trust your own instinct. Even if several of the first symptoms are not present, but your baby seems very unwell: call the doctor.

Symptom Call the Doctor or Take Baby to Hospital

Runny nose


Dry cough




Having diffiulty feeding


Very listless and sleepy


Nostrils flare when breathing


Rapid breathing




Diagphram sinks in when breathing


Blue tinged lips or skin


Stops breathing for up to 10 seconds


What Will Happen If You Take Your Baby To A Doctor

Your doctor will check your baby’s lungs with a stethoscope for signs of infection such as wheezing or crackling and will assess his overall state of health. If your doctor thinks your baby can stay at home, your doctor will advise you on how to make your baby more comfortable until the bronchiolitis has passed. Your doctor might prescribe a bronchodilator inhaler. Bronchodilators relax muscles and open airways but are not always effective for bronchiolitis. Some doctors might prescribe a nebulizer. (See below for more information.)

If your baby is experiencing a lot of difficulty breathing, your doctor is likely to refer him to hospital.

What Will Happen If You Take Your Baby To Hospital?

  • Almost certainly the first thing that will happen is a doctor will check your baby’s lungs with a stethoscope.
  • The oxygen level in your baby’s blood will be checked. This is done non-invasively and is not painful or harmful. A probe will be attached to your baby’s foot and will look similar to the one in the photograph on the right.
  • If your baby’s oxygen levels are good, he may not need any treatment, but if he already has severe difficulty breathing, some treatment will be necessary.
  • Your baby’s chest may be x-rayed.

Treatments Your Baby May Receive

You may be frightened by thoughts about the treatment your baby will receive. Below are descriptions of some treatments, ranging from those for least serious to most serious. The accompanying photographs are of my daughter when she was still very small and were not taken during bronchiolitis, although in the photograph with the ventilator she was ill.


Giving your baby medication through nebulizer is a common treatment for bronchiolitis. A nebulizer is a machine that creates a fine mist containing droplets of the medicine. This helps to open the airways. You can watch how a nebulizer works in the video below. The second time my daughter was in hospital for bronchiolitis she was given medication through a nebulizer.

If your baby does not need oxygen you may be given a nebulizer to use at home. This will depend on the policy of your hospital.

This video shows how to use a nebulizer

A baby on oxygen

This baby receives oxygen through nasal prongs taped to her face. On admittance to hospital it is more likely a mask will be used instead.

Often, the first treatment a baby will be given is oxygen. There are several ways to administer oxygen: using a mask, by oxygen prongs or by placing an oxygen headbox over the baby’s head. In the first instance, your baby’s oxygen will most likely be administered by mask.

You can see a baby with oxygen prongs in the photo below.


If your baby is very ill and does not respond to oxygen alone, the next treatment likely to be used is a CPAP machine. CPAP stands for continuous positive airway pressure: it uses air pressure to stop airways from collapsing. This means your baby does not have to work so hard to breathe.

The photograph below is of a baby on CPAP. As you can see it is still possible to hold your baby.

This photo shows a very premature baby on CPAP.

If your baby is still not able to breathe with a CPAP machine, then she will be placed on a ventilator. This does the breathing for the baby. If your baby needs a ventilator she will be transferred to an intensive care unit and may be sedated. It can be very frightening to see your baby on a ventilator, but even if this happens she is likely to recover well. That first time our daughter had bronchiolitis she needed a ventilator for 9 days.

Although in the photograph below I am holding my daughter, when she was severely ill with bronchiolitis this was not possible. Like her, if your baby needs ventilating, she is likely to be in an intensive care cot or crib and will be monitored carefully. She will also need to be fed through a tube or by given a drip.

Sometimes nurses also needed to remove the excess mucus from my daughter's lungs when she was very ill. This meant suctioning off the mucus by use of a long tube. To do that they had to take her off the ventilator, and so they also performed a procedure known as "hand bagging" that means manually ventilating the lungs. Only seriously ill babies will require this treatment.

Bronchiolitis Can Escalate Rapidly

Sometimes the condition of babies with bronchiolitis can deteriorate very rapidly and this is what happened to our daughter. When we brought her to the hospital she was breathing unaided, and her color looked fine, so the staff were not unduly concerned. When a nurse checked oxygen saturation, she at first thought the monitor must be wrong because the level was so low. Our daughter was then given oxygen and her saturation increased. But by the time doctors had taken a chest x-ray, she needed a CPAP machine and about an hour later was on the ventilator and 80% oxygen. (Air is 21% oxygen.) Even so, after 9 days in intensive care, she was well enough to return to a children’s ward and after 4 weeks in hospital she came home.

The second time our daughter had bronchiolitis was a year later, and after a night receiving medication through a nebulizer, by morning she was bouncing in her hospital crib.

Amanda, I am glad this was useful for you. Thanks for letting me know, especially since you are having a hard time right now. I wish you and your baby all the very best.

amanda durley on December 19, 2013:

Thank you for this. I am sat next to my 7 week old daughter currently in a cpap machine and I was struggling

Yvonne Spence (author) from UK on October 18, 2012:

Hi mattgottung, it is very scary for the parent you are right. From what I read it seems that in the UK our definition of bronchiolitis isn't as broad as elsewhere and here it's mainly used for the more severe symptoms. Thanks for your kind comment and glad you found this info great!

Matthew Gottung from New England, United States on October 18, 2012:

Bronchiolitis is relativly common in children/babies....but nonetheless VERY scary for a parent, and potentially dangerous for baby. Thank you very much Melovy, great content and great info.

Yvonne Spence (author) from UK on September 30, 2012:

Marcy, it's quite likely you did see it and not realise what it was. I had never heard of bronchiolitis until my daughter caught it even though she'd previously spent 3 months in hospital.

Thanks for your comment.

Yvonne Spence (author) from UK on September 30, 2012:

kimberlie33, I was very scared at the time, but fortunately it all turned out well! Bronchiolitis is more common than many people realise, and since it's coming up to the season it seems a good idea to let people know the symptoms. I hope your daughter is keeping well now, and thanks for your comment.

Marcy Goodfleisch from Planet Earth on September 26, 2012:

I'm wondering if I have seen this in babies but not realized it at the time. This is so informative and helpful - thanks for explaining this condition!

Voted up!

Kimberlie Kacan from Brooklyn, NY on September 26, 2012:

Thank you for sharing such an intense story. You must have been so scared! It is very important for parents to know these symptoms, especially with a new baby. My daughter caught bronchiolitis when she was about 5 or 6 months old, and you are right, the effects can happen very quickly!

Mary Craig from New York on September 25, 2012:

Very interesting and informative. It is always sad to have to learn these things the hard way. I like how you described what to expect at the is always frightening when you have to take a baby or small child to the hospital, especially with breathing difficulty.

Voted up, useful, and interesting.

Yvonne Spence (author) from UK on September 25, 2012:

Hi Ruchira, glad you found this useful and thanks for your comment and the vote up!

Yvonne Spence (author) from UK on September 25, 2012:

Thank you Lipnancy, I hope you are right and it does help many parents.

Yvonne Spence (author) from UK on September 25, 2012:

Yes, midget38, this is surprisingly common and yet many people don't know about it. I hope that it will be useful to others and thanks for your comment and for sharing.

Ruchira from United States on September 25, 2012:

Well done with this indepth information about bronchitis. With cold season coming in, there are times when parents cannot differentiate between an asthma attach or the brochitis.

voted up as useful.

Nancy Yager from Hamburg, New York on September 25, 2012:

This is a very intensive guide for a very serious situation. I am sure this will help many parents.

Michelle Liew from Singapore on September 25, 2012:

Useful guide, Yvonne. Illnesses like these endanger infants' lives all the time. and we should be aware of them and not wait before they strike. Thanks for bringing it to our attention. Votes up and shared.

Yvonne Spence (author) from UK on September 25, 2012:

Mhatter99, thanks for reading!

Martin Kloess from San Francisco on September 24, 2012:

Thank you for bringing this to our attention.

Yvonne Spence (author) from UK on September 24, 2012:

Hi Nettlemere, You're right it was scary how fast our daughter deteriorated. We were fortunate that the hospital where she had been in her last few weeks as a premature baby was nearby and had a policy that we could take her straight back to the special baby unit. She ended up in Intensive care in a hospital an hour away, but that care definitely did the trick!

I'm very pleased that you found this guide clear and thanks for your comment.

Yvonne Spence (author) from UK on September 24, 2012:

RealHousewife, it can be very terrifying when you think your baby might die. I had that fear too. Good for you that you persisted and got your daughter the attention she needed.

Thanks for your comment!

Nettlemere from Burnley, Lancashire, UK on September 24, 2012:

This is a very useful and clear guide about what to look out for and what treatment might be necessary. It's scary how fast your daughter deteriorated but reassuring to know that the hospital treatment did the trick and that not all bronchiolitis cases require it.

Kelly Umphenour from St. Louis, MO on September 24, 2012:

Yeah Melovy - I do wish I'd had this info 24 years ago!! Yes my oldest had this and it got pretty scary! My case was different in that my doctor was ignoring my fear. He kept telling me "it's just a cold" he was SUCH a jerk he wouldn't even log my appointment. I just took her - 3 days in a row!! Finally (well she looked like she was gonna die to me) he tested her for something...never told me what but immediately they admitted her, quarantined her and IV fluids for a few days.

Great hub!!
