A runny nose, a few coughs and a stuffy nose can be unsettling when they happen to a baby. Since babies cannot explain what is bothering them, even a mild baby cold and cough can leave parents wondering what they should do.
The good news is that most common colds in children are caused by viruses and usually improve with time and supportive care. Antibiotics do not treat viral colds.
For parents, the focus is usually simple: help the baby breathe comfortably, continue appropriate feeds, allow plenty of rest and keep an eye out for symptoms that need medical attention.
What Causes a Baby Cold and Cough?
A common cold is usually caused by a respiratory virus. Babies and young children can catch these infections easily because they are still developing immunity and are often exposed to other children and adults.
A cold may cause:
-
Runny or blocked nose
-
Sneezing
-
Cough
-
Mild fever
-
Irritability
-
Reduced appetite
-
Difficulty sleeping because of congestion
A cough can also happen because mucus from the nose travels down the back of the throat. In this situation, coughing is one way the body clears the airway.
It is worth remembering that a cough is not always something that should be completely stopped. Coughing helps clear mucus from the airways.
Common Baby Cold Symptoms Parents May Notice
Every baby reacts differently to an illness. Some may remain fairly cheerful, while others become clingy or sleepier than usual.
Common baby cold symptoms include:
Runny Nose
Clear or watery nasal discharge is common at the beginning of a cold. As the illness progresses, mucus may become thicker or change colour. A change in mucus colour by itself does not necessarily mean that a baby needs antibiotics.
Blocked Nose
Nasal congestion can be particularly uncomfortable for babies because they naturally breathe through their nose much of the time, especially while feeding.
A blocked nose may make breastfeeding or bottle feeding more difficult.
Cough
A baby may cough because of mucus irritating the throat or because the respiratory infection is affecting the airways.
A cough can sometimes continue after other cold symptoms have started to improve.
Mild Fever
Some respiratory infections can cause fever. If your baby has a fever, use a thermometer rather than relying only on how warm their forehead feels.
For babies younger than 3 months, a temperature of 38°C (100.4°F) or higher requires prompt medical assessment.
How to Care for a Baby With a Cold and Cough
There is no quick cure for the common cold. In most cases, baby cold care is about keeping your little one comfortable while their body recovers.
1. Keep Your Baby Hydrated
Continue offering breast milk or formula regularly.
A blocked nose can sometimes make feeding harder, so your baby may prefer smaller, more frequent feeds.
Keeping up with feeds is particularly important when a baby is unwell because dehydration can become a concern.
For babies under 6 months, do not replace breast milk or formula with plain water unless your healthcare professional specifically advises it.
2. Help Clear a Stuffy Nose
Nasal congestion can make it difficult for babies to feed and sleep comfortably.
Saline nasal drops or spray designed for babies can help loosen mucus. Gentle suction may then be used when appropriate, particularly before feeding.
Avoid inserting cotton buds or other objects into your baby's nose.
3. Keep the Air Comfortable
If the air inside your home is dry, a clean cool-mist humidifier may make breathing more comfortable for some children. The humidifier needs to be cleaned regularly according to the manufacturer's instructions.
Dry air can make nasal mucus thicker and may make coughing more irritating.
4. Allow Plenty of Rest
Your baby may sleep more while recovering from an infection.
Keep the environment calm and allow your baby to rest according to their usual sleep needs.
Remember that babies should continue to follow safe-sleep recommendations. Do not use pillows, inclined sleep products or other positioning devices to try to improve congestion.
5. Keep Feeding Times Calm
A blocked nose can make feeding tiring.
If your baby struggles to feed because of congestion, clearing the nose gently before feeding may help.
Watch your baby's feeding pattern and wet diapers. A noticeable reduction in feeding or urination can be a reason to contact your pediatrician.
What Can Help With Baby Cough?
Parents naturally want to make their baby's cough disappear as quickly as possible. However, coughing can serve a useful purpose by helping clear mucus from the airways.
For young babies, simple supportive measures are generally preferred over cough medicines. The American Academy of Pediatrics advises against giving young children over-the-counter cough and cold medicines because of safety concerns and limited benefit.
Instead:
-
Continue breast milk or formula feeds.
-
Keep your baby comfortably hydrated.
-
Use saline for a blocked nose when appropriate.
-
Keep the air comfortable.
-
Avoid exposure to cigarette or tobacco smoke.
-
Monitor breathing and feeding.
What About Honey for a Baby's Cough?
Honey should not be given to babies under 1 year of age because of the risk of infant botulism.
So although honey is sometimes discussed as a home remedy for cough in older children, it is not appropriate for infants under 12 months.
Can Babies Take Cough and Cold Medicine?
This is an important question for parents searching for baby cough home care.
Do not give an infant an over-the-counter cough or cold medicine unless a qualified healthcare professional specifically recommends it.
Many products contain multiple ingredients, and medicines intended for older children may not be suitable for babies. The American Academy of Pediatrics advises against OTC cough and cold medicines for young children because they can cause serious side effects and generally do not provide meaningful benefit.
Do not give adult cold medicines to a baby.
If you are considering any medicine for your child, ask your pediatrician or pharmacist about the appropriate product and dose.
When Is a Baby's Cough More Concerning?
A cough associated with a mild cold is often manageable at home when the baby is feeding, breathing and behaving normally.
However, parents should pay close attention to breathing.
Contact a healthcare professional if your baby:
-
Is breathing faster than usual
-
Has difficulty breathing
-
Has wheezing
-
Has persistent coughing spells
-
Is feeding poorly
-
Has significantly fewer wet diapers
-
Becomes unusually sleepy or difficult to wake
-
Is getting worse instead of better
-
Has a cough that continues for several weeks
The NHS advises urgent assessment when a child is struggling to breathe.
The American Academy of Pediatrics also recommends medical attention when babies have breathing difficulties, worsening symptoms or other concerning signs.
Newborn Cold and Cough: When to Seek Medical Help
A cold in a newborn deserves extra attention.
Babies under 3 months are more vulnerable to serious infections. The American Academy of Pediatrics recommends keeping young infants away from people who have colds because an illness that is mild in an older child or adult can be more serious in a young infant.
If your baby is under 3 months and develops a temperature of 38°C (100.4°F) or higher, seek prompt medical assessment.
Do not simply assume that a fever is part of a normal cold.
Baby Cold and Cough: Signs You Should Not Ignore
Sometimes what appears to be a simple cold can develop into a more significant respiratory illness.
Seek urgent medical care if your baby:
-
Is struggling to breathe
-
Has pauses in breathing
-
Has blue or grey lips or face
-
Is extremely difficult to wake
-
Cannot feed because of breathing difficulty
-
Has signs of significant dehydration
-
Has a seizure
-
Appears seriously unwell
Breathing difficulty is particularly important. Signs such as very fast breathing or the skin pulling in around the ribs while breathing should not be ignored.
When a baby looks seriously unwell, do not wait for the cough or cold to improve on its own.
How Long Does a Baby Cold and Cough Usually Last?
A cold does not necessarily disappear in a couple of days.
Nasal symptoms may last for around one to two weeks, while a cough can sometimes continue for two to three weeks.
What matters is the overall direction.
If your baby gradually becomes more comfortable, starts feeding normally and their symptoms begin to settle, that is generally reassuring.
If symptoms are becoming worse, new symptoms appear or your baby is not recovering as expected, contact your pediatrician.
How Can Parents Reduce the Spread of Colds?
Babies can catch respiratory viruses from close contact with people who are sick.
Simple hygiene habits can reduce the spread:
-
Wash hands before touching or feeding the baby.
-
Ask visitors who are unwell to postpone their visit.
-
Avoid sharing cups, utensils or towels.
-
Clean frequently touched surfaces.
-
Encourage older siblings to wash their hands.
-
Keep young babies away from people with active cold symptoms when possible.
The American Academy of Pediatrics particularly recommends protecting babies under 3 months from people who have colds.
Final Thoughts on Baby Cold and Cough
A baby cold and cough can make everyday routines more difficult, but many uncomplicated colds improve with time and supportive care.
Instead of looking for a quick fix, focus on the basics: keep your baby appropriately hydrated, help ease nasal congestion, provide a comfortable environment and give them plenty of opportunities to rest.
Most importantly, watch your baby's overall condition. Feeding, wet diapers, alertness and breathing can provide useful clues about how your baby is coping with an illness.
If your baby has difficulty breathing, is not feeding properly, becomes unusually sleepy or develops other concerning symptoms, contact a healthcare professional. And remember that a fever of 38°C (100.4°F) or higher in a baby under 3 months requires prompt medical attention.
