Understanding coughs in babies and childrenWhen your baby or toddler gets a cough, it can be very distressing for you both. Whether it’s a tiny tickle in your little one’s throat, or a horrible, hoarse cough keeping the family up at night, it’s good to know what’s causing it and what to do about it.
A cough in children is their body’s way of reacting to irritation in the airways. The cough itself is not necessarily a bad thing–it is a normal response by the body to something that it doesn’t want there, such as mucus (phlegm) or a foreign object. Coughing is an important reflex because it helps to remove the irritant out of the windpipe so your child can breathe easily.
Common causes for a child’s cough
Children cough for all sorts of reasons. Some of the most common causes include:
Cold and Flu
It’s common for young children to have 8 or more colds a year 1 , especially if they attend playdates or the nursery. Hundreds of different viruses can cause a cold and children slowly build immunity to these viruses as they catch them. Most colds last between 5 to 7 days and your little one is likely to have sniffles, a sore throat, fever, and headaches as they recover. A child’s body produces a lot of mucus as it fights off a cold and coughing is the body’s way of trying to clear that mucus away as it trickles down the back of the throat. This cough is normal and can sometimes last a few weeks after the other symptoms have gone away.
Croup is a common childhood condition that can cause a very distinctive “barking” cough that often sounds like a seal barking 2 . Symptoms are usually worse at night and it’s not uncommon for parents to first discover croup after waking up to a loud, barking sound coming from their child’s room. Other symptoms may include a runny nose, fever, high-pitched sounds when breathing in (stridor), and a sore throat. Mild cases of croup usually go away within 48 hours on their own, but if your child is struggling to breathe, looks unusually pale or discoloured, or is getting worse, see your doctor immediately.
Asthma is a common lung condition that often starts in childhood and is caused by swelling and inflammation of the breathing tubes 3 . Children with asthma often struggle with wheezing, breathlessness, a tight chest and frequent coughs. Certain triggers (such as exercise, pollution or cold air) can trigger an asthma attack, where these symptoms become temporarily worse and may be life-threatening if not treated 4 . Coughing is rarely the only symptom in a child with asthma; difficulty breathing, chest tightness, and wheezing are often the main symptoms. Asthma is managed with an inhaler that opens up the airways so breathing becomes easier 3 .
Allergies or hay fever can often cause a child to cough too. Hay fever can also cause a chronic runny nose, watery eyes and an itchy throat in babies and toddlers. As the excess mucus in the nose trickles down the back of your child’s throat, they will feel the need to cough to clear it away. Hayfever is often worse during spring and summer when there is a higher level of pollen in the air 5 . Common household allergens such as dust-mites and mould can also worsen allergy symptoms throughout the year. Reduce allergy symptoms by removing any obvious allergens,such as dust or mould, from your child’s environment.
Reflux can cause a burning feeling in the chest as stomach acid travels up towards the throat and may cause a cough in children 6 . This can happen when the acidic contents of the stomach travel back through the throat and trigger the natural cough reflex. Your child may complain of a “tummy ache” since they may be too young to describe the burning sensation in their chest. If you suspect reflux, speak to your doctor about possible treatments.
Whooping coughWhooping cough (pertussis) is a highly contagious bacterial infection of the lung and airways that can make babies and young children very ill 7 . It often starts with symptoms of a common cold which then turn into violent coughing fits. The cough makes a whooping sound as the child struggles to take in breaths between coughs, and babies sometimes go blue in the face. Whooping cough is treated with antibiotics and may last up to three months.
When to call the doctor
Sometimes, a cough can be a sign that something serious is going on. Most baby and toddler
coughs are usually caused by something benign but call your doctor if your child:
● is struggling to breathe
● is making whooping sounds when he/she coughs
● is getting worse very quickly or can’t stop coughing
● has had a cough for longer than 3 weeks.
If your child coughs up blood, seek medical help immediately.
How to treat a cough in babies and children
If your child has a cough, and the cause of that cough is being treated, the next step is to make
them as comfortable as possible. Here are some tips to help soothe them:
● Keep your child well-hydrated to help loosen the mucus. Hot lemon tea with honey may also help to soothe the throat and chest irritation caused by coughing.
● If your child has a cold, try giving them some Nurofen for Children (containing ibuprofen) to ease their aches and pains. Ibuprofen is also an antipyretic, which means it can bring down fevers.
● Use a cool-mist vaporiser in your child’s room at night to stop chest mucus from thickening.
● Do not give cough medicine to babies or toddlers. There are two types of cough medicine that may be used in children over the age of 6: expectorants (which help loosen mucus in wet coughs) and cough-suppressants (which inhibit the cough reflex in the case of a dry cough). Speak to your doctor or pharmacist about which type of cough medicine is suitable for your child’s cough.
