Helping Your Child Recover from a Cough: Home Care & Warning Signs
A cough is one of the most common reasons parents seek medical advice for babies and young children. It can be upsetting to hear your child coughing, especially at night, but a cough is often the body’s way of clearing mucus, irritation or infection from the airways.
Many coughs are caused by viral infections such as colds, flu, RSV or other respiratory illnesses. These often improve with supportive care. However, some coughs may need medical assessment, especially if your child is struggling to breathe, feeding poorly, wheezing, or not improving as expected.
Dr Lerissa Pillay, Specialist Paediatrician, provides family-centred paediatric care for babies, children and adolescents, including support for coughs, colds, respiratory infections, asthma, allergies and acute childhood illnesses.
Why Do Children Cough?
Coughing is a protective reflex. It helps clear mucus, dust, germs or irritation from the throat and airways.
In children, a cough may be linked to:
A common cold
Flu or another viral infection
RSV or bronchiolitis
Croup
Post-nasal drip
Asthma or allergies
Sinus irritation
Pneumonia or a chest infection
Exposure to smoke, vaping, dust or strong smells
Choking or inhaling something accidentally
Parents do not need to diagnose the exact cause at home. The important thing is to watch how your child is breathing, drinking, feeding, sleeping and behaving.
When Is a Cough Usually Not Serious?
A cough is often less concerning if your child is otherwise well.
This means your child is:
Breathing comfortably
Feeding or drinking well
Passing urine or having wet nappies as usual
Alert and responsive
Playing or interacting between symptoms
Not wheezing
Not showing signs of chest pulling or breathing difficulty
Even when a cough sounds unpleasant, it may still be part of a normal viral illness. Some coughs can linger after a cold as the airways recover.
Safe Home Care Measures for a Child’s Cough
If your child has a mild cough and is otherwise well, home care can help keep them comfortable while they recover.
Encourage fluids
Fluids help prevent dehydration and can soothe an irritated throat. Babies should continue breastmilk or formula feeds. Older children can be offered water and other suitable fluids.
Keep the nose clear
A blocked nose can make coughing worse, especially at night or during feeds. Saline drops or spray may help loosen mucus, particularly in babies and young children.
Use a comfortable sleeping environment
Keep the room comfortable and well-ventilated. Avoid overheating the room or over-bundling your child in too many layers.
Try honey only if your child is over 1 year old
For children over 1 year, honey may help soothe a cough. Honey must not be given to babies under 12 months old.
Avoid smoke and strong irritants
Cigarette smoke, vaping, dust, aerosols and strong fragrances can irritate the airways and worsen coughing. Keep your child’s environment as clean and smoke-free as possible.
Allow rest
Children often need more sleep when they are unwell. Gentle activity is fine if your child feels up to it, but they should not be pushed to continue normal routines if they are tired.
Be Careful with Cough Medicines
Cough mixtures and over-the-counter cold medicines are not always suitable for babies and young children. Some can cause side effects or may not be helpful for the type of cough your child has.
Do not give adult cough medicine to a child. Always check with a doctor or pharmacist before using cough or cold medication, especially for young children, babies, or children with existing medical conditions.
If your child has been prescribed an inhaler, allergy medication or other treatment, use it exactly as directed by your healthcare provider.
Signs That a Cough May Be Serious
Some coughs need medical attention. Parents should seek medical advice if the cough is worsening, lasting longer than expected, or affecting breathing, feeding or sleep.
Book a medical assessment if your child has:
A cough lasting longer than 3 weeks
A cough that keeps returning
Wheezing or noisy breathing
A cough that is worse at night or with exercise
Fever that is not improving
Chest pain
Poor feeding or reduced drinking
Fewer wet nappies or signs of dehydration
Vomiting after coughing
Cough with weight loss, tiredness or poor growth
A known condition such as asthma, heart disease, lung disease or a weakened immune system
A persistent, recurring or worsening cough should be assessed to check for conditions such as asthma, allergies, infection or other respiratory concerns.
When to Seek Urgent Medical Help
Seek urgent medical care if your child:
Is struggling to breathe
Has ribs, chest or neck pulling in with each breath
Has blue, grey or very pale lips, tongue or skin
Is grunting, gasping or pausing in breathing
Has a harsh sound when breathing in
Is unusually sleepy, floppy, confused or difficult to wake
Cannot drink or feed because of the cough or breathing difficulty
Shows signs of dehydration
Has coughed or choked after possibly inhaling food, a toy or another object
Has a seizure
Is getting worse quickly
If you are worried about your child’s breathing, do not wait. Rather have them assessed urgently.
Cough in Babies: What Parents Should Watch For
Babies need closer monitoring because they can become tired quickly when they are unwell. A cough may interfere with feeding, sleep and breathing.
Seek medical advice if your baby:
Is feeding less than usual
Has fewer wet nappies
Is breathing faster than normal
Has chest pulling or flaring nostrils
Is unusually sleepy or difficult to wake
Has a fever
Has pauses in breathing
Looks pale, blue or grey
Young babies should be assessed earlier, especially if they are under 3 months old, were born prematurely, or have an existing medical condition.
Could a Cough Be Asthma or Allergies?
Not every cough is caused by infection. A cough that keeps coming back, worsens at night, appears during exercise, or is linked to wheezing may need assessment for asthma or allergies.
Other clues may include eczema, hay fever symptoms, a family history of asthma, or coughing after exposure to dust, pets, pollen, smoke or cold air.
A paediatrician can help assess whether your child’s cough is part of a temporary infection or whether further investigation and treatment may be needed.
When to Book a Paediatric Consultation
You should consider booking a paediatric consultation if your child has a cough that is persistent, recurring, worsening, affecting sleep, linked to wheezing, or not improving as expected.

FAQs About Coughs in Children

What can I give my child for a cough at home?
Supportive care may include fluids, rest, saline drops for a blocked nose, a comfortable sleeping environment and avoiding smoke or irritants. Honey may be used only for children over 1 year old.
Can I give honey to my baby for a cough?
No. Honey should not be given to babies under 12 months old because of the risk of infant botulism.

You should seek medical advice if your child is struggling to breathe, wheezing, feeding poorly, becoming dehydrated, unusually sleepy, coughing for more than 3 weeks, or getting worse.
Is a night-time cough a sign of asthma?
