My Child Snores Every Night – Could It Be Sleep Apnoea? A Parent’s Guide
Hearing your child snore occasionally when they have a cold is common.
But what if the snoring happens almost every night?
Parents may notice their child breathing loudly through their mouth, tossing around the bed, sweating heavily or sleeping in unusual positions. Some children appear to briefly stop breathing before snorting, gasping or taking a deeper breath.
Understandably, seeing this can be worrying.
One of the questions parents frequently ask in paediatric ENT clinics is:
“How do I know whether my child is simply snoring or actually has sleep apnoea?”
Most children who snore do not have obstructive sleep apnoea. NHS Healthier Together estimates that snoring occurs in around 10% of children, whereas obstructive sleep apnoea affects a much smaller proportion.
However, regular snoring accompanied by disturbed breathing or poor-quality sleep deserves assessment.
This guide explains what parents should look for, why tonsils and adenoids matter, what happens during an ENT assessment and when medical help should be sought.
Why do children snore?
Snoring happens when air passing through the upper airway makes the surrounding tissues vibrate during sleep.
A child's airway is naturally smaller than an adult's. Anything that narrows it further can make noisy breathing more likely.
Common contributors include:
- enlarged tonsils
- enlarged adenoids
- a blocked nose
- colds
- allergic rhinitis
- increased body weight
- differences in facial or airway anatomy
- certain neuromuscular or genetic conditions.
Occasional snoring during a heavy cold is therefore different from a child who snores loudly almost every night.
What are tonsils and adenoids?
The tonsils are two areas of lymphoid tissue visible towards the back of the throat.
The adenoids are similar tissue positioned higher up behind the nose. Parents cannot normally see them simply by looking into their child's mouth.
Tonsils and adenoids are often relatively prominent during childhood.
If they become sufficiently enlarged, they can reduce the space available for air to pass through the nose and throat.
NHS guidance recognises large tonsils or adenoids as factors associated with sleep apnoea.
A child with enlarged adenoids may also:
- breathe through their mouth
- sound blocked or nasal
- sleep with their mouth open
- have persistent nasal obstruction
- experience recurrent glue ear or hearing problems.
Large tonsils may be particularly noticeable when parents look inside the mouth, although tonsil size alone does not tell us whether a child has sleep apnoea.
Symptoms and clinical assessment matter too.
What is obstructive sleep apnoea in children?
Obstructive sleep apnoea—or OSA—means the child's upper airway repeatedly becomes partly or completely obstructed during sleep.
The child continues trying to breathe, but airflow becomes reduced or temporarily stops.
The brain then responds sufficiently to reopen the airway. The child may briefly stir without fully waking.
This sequence can repeat many times during the night.
The NHS describes sleep apnoea as breathing that stops and starts during sleep and lists loud snoring, gasping, snorting, or choking noises, and frequent waking among its characteristic symptoms.
What should parents watch for at night?
Persistent loud snoring is only one part of the picture.
More concerning features include:
- snoring most nights
- pauses in breathing
- gasping or choking sounds
- repeated snorting followed by a deep breath
- very restless sleep
- frequent waking
- sleeping with the neck extended
- unusual sleeping positions
- persistent mouth breathing
- heavy sweating during sleep
- bedwetting beyond the expected age in some children.
Parents often describe the child as looking as though they are “working hard to breathe” during sleep.
A useful practical step is to watch your child when they have been asleep for a while—not simply during the first few minutes after falling asleep.
Should I video my child sleeping?
A short smartphone recording can sometimes be extremely useful.
If safe to do so, record a representative episode showing the child's:
- face
- chest
- breathing sounds
- snoring
- any pauses or gasps.
Do not deliberately wake or disturb the child to create a recording.
A video cannot diagnose sleep apnoea, but it can help an ENT clinician understand what parents are seeing at home—particularly because children are usually awake during clinic appointments.
Can poor sleep affect behaviour during the day?
Yes.
Adults with poor sleep often become sleepy.
Children can present differently.
Some may be tired, but others become:
- irritable
- unusually active
- impulsive
- difficult to settle
- emotional
- poorly concentrated.
Teachers may notice difficulty paying attention or maintaining concentration.
NHS information recognises tiredness, concentration difficulties and mood changes as possible daytime consequences of sleep apnoea.
Sleep should therefore be considered when a child has behavioural or concentration problems alongside significant snoring.
Can sleep apnoea affect school?
Potentially.
Repeated sleep disruption can interfere with restorative sleep.
A child may technically spend ten hours in bed but still have fragmented, poor-quality sleep.
Possible effects include:
- morning difficulty waking
- tiredness
- irritability
- reduced concentration
- poorer attention
- falling asleep during journeys
- difficulties with learning or behaviour.
These symptoms are not specific to OSA. Many other conditions can cause them.
However, when they occur alongside habitual snoring and disturbed breathing, they become more significant.
Is mouth breathing important?
Persistent mouth breathing can be another clue.
Children naturally breathe through their mouths temporarily when their noses are blocked by a cold.
But a child who always sleeps with their mouth open may have persistent nasal obstruction.
Possible causes include enlarged adenoids, allergic rhinitis or other nasal problems.
If a child has nasal blockage as well as snoring, both the nose and throat should therefore be considered rather than focusing solely on the tonsils.
Can allergies make snoring worse?
Yes.
Allergic rhinitis can cause swelling inside the nose, increasing nasal resistance.
A child may then breathe through the mouth and snore more noticeably.
Managing significant nasal allergy can therefore form part of the overall treatment plan in selected children.
However, treating an allergy will not necessarily resolve sleep apnoea if enlarged tonsils or adenoids are causing substantial airway obstruction.
Does every child who snores need a sleep study?
No.
Assessment starts with a detailed history and examination.
Questions may include:
- How many nights each week does the child snore?
- How loud is it?
- Are there witnessed pauses?
- Does the child gasp?
- Is sleep restless?
- Is there mouth breathing?
- Does the child sweat heavily?
- Are there daytime behavioural or concentration issues?
- Is there bedwetting?
- Are there recurrent tonsil infections?
- Is nasal breathing normal?
- Are there other medical conditions?
The tonsils, nose, ears and upper airway are then assessed.
Some children can be managed based on a clear clinical picture. Others may benefit from overnight oxygen monitoring, respiratory polygraphy or a more detailed sleep study.
The appropriate investigation depends on the child's symptoms, age, medical history and clinical findings.
Does my child need their tonsils and adenoids removed?
Not necessarily.
Snoring alone does not automatically mean surgery is required.
Treatment depends on the cause and severity.
Options may include:
- observation
- treatment of nasal allergy
- addressing weight where clinically appropriate
- further sleep assessment
- tonsil surgery
- adenoid surgery
- combined adenotonsil surgery.
Where enlarged tonsils and/or adenoids are contributing significantly to upper-airway obstruction, surgery may be considered after appropriate assessment.
NICE recognises pharyngeal obstruction and obstructive sleep apnoea among established indications for tonsil surgery, although some NICE sleep-apnoea guidance specifically applies to adults and should not be directly extrapolated as a paediatric treatment algorithm.
Treatment should therefore be individualised rather than based simply on tonsil size.
What about tonsil reduction rather than complete removal?
Different tonsil operations exist.
Depending on the child's clinical circumstances and the surgeon's assessment, discussion may include complete tonsillectomy or an intracapsular/tonsil-reduction technique.
Each approach has potential benefits, limitations and risks.
Families should receive an individual discussion covering:
- why surgery is being considered
- alternatives
- expected recovery
- pain management
- bleeding risk
- possibility of residual or recurrent symptoms
- whether adenoid surgery is also appropriate.
No tonsil procedure should be described as painless or risk-free.
What are the red flags?
Parents should seek prompt medical assessment if their child has significant breathing difficulty while awake, persistent noisy breathing at rest or appears seriously unwell.
Call 999 if a child:
- is struggling significantly to breathe
- develops blue or grey lips or skin
- becomes unusually difficult to wake
- has prolonged breathing pauses with concerning colour change
- collapses
- has severe choking or airway obstruction.
For recurrent night-time pauses, gasping or choking without immediate distress, arrange medical assessment rather than simply waiting for the child to “grow out of it”.
When should my child see a paediatric ENT specialist?
ENT assessment is particularly useful when a child:
- snores most nights loudly
- has witnessed breathing pauses
- gasps or chokes during sleep
- persistently mouth breathes
- has very large tonsils
- has persistent nasal obstruction
- sleeps extremely restlessly
- has recurrent tonsillitis as well as snoring
- has daytime tiredness or concentration concerns
- has a history of glue ear or hearing problems.
The aim is not to operate on every child who snores.
The aim is to distinguish simple snoring from clinically important upper-airway obstruction and identify the most appropriate next step.
Paediatric snoring and sleep assessment in London and Essex
Persistent snoring can affect the whole family. Parents may spend nights listening for the next breath while children themselves may experience disrupted sleep without realising it.
Mr Gaurav Kumar, Consultant ENT Surgeon, assesses children with persistent snoring, enlarged tonsils and adenoids, mouth breathing, recurrent tonsillitis and associated paediatric ENT concerns from London, East London, Romford, Ilford, Redbridge, Brentwood, Chelmsford and surrounding areas of Essex.
Where appropriate, assessment can be coordinated with paediatric sleep, respiratory, audiology or other specialist services.
The key message for parents
Not every child who snores has sleep apnoea.
Occasional snoring with a cold is very different from loud snoring almost every night accompanied by pauses, gasping, choking, restless sleep or persistent mouth breathing.
If you regularly watch your child stop breathing and then gasp or snort during sleep, arrange a medical assessment.
A short home video can be helpful, but it cannot replace clinical evaluation.
Most importantly, significant breathing difficulty, prolonged pauses associated with colour change or a child who becomes difficult to wake requires emergency medical help.
FAQs
Is snoring normal in children?
Occasional snoring is common. NHS Healthier Together estimates that around 10% of children snore, and most do not have OSA.
How can I tell snoring from sleep apnoea?
Repeated pauses, gasping, choking, disturbed sleep and significant daytime consequences make OSA more concerning than uncomplicated snoring.
Can large tonsils cause sleep apnoea?
Large tonsils can narrow the upper airway and are an important potential contributor, although tonsil size alone does not diagnose OSA.
Can enlarged adenoids cause snoring?
Yes. Adenoids sit behind the nose and can contribute to nasal obstruction, mouth breathing and sleep-disordered breathing.
Should I record my child snoring?
A short representative video can be useful for showing a clinician, particularly if it captures snoring, breathing effort, or pauses.
Does every child need a sleep study?
No. Whether one is required depends on the clinical history, examination and any additional risk factors.
Does every child with sleep apnoea need tonsil surgery?
No. Management depends on the cause, severity, tonsil/adenoid findings, nasal symptoms and the child's wider health.
When is snoring an emergency?
Significant breathing difficulty, blue/grey colour, severe choking, collapse or difficulty waking a child requires emergency help.
