Snoring in Children: Causes, Sleep Apnea Signs & When to See a Pediatrician

🩺 Written & Medically Reviewed by Dr. G
Board-Certified Pediatrician

Occasional snoring during a cold or nasal congestion is common in children. Frequent or habitual snoring, however, should not automatically be considered normal.

Children who snore regularly may have enlarged tonsils or adenoids, nasal congestion, allergies, or another condition that narrows the airway during sleep.

Pay particular attention if snoring occurs along with:

• Pauses in breathing
• Gasping or choking
• Labored breathing
• Mouth breathing
• Very restless sleep
• Unusual sleeping positions
• Frequent nighttime awakenings
• Morning headaches
• Bedwetting
• Daytime sleepiness
• Hyperactivity, irritability, or difficulty concentrating

If your child regularly snores or you notice breathing problems during sleep, discuss it with your pediatrician.

• Occasional snoring with a cold is common.
• Regular snoring in a child deserves attention, particularly when it occurs several nights each week.
• Enlarged tonsils and adenoids are common contributors to obstructive sleep apnea in children.
• Children with sleep apnea may have pauses in breathing, gasping, restless sleep, or labored breathing.
• Poor sleep in children doesn't always cause obvious sleepiness.
• Some children instead become hyperactive, irritable, impulsive, or have difficulty concentrating.
• Don't assume loud snoring is harmless simply because your child appears comfortable during the day.
• A short video or audio recording of your child's sleep can sometimes help your pediatrician understand what you're observing.
• Some children suspected of having sleep apnea may need an overnight sleep study.

You check on your child before going to bed.

They're asleep—but you can hear them from the hallway.

Snore... snore... snore.

Then everything becomes quiet.

You wait.

A few seconds later, your child seems to take a deeper breath and starts snoring again.

Is that normal?

Parents ask pediatricians about snoring frequently, and the answer depends on how often it happens and what else happens while the child sleeps.

A child with a cold may snore temporarily because their nose is congested.

That's very different from a child who snores loudly most nights, struggles to breathe, repeatedly gasps, or seems to stop breathing temporarily.

The important question isn't simply:

“Does my child snore?”

It's:

“How is my child breathing while asleep?”

Why do we snore?

Snoring occurs when air moving through the upper airway causes surrounding tissues to vibrate during sleep.

When the airway becomes narrower, snoring can become more noticeable.

In children, narrowing may occur around the:

• Nose
• Back of the throat
• Tonsils
• Adenoids
• Upper airway

Snoring is a sound.

Sleep apnea is a breathing disorder.

They are not the same thing, although snoring can be an important warning sign of obstructive sleep apnea.

What is obstructive sleep apnea?

Obstructive sleep apnea (OSA) occurs when a child's upper airway repeatedly becomes partially or completely blocked during sleep.

These episodes can disrupt normal breathing and sleep quality.

A child may briefly wake enough to reopen the airway without becoming fully conscious.

This can happen repeatedly during the night.

As a result, a child may spend plenty of hours in bed but still not receive consistently restorative sleep.

Why sleep apnea matters

Healthy sleep is important for:

• Attention
• Learning
• Memory
• Mood
• Behavior
• Growth
• Cardiovascular health
• Overall development

Persistent sleep-disordered breathing therefore deserves appropriate evaluation.

Several conditions can contribute to snoring and obstructive sleep apnea in children.

Enlarged tonsils and adenoids

This is one of the most common causes of obstructive sleep apnea in otherwise healthy children.

Tonsils sit at the back of the throat.

Adenoids are located higher behind the nose.

When these tissues are enlarged, they can narrow the airway during sleep.

Nasal congestion

Children with a cold may temporarily snore because swollen nasal passages make breathing more difficult.

Snoring should improve as the illness resolves.

Allergies

Persistent nasal allergies can contribute to:

• Nasal congestion
• Mouth breathing
• Noisy breathing
• Poor-quality sleep

Excess body weight

Excess tissue around the airway can increase the risk of obstructive sleep apnea in some children.

Weight is only one possible contributor, however. Children of any body size can develop sleep apnea.

Facial or airway anatomy

Differences in the structure of the jaw, face, tongue, nose, or airway may contribute to airway narrowing.

Certain medical or developmental conditions

Some neuromuscular, craniofacial, genetic, and developmental conditions can increase the risk of sleep-disordered breathing.

Your pediatrician can assess your child's individual risk factors.

Symptoms during sleep

Watch for:

• Loud or frequent snoring
• Pauses in breathing
• Gasping
• Choking sounds
• Snorting
• Labored breathing
• Mouth breathing
• Restless sleep
• Frequent position changes
• Sleeping with the neck extended
• Unusual sleeping positions
• Frequent awakenings
• Excessive sweating during sleep
• Bedwetting, particularly when unexpected or persistent

Symptoms during the day

Poor-quality sleep can affect daytime functioning.

A child may experience:

• Difficulty waking in the morning
• Morning headaches
• Daytime sleepiness
• Irritability
• Mood changes
• Difficulty concentrating
• Poor attention
• Impulsivity
• Hyperactive behavior
• Learning difficulties
• Declining school performance

An important point for parents

Adults who don't sleep well often look tired.

Children may behave differently.

Some sleep-deprived children become more active rather than less active.

A child who is restless, impulsive, emotional, or having trouble concentrating may have many possible explanations—but sleep should be part of the conversation.

1. Listen to your child's breathing

Don't focus only on how loud the snoring is.

Listen for the pattern.

Does your child breathe steadily?

Or do you hear:

Snoring → silence → gasp → snoring again?

Repeated breathing pauses deserve medical attention.

2. Check on your child while they're sleeping

Occasionally observe:

• Chest movement
• Breathing effort
• Mouth breathing
• Sleeping position
• Restlessness

You do not need to spend the night watching your child.

You're simply looking for patterns that may help your pediatrician.

3. Record what you're seeing

If it can be done safely without disturbing your child, a brief video or audio recording can be useful.

Try to capture:

• Snoring
• Breathing pattern
• Chest movement
• Gasping
• Unusual sleeping positions

Bring the recording to your pediatric appointment.

A recording doesn't diagnose sleep apnea, but it can provide useful information.

4. Keep a short sleep diary

For one or two weeks, record:

• Bedtime
• Wake time
• Snoring
• Nighttime awakenings
• Breathing concerns
• Bedwetting
• Morning symptoms
• Daytime behavior

Patterns can be more informative than a single difficult night.

5. Maintain healthy sleep habits

Good sleep habits won't correct a physically obstructed airway, but adequate sleep is still important.

Maintain:

• Consistent bedtime
• Age-appropriate sleep duration
• A calming bedtime routine
• Limited screens before bed
• A comfortable sleep environment

6. Discuss persistent nasal symptoms with your pediatrician

If your child regularly has:

• Nasal congestion
• Sneezing
• Itchy nose
• Mouth breathing
• Allergy symptoms

tell your pediatrician.

Treating an underlying nasal problem may improve breathing for some children.

Don't assume habitual snoring is normal

Children can certainly snore occasionally.

But regular loud snoring deserves a closer look.

Don't diagnose sleep apnea based on snoring alone

Not every child who snores has obstructive sleep apnea.

A proper evaluation considers the child's complete history, examination, symptoms, and sometimes sleep testing.

Don't ignore breathing pauses

Repeated pauses followed by gasping, choking, or struggling to breathe should be reported to your pediatrician.

Don't use adult anti-snoring devices

Products marketed for adult snoring may not be appropriate or safe for children.

Don't start medications or supplements solely for snoring without medical guidance

Treatment depends on the underlying cause.

The right treatment for allergies may be very different from the treatment for enlarged tonsils, adenoids, or another airway problem.

Don't assume behavior problems are always behavioral

If your child has new or persistent hyperactivity, irritability, attention difficulties, or school problems, consider whether sleep could be contributing.

Contact your pediatrician if your child:

• Snores frequently or most nights
• Snores loudly
• Regularly breathes through the mouth while sleeping
• Has pauses in breathing
• Gasps or chokes during sleep
• Appears to struggle to breathe
• Sleeps very restlessly
• Sweats excessively during sleep
• Frequently awakens
• Sleeps in unusual positions to breathe
• Has persistent bedwetting along with other sleep symptoms
• Is unusually sleepy during the day
• Has frequent morning headaches
• Has significant irritability or hyperactivity
• Has difficulty concentrating
• Has declining school performance
• Has poor growth or another health concern

You don't need to determine whether your child has sleep apnea before calling.

That's what the evaluation is for.

Seek immediate medical attention if your child:

• Has severe difficulty breathing
• Is struggling significantly to get air
• Has blue, gray, or unusually pale lips or skin associated with breathing difficulty
• Has a prolonged breathing pause and does not quickly resume normal breathing
• Becomes unresponsive
• Is unusually difficult to awaken
• Has another symptom that makes you believe they are in immediate danger

Snoring by itself is generally not an emergency.

Significant breathing difficulty is.

• Your pediatrician will usually begin by taking a detailed sleep history.

  You may be asked:

  • How often does your child snore?
  • How loud is it?
  • Does it happen every night?
  • Have you seen pauses in breathing?
  • Does your child gasp or choke?
  • Does your child breathe through their mouth?
  • Is sleep restless?
  • Does your child sweat excessively?
  • Is your child difficult to wake?
  • Is there daytime sleepiness?
  • How is behavior?
  • How is school performance?
  • Is there bedwetting?
  • Does your child have allergies or chronic congestion?

• Your pediatrician may examine your child's:

  • Nose
  • Mouth
  • Throat
  • Tonsils
  • Jaw and airway
  • Breathing
  • Growth pattern
  • Blood pressure and general health as appropriate

• ---

  Will my child need a sleep study?

  Not every child who snores needs a sleep study.

  However, when obstructive sleep apnea is suspected, your pediatrician or specialist may recommend polysomnography, commonly called an overnight sleep study.

  During the study, several things can be monitored while your child sleeps, such as:

  • Breathing
  • Oxygen levels
  • Heart rate
  • Sleep stages
  • Airflow
  • Chest and abdominal movement

• The results can help determine whether sleep apnea is present and how significant it is.

  What treatment might be recommended?

  Treatment depends on the cause and severity.

  Options may include addressing nasal allergies or congestion, evaluating enlarged tonsils and adenoids, referral to an ear, nose and throat specialist, weight-management support when medically appropriate, or other therapies recommended by a pediatric sleep specialist.

  For some children with obstructive sleep apnea related to enlarged tonsils and adenoids, surgical treatment may be considered.

  There is no single treatment appropriate for every child who snores.

Parents sometimes tell me:

“My child has always snored. I thought that's just how they sleep.”

And sometimes it is simply noisy breathing.

But I don't want parents to ignore habitual snoring, particularly when something else doesn't look right.

Tonight, if your child snores, don't just listen to the volume.

Watch the breathing.

Ask yourself:

Is the breathing steady?

Are there pauses?

Does my child gasp?

Does breathing look like work?

Then think about daytime behavior.

Is my child rested in the morning?

Are they unusually irritable or hyperactive?

Are they struggling to concentrate?

Has school become more difficult?

Sleep isn't simply downtime.

A child's brain and body are doing important work throughout the night.

If you're concerned about how your child is breathing while asleep, bring it up with your pediatrician.

You don't need to know the diagnosis.

You just need to notice the pattern.
