It's normal for children to snore. Sometimes it's just during a cold or nasal congestion. However, if your child snores frequently, loudly, has difficulty breathing, gasps for breath, or is unusually sleepy, hyperactive, or irritable during the day, you should take them to a doctor for evaluation.

Snoring doesn't necessarily mean every child has obstructive sleep apnea (OSA). However, frequent snoring or other accompanying symptoms should be taken seriously. The following information will help parents monitor their child's symptoms at home more easily, understand the different tests available, and know which treatment is best suited for each child.¹

What is the difference between normal snoring and OSA (Obstructive Snoring)?

Snoring is caused by narrowing of the upper airway during sleep. The tissues in the throat or soft palate vibrate and produce sound. Some children snore occasionally without significant obstruction, but others may have difficulty breathing during sleep, ranging from mild to obstructive sleep apnea (OSA).

OSA (Obstructive Sleep Apnea) is a condition where the upper airway repeatedly narrows or closes during sleep, resulting in incomplete breathing and poor sleep quality. Snoring can provide clues for continued monitoring, but it cannot confirm OSA or determine its severity on your own. History, symptoms, questionnaires, video footage, or tonsil size alone are not sufficient to replace a medical evaluation.³

When observing your child, don't just focus on whether they snore. Also, consider how often they snore, whether they breathe heavily, whether there are periods where they seem to pause and gasp for breath, and whether their behavior or alertness changes during the day.

If a child has OSA (Obstructive Sleep Apnea) and does not receive care, they may experience insufficient sleep, which can affect their behavior, learning, growth, or heart health.⁶ However, snoring alone doesn't mean everyone has these symptoms. Therefore, doctors need to help differentiate general snoring from OSA and look for other possible causes.

What causes a child to snore?

Children can snore for many reasons, and some people have several factors at once. Common causes include:

Enlarged tonsils or adenoids

The tonsils are located on either side of the throat, while the adenoids are behind the nose. When these tissues enlarge, the airway can narrow, especially during sleep. However, the size of the tonsils visible on examination alone is not enough to confirm whether a child has OSA or how severe the condition is.³

The image shows the location of the tonsils on the sides of the throat and the adenoids behind the nasal cavity, which may cause narrowing of the airway. However, tonsil size alone does not confirm OSA or indicate its severity. — The image shows a simplified view of the tonsils and adenoids.⁸ The enlargement may narrow the airways, but the size of the gland is not confirmed to cause OSA.³ If OSA (Osteoarthritis) is suspected, it should be evaluated by a doctor and a PSG (Physiologic¹

Nasal congestion or allergies.

Nasal congestion, rhinitis, allergies, or respiratory infections can cause children to breathe through their mouths and snore more. If this only occurs during a cold, the symptoms may improve once the illness is gone. However, if nasal congestion or snoring persists, it's best to consult a doctor to determine the cause, rather than self-medicating or continuing to use over-the-counter drugs.¹

Overweight or obesity.

Being overweight or obese increases the risk of obstructive sleep apnea in some children. Weight management should be age-appropriate and done in collaboration with a healthcare team; one should not wait for weight loss before diagnosing or treating sleep breathing problems.¹

Facial structure, oral cavity, or airway.

Certain parts of the jaw, tongue, palate, or facial structure can narrow the airway. Therefore, some children require a multidisciplinary team of doctors to determine the exact location of the obstruction and the appropriate treatment.¹⁷

Certain comorbidities or specific conditions.

If a child has Down syndrome, facial or skull abnormalities, neuromuscular disorders, complex comorbidities, or is under 1 year of age, the doctor must assess each child individually based on age and comorbidities. Recommendations for uncomplicated OSA should not replace a comprehensive medical evaluation.¹³⁷

What symptoms should you watch out for?

OSA symptoms in children may differ from adults. Some may not be noticeably sleepy, but instead become more restless, have decreased concentration, or become easily irritable. Observe your child both during the day and at night and describe your symptoms to your doctor; this will help provide a more complete picture.⁶⁷

Symptoms that can be observed at night.

Frequent or loud snoring.
It was like my breath stopped for a moment, then I suddenly jolted.
You have to breathe hard enough that your chest or neck dimples.
Breathing through your mouth, dry throat, or waking up frequently to drink water.
Restless sleep, excessive sweating, or frequently tilting the head back.
Resuming bedwetting, even though this never happened before, or with other accompanying symptoms.¹⁶⁷

If you see these symptoms, you should take your child to a doctor for evaluation. However, one symptom alone is not enough to diagnose OSA, nor can it indicate its severity.

Symptoms that may be visible during the daytime.

Difficulty waking up, feeling sleepy during the day, or accidentally falling asleep at an inappropriate time.
Becoming more mischievous, easily irritated, experiencing mood swings, or having difficulty controlling their behavior.
Concentration, memory, or academic performance change.
Headache or dry mouth in the morning.
Abnormal growth or weight.⁶⁷

Daytime symptoms can be caused by many factors, so don't conclude a child has OSA based solely on behavior or academic performance. Other causes should be considered as well.

Things to write down before taking your child to the doctor.

Before taking your child to the doctor, try writing down their symptoms, as many things happen while they're sleeping. Here's what you might notice:

How many nights a week does your child snore, and how long has this been going on?
Does he snore loudly all the time, or only when he has a cold or allergies?
Does she have difficulty breathing, gasp, her chest sinks in, or exhibit any unusual sleeping positions?
How do your behavior, concentration, or learning change when you feel sleepy during the day?
Do you have allergies, are you taking any medication, have your weight changed, have any underlying medical conditions, or have you received any previous treatments?

If it's safe and won't disturb your child, you can record a short video showing their breathing patterns and chest movements. This clip can help doctors understand what's happening at home, but it cannot be used to confirm OSA or as a substitute for a sleep study.³

When should you take a child who snores to see a doctor?

You should schedule a doctor's appointment for your child if they snore frequently or loudly, have difficulty breathing, gasp for breath, breathe heavily, breathe through their mouth excessively, toss and turn during the night, or exhibit changes in behavior, concentration, alertness, or growth during the day.¹

If a child has obesity, Down syndrome, craniofacial abnormalities, or neuromuscular disorders, the doctor will consider any co-existing conditions, as these children may require a different approach than typical children.⁴⁷ If you have already received treatment but the snoring persists or the symptoms return, you should return for a reassessment by the treatment team. Do not conclude on your own that the treatment is ineffective or leave it untreated.

Emergencies that shouldn't wait.

If a child stops breathing, has severe difficulty breathing, or their lips or skin turn bluish, gray, or unusually pale, seek emergency medical help immediately.⁹ ¹⁰ ¹¹

What tests will the doctor perform?

Doctors will begin by asking about symptoms at home, then examine the nose, mouth, tonsils, breathing, facial structure, growth, and co-existing conditions. Some individuals may need to see a pediatrician, sleep specialist, ENT specialist, or a multidisciplinary medical team.

Taking a medical history and performing a physical examination is very helpful, but it still cannot accurately differentiate general snoring from OSA (Obstructive Snoring) or determine its severity in all children.¹³ If a doctor suspects OSA (Obstructive Sleep Apnea), they often consider a polysomnography (PSG) sleep study. If PSG is not accessible, the doctor may choose another appropriate test or refer the patient to a specialist.¹³

What is PSG?

A PSG (Sleep Assessment Test) is a full-night sleep study. The team records breathing, airflow, chest movement, oxygen levels, pulse, and sleep stages. This data helps doctors determine if there is any obstruction, how severe it is, and how to manage it.

The AASM states that overnight, staffed monitoring (PSG) is the standard for diagnosing OSA in children and may be used in some cases, such as adjusting PAP pressure or monitoring certain groups of children after treatment.³

Can a Home Sleep Test be used as an alternative to a PSG in children?

The AASM states that it does not recommend the standard adult Home Sleep Apnea Test for diagnosing OSA in children under 18 years of age because there is insufficient data available for adult use.²

You should not self-medicate or choose tests based on advertisements. If you suspect OSA, have a doctor evaluate your child and choose the appropriate testing method. For the diagnosis of children, the guidelines referenced in this article use overnight PSG (Postpartum Grafting).¹³

What are the treatment options?

There's no one-size-fits-all treatment. The doctor will assess whether it's just snoring or also obstructive sleep apnea (OSA), where the obstruction is, the severity of the symptoms, the child's age, and any co-existing conditions, then choose the most appropriate treatment for each child.¹⁴⁵

If there are co-existing conditions, the doctor may prescribe medication based on the cause, but the doctor must determine the type of medication, duration, and monitoring. There is no over-the-counter anti-snoring medication, and you should not self-medicate with antibiotics, allergy medication, or other drugs to treat OSA.¹

The following examples illustrate some of the things a doctor might consider; it's not a list of options to choose from.

Manage nasal conditions, comorbidities, and weight.

Avoid secondhand smoke.⁷ Manage nasal congestion or allergies as directed by your doctor. If you are overweight or obese, manage your weight in collaboration with your healthcare team. Weight management is supplementary and should not delay necessary OSA testing or treatment.¹

Tonsillectomy and adenoidectomy

If OSA (obstructive sleep apnea) is detected along with enlarged tonsils or adenoids, the doctor may consider surgery if deemed appropriate. Some children may retain OSA after surgery.⁴⁵

CPAP is for some children.

Some children may be able to use a CPAP machine. An experienced team will help select the right mask, set the pressure, and monitor their progress. You should not buy the machine or adjust the pressure yourself.¹³⁵

If your child still snores after treatment, what should you do?

If, after treatment, your child continues to snore, has difficulty breathing, or exhibits daytime symptoms such as difficulty waking up, excessive sleepiness, increased restlessness or irritability, decreased concentration, or changes in academic performance, do not conclude that the treatment is ineffective or leave it as is. You should discuss these symptoms with the treatment team to determine what further monitoring or testing is needed.¹⁶⁷

The treatment team may review the child's symptoms, previous test results, treatments used, risk factors, and potential obstructions. The doctor will then determine the most appropriate follow-up or additional testing for that child, which may include sleep studies.¹ You should not adjust the medication, device, or pressure yourself.¹

If symptoms occur after surgery, please see the section "What to do if symptoms persist after surgery" below, which provides specific advice for your case.

Frequently asked questions about children snoring.

Is it normal for children to snore?

Children may snore occasionally when they have a cold or nasal congestion, but if the snoring is frequent, loud, accompanied by interrupted breathing, labored breathing, or occurs during the day, they should be taken to a doctor for evaluation. Don't wait for them to grow up and expect it to go away on its own.⁶

Do all children who snore have OSA (Obstructive Sleep Apnea)?

No, snoring is just a signal to observe further. It doesn't confirm OSA (Obstructive Shock Absorption) in the child. Diagnosis requires a history, physical examination, and other tests deemed appropriate by the doctor.¹³

Can video recording a baby sleeping help doctors?

Short video clips showing breathing patterns, chest movements, and suspected breathing difficulties may help doctors understand what's happening at home, but they don't indicate severity and cannot replace polysomnography (PSG) sleep studies.³

Can I get a test at home instead of at PSG?

The AASM states that the standard adult Home Sleep Apnea Test is not recommended for diagnosing OSA in children under 18 years of age.² The doctor will choose the testing method based on the child's age, risk factors, and the availability of the medical facility or the team caring for the child.

Does everyone recover after surgery?

No, tonsillectomy and adenoidectomy are only suitable for children, but OSA (Obstructive Sensitive Arthritis) may persist or recur, so monitoring and follow-up examinations are necessary when deemed appropriate by a doctor.⁴⁵

Can children use CPAP?

Some children can use continuous positive airway pressure (CPAP) machines, such as those who are not suitable for surgery or who still have obstructive sleep apnea (OSA) after surgery. However, an experienced pediatric team must help select the mask, set the pressure, and monitor the results.¹⁵

What should I do if my symptoms persist after surgery?

If your child continues to have OSA (Obstructive Shock Absorption) after tonsil and adenoid surgery, contact the medical team for continued post-operative care. The doctor will assess the symptoms, risk factors, and appropriate test results, as some children may persist with OSA after surgery.⁵ If OSA (obstructive sleep apnea) is still detected, the treatment team may consider re-examination, use CPAP, or further evaluate the location of the obstruction based on its cause. You should not purchase equipment or change treatments on your own.⁵

In summary: What should you do if your child snores?

Not all children who snore have OSA (Obstructive Sleep Apnea). However, if they snore frequently, have interrupted breathing, labored breathing, or exhibit changes in behavior and alertness during the day, they should be evaluated by a doctor. If a doctor suspects OSA, they will usually consider performing a full-night PSG (Sleep Apnea Test). Furthermore, a standard adult home sleep apnea test should not be used as a substitute for a child's test.²³

Treatment may begin with managing factors that worsen symptoms, treating allergies, surgery, or using CPAP, depending on the cause and suitability. Children who still have symptoms after treatment should have follow-up appointments. Do not adjust medication, the device, or the pressure yourself.¹⁴⁵

If you're looking for a medical facility for a sleep study, ask beforehand if they have a team and testing systems for children, as each facility offers different services.
