When most people picture sleep apnea, they imagine a middle-aged man snoring loudly. That stereotype is so entrenched that sleep apnea in children often goes unrecognized for years — even by pediatricians. But an estimated 1-5% of children have obstructive sleep apnea, and the consequences of missing it are significant.

Pediatric sleep apnea doesn’t look like adult sleep apnea. The symptoms, causes, and treatment are all different.

Why Kids Get Sleep Apnea

In adults, obesity and tissue laxity are the primary drivers. In children, the most common cause is adenotonsillar hypertrophy — enlarged adenoids and tonsils. These tissues sit at the back of the throat and nasal passages, and in some kids, they grow large enough to obstruct the airway during sleep.

Peak adenotonsillar size occurs between ages 3 and 7, which is why pediatric sleep apnea is most commonly diagnosed in this range. Other risk factors include craniofacial abnormalities, Down syndrome, neuromuscular disorders, and childhood obesity.

The Signs That Get Missed

Here’s where things get tricky. The classic adult symptom — excessive daytime sleepiness — is actually uncommon in children with sleep apnea. Instead of getting sleepy, kids often get wired.

Hyperactivity and behavioral problems are among the most commonly missed signs. A child who can’t sit still, has difficulty concentrating, and acts impulsively looks a lot like a child with ADHD. Sometimes the child gets diagnosed with ADHD without anyone investigating whether fragmented sleep might be driving the behavior.

A widely cited study published in Pediatrics found that children who snored frequently at ages 2-6 were 40-100% more likely to develop behavioral problems by age 7.

Mouth breathing during the day is a significant red flag. Children should breathe through their noses. Chronic mouth breathing suggests nasal obstruction, often from the same enlarged adenoids causing nighttime problems.

Unusual sleep positions can be telling. Children with sleep apnea often sleep with their neck hyperextended — head tilted back, chin up — because this opens their airway.

Bedwetting beyond the expected age can be connected. Apnea-related respiratory effort disrupts hormonal signaling that suppresses overnight urine production. Treating the apnea resolves bedwetting in a meaningful percentage of cases.

Poor growth occurs because deep sleep is when growth hormone is most actively secreted. Severe, untreated apnea may reduce growth hormone output and the increased metabolic effort of breathing against an obstruction burns extra calories.

The ADHD Connection

The American Academy of Pediatrics guidelines recommend that children being evaluated for ADHD should also be screened for sleep-disordered breathing. Unfortunately, this isn’t always followed.

If your child has been diagnosed with ADHD and also snores, breathes through their mouth, or has restless sleep, a sleep evaluation is warranted before concluding that medication is the only answer.

Diagnosis and Treatment

The gold standard is overnight polysomnography in a pediatric sleep lab. In children, an AHI of just 1 event per hour is considered abnormal, compared to the adult threshold of 5.

For most children with enlarged adenoids and tonsils, adenotonsillectomy is the first-line treatment. It resolves sleep apnea in approximately 75-80% of cases. For children who aren’t surgical candidates, CPAP therapy is an option, and orthodontic approaches like rapid maxillary expansion are showing promise.

What Parents Can Do

Record your child sleeping. Use your phone to capture audio and video for a few nights. Listen for snoring, breathing pauses, gasping, or choking sounds. Show the recordings to your pediatrician.

If your child snores regularly — more than three nights a week — mention it at their next checkup. Habitual snoring is the single strongest predictor of pediatric sleep apnea. Don’t wait for them to grow out of it. Early treatment prevents years of disrupted sleep and developmental consequences that compound over time.
