Obstructive Sleep Apnea in Toddlers
Content reviewed against published AAP, NIH guidelines
Last reviewed:
If your baby has been diagnosed with or you suspect obstructive sleep apnea in toddlers, here is what the evidence says.
The short answer
Obstructive sleep apnea (OSA) in toddlers occurs when the airway becomes partially or completely blocked during sleep, causing pauses in breathing, snoring, and disrupted sleep. The most common cause in children ages 2-6 is enlarged tonsils and adenoids. OSA affects 1-5% of children and can lead to behavioral problems, daytime sleepiness, poor growth, and learning difficulties if untreated. Treatment often involves adenotonsillectomy (surgical removal of tonsils and adenoids).

- Usually normal when: Baby occasionally snores when congested from a cold

“Fever itself is not an illness — rather, it is a sign or symptom that the body is fighting an infection. Fever stimulates certain defenses, such as the white blood cells, which attack and destroy invading bacteria.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
0-3 months
True obstructive sleep apnea is uncommon in newborns but can occur in babies with craniofacial abnormalities (like Pierre Robin sequence), severe laryngomalacia, or neurological conditions. Central apnea (brain-related pauses) is more common in premature infants. If your newborn has been observed to stop breathing during sleep, snore loudly, or seem to struggle to breathe while sleeping, report this to your pediatrician immediately.
3-6 months
Snoring in young babies can occur from nasal congestion or laryngomalacia and is usually not OSA. However, if your baby consistently snores loudly, has observed pauses in breathing during sleep, or seems to work hard to breathe while sleeping (retractions, head extension), mention this to your pediatrician. Babies who sleep with their neck extended backward may be compensating for an obstructed airway.
6-12 months
As babies grow, mild snoring from nasal congestion usually improves. Persistent loud snoring, especially with observed pauses or gasping, is not normal at any age. Risk factors for OSA in infants include obesity, Down syndrome, craniofacial abnormalities, and neuromuscular conditions. If your baby has any of these risk factors along with snoring, discuss sleep apnea screening with your pediatrician.
12 months+
OSA becomes more common in toddlers as adenoids and tonsils grow. Signs include loud snoring most nights, observed breathing pauses during sleep, restless sleep, mouth breathing, sweating during sleep, unusual sleep positions (neck hyperextended), and daytime behavioral changes (irritability, hyperactivity). A sleep study (polysomnography) is the gold standard for diagnosis. If tonsils and adenoids are enlarged, adenotonsillectomy is the first-line treatment and resolves OSA in most children.
What Should You Do?
When to take action
- Baby occasionally snores when congested from a cold
- Baby makes soft breathing sounds during sleep without pauses or distress
- Toddler snores lightly for a few nights during an upper respiratory infection
- Baby sleeps quietly in various positions without neck extension or mouth breathing
- Your toddler snores loudly most nights, even when not sick
- You have observed your child pause in breathing or gasp during sleep
- Your toddler is a restless sleeper, mouth breather, or has behavioral or growth concerns
- Your child stops breathing during sleep for more than 10-20 seconds or turns blue -- call 911
- Your child has severe difficulty breathing during sleep with significant retractions or stridor

Bottom line
Most cases of obstructive sleep apnea in toddlers are normal. Talk to your pediatrician if your child stops breathing during sleep for more than 10-20 seconds or turns blue -- call 911.
Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.

My Baby's Head Shape Looks Abnormal
Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.
Achondroplasia (Dwarfism) in Babies
Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
Adenoid Hypertrophy and Breathing
Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.
Adrenoleukodystrophy (ALD) in Babies
X-linked adrenoleukodystrophy (X-ALD) is a genetic disorder affecting about 1 in 17,000 newborns, caused by mutations in the ABCD1 gene on the X chromosome. It primarily affects boys and impairs the breakdown of very long-chain fatty acids (VLCFAs), which accumulate and damage the myelin sheath in the brain and the adrenal glands. The most severe form, cerebral ALD, typically affects boys between ages 4-10 with rapid neurological decline. Newborn screening now enables early detection, and hematopoietic stem cell transplant or gene therapy performed before significant brain involvement can be life-saving.
How to Advocate for Your Child's Needs
You know your child better than anyone, and your observations matter. If you feel something is not right with your child's development or health, you have every right to ask questions, request evaluations, and seek second opinions. Advocating for your child is not being difficult - it is being a good parent.
Agenesis of the Corpus Callosum (ACC)
Agenesis of the corpus callosum (ACC) is a condition in which the corpus callosum — the bundle of nerve fibers connecting the left and right hemispheres of the brain — fails to develop partially or completely. It occurs in approximately 1 in 4,000 births and is one of the most common brain malformations. ACC can be detected on prenatal ultrasound or postnatal MRI. Outcomes vary enormously: some individuals with isolated ACC have normal intelligence and minimal difficulties, while others (especially when ACC occurs alongside other brain abnormalities or genetic syndromes) may have significant developmental delays. The variability means that prenatal counseling and postnatal monitoring are both essential.
