Snoring in Babies and Toddlers
The short answer
Occasional snoring during a cold or when congested is common and usually harmless. However, habitual snoring - snoring most nights when healthy - occurs in about 10-12% of children and may indicate a condition called obstructive sleep apnea (OSA), which can affect development, behavior, and health if untreated. Any child who snores regularly when not sick should be evaluated by their pediatrician.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
Newborns are noisy breathers - they snort, gurgle, and make all sorts of sounds during sleep, which is usually related to their small nasal passages and normal nasal congestion. Occasional snoring during a cold is expected. However, true habitual snoring, snoring with pauses in breathing, or snoring with rib retractions (skin pulling in between the ribs) at this age should be evaluated, as it may indicate a structural issue such as laryngomalacia or other airway abnormality.
Some congestion-related snoring is common, especially if your baby has a cold or allergies. Babies who breathe through their mouth during sleep or snore most nights even when well should be discussed with the pediatrician. The most common causes of habitual snoring at this age include nasal congestion from milk or formula reflux and, less commonly, enlarged adenoids.
By this age, habitual snoring is more likely to be related to enlarged adenoids or tonsils, which are growing as part of normal immune development. Signs that snoring may be affecting your baby include restless sleep, unusual sleeping positions (neck extended, sleeping sitting up), sweating during sleep, and daytime mouth breathing. If snoring is loud and occurs most nights, mention it at your next well-visit.
Adenoids and tonsils are at their largest relative to the airway during the toddler and preschool years, making this a peak age for snoring and obstructive sleep apnea. Warning signs include snoring most nights, observed pauses in breathing, gasping or choking during sleep, restless sleep, night sweats, and bedwetting in previously dry children. Daytime consequences may include behavioral issues, hyperactivity, difficulty concentrating, and excessive daytime sleepiness. An evaluation and possible sleep study may be recommended.
What Should You Do?
When to take action
- Your baby snores occasionally during a cold or when congested, and the snoring resolves when the illness clears
- A newborn makes various noisy breathing sounds during sleep but breathes comfortably and feeds well
- Very mild, quiet snoring occurs occasionally but your child sleeps well, breathes regularly, and has no daytime symptoms
- Your baby or toddler snores most nights even when not congested or sick
- Your child is a habitual mouth breather during the day and night
- Snoring is accompanied by restless sleep, unusual sleeping positions, or night sweats
- Your toddler has behavioral issues such as hyperactivity, inattention, or excessive crankiness that could be related to poor sleep quality
- You observe pauses in your baby's breathing during sleep, followed by gasping or choking - this may be obstructive sleep apnea and needs prompt evaluation
- Your baby has noisy breathing with visible rib retractions, nasal flaring, or color changes (blue lips or face) during sleep - seek immediate medical attention

Related Sleep Concerns
How Long Should Baby Be Awake Between Naps?
The ideal awake time between naps (called a "wake window") increases as your baby grows. Newborns may only handle 45-90 minutes awake, while toddlers can manage 4-6 hours. Getting wake windows right is one of the most effective ways to improve nap quality, because both too-short and too-long wake times lead to poor sleep.
Is a Bath Before Bed Really Necessary?
A nightly bath is not medically necessary and some babies with sensitive skin do better with less frequent bathing. However, a warm bath can be a powerful sleep cue because the subsequent body temperature drop triggers melatonin production. If you include a bath, keep it calm and warm rather than stimulating.
How Long Should the Bedtime Routine Be?
An ideal bedtime routine for babies and toddlers is 20-30 minutes. Shorter routines may not give enough time to wind down, while routines longer than 45 minutes can become a stalling tactic. Consistency in the routine order matters more than exact length.
Is My Baby's Bedtime Too Early?
For most babies over 3 months, bedtime between 6:00-8:00 PM is appropriate. A bedtime that is too early can cause early morning wakings (before 6 AM) or long periods of wakefulness in the middle of the night. However, during nap transitions or on days when naps were short, an earlier-than-usual bedtime helps prevent overtiredness.
Is My Baby's Bedtime Too Late?
For babies over 3-4 months, consistently going to bed after 8:30-9:00 PM may result in overtiredness, which paradoxically makes it harder to fall asleep and stay asleep. Cortisol rises when babies are overtired, leading to more night wakings and early mornings. Moving bedtime earlier, even by 15-30 minutes, often improves overnight sleep quality.
Baby Only Napping 30 Minutes
Short naps of 30-45 minutes are extremely common in babies under 6 months. Your baby is waking at the end of a single sleep cycle and has not yet learned to link cycles together during the day. This is developmentally normal and typically improves on its own between 5-7 months as the brain matures.
