Baby Snoring & Mouth Breathing: What to Know | Parenting Hub
Light snoring with a cold is common. Loud, persistent snoring or constant mouth breathing in a baby needs a check.
Soft snoring during a cold is fine. Persistent loud snoring or mouth breathing when well needs a GP review.
Common causes
Snoring usually reflects a partly blocked airway.
- Cold or blocked nose — short-term
- Enlarged tonsils or adenoids — persistent
- Allergies (less common under 12 months)
- Anatomy — small chin or soft floppy airway
When to see your GP
Persistent loud snoring, gasping, pauses in breathing, or mouth breathing when well, deserve a review. Untreated obstructive sleep apnoea can affect growth, mood and development.
When to seek help
- Pauses in breathing during sleep
- Gasping, choking or restless sleep
- Daytime tiredness, poor feeding, poor growth
- Persistent mouth breathing when well
Common questions
Is snoring with a cold OK?
Yes — it usually settles as the cold clears. Saline drops before sleep can help.
