Baby sniffling/snorting?

Baby sniffling/snorting usually stems from two main causes:

Nasal congestion: This is the most common cause. Babies' nasal passages are so narrow that even a little mucus makes breathing difficult, so your baby sniffles trying to get air. Causes include:

• Common cold / upper respiratory infection
• Dry air (especially in winter with indoor heating)
• Teething-related nasal membrane swelling
• Allergic reactions (less common)

Rhythmic sniffling / habit: Some babies make rhythmic sniffling sounds while falling asleep or when bored; this is usually harmless.

When to worry:

• If sniffling comes with chest wall retractions, rapid breathing, or wheezy sounds (signs of breathing difficulty)
• If your baby keeps pulling away from feeding to breathe
• If fever of 38°C or higher is present
• If it lasts longer than 2 weeks—in these cases see your pediatrician.

Home care options:

• If congested, use saline drops (available at any pharmacy) and a nasal aspirator to clear passages
• Increase room humidity (hang a wet towel or use a humidifier)
• Sleep with head slightly elevated (place a towel under the mattress, never use a pillow)

Sniffling alone usually isn't serious, but watch for accompanying symptoms.
