Baby Blocked Nose: How to Clear It Safely | Parenting Hub
Babies breathe mostly through their nose. Learn safe ways to clear a blocked nose with saline drops and when to see a GP.
Babies are nose-breathers, so a blocked nose can make feeding and sleep miserable. Saline drops are the safest, most effective home remedy.
Why baby noses block so easily
Newborn nasal passages are tiny — even a small amount of mucus or dry air can cause noisy 'snuffly' breathing. This is normal and doesn't always need treatment.
Real blockage usually comes with a cold, dry indoor air, or feeding difficulties. Babies don't learn to mouth-breathe well until around 3–4 months, so a fully blocked nose can disrupt feeding and sleep.
Saline drops — the gold standard
Saline (salt water) drops loosen mucus so baby can clear it by sneezing or swallowing. They're safe from birth and you can use them as often as needed.
- Lay baby on their back
- Put 1–2 drops in each nostril
- Wait 30 seconds — baby may sneeze
- Wipe the nose gently with a soft cloth
- Use 10–15 minutes before feeds and sleep
Other safe options
Alongside saline:
- Sit in a steamy bathroom for 10 minutes (never put baby in a hot shower)
- Use a cool-mist humidifier in the bedroom
- Elevate the head of the cot mattress slightly under the mattress (never with pillows)
- Offer small, frequent feeds
What to avoid
- Decongestant medicines — not safe under 6 years
- Vapour rubs on baby's chest — not recommended under 2 years
- Cotton buds inside the nose
- Anything in the cot to prop baby up
When to see a doctor
See your GP if blocked nose lasts more than 10 days, baby is feeding poorly, has fever, or is working hard to breathe.
When to seek urgent care
Fast breathing, sucking in at the ribs or neck, grunting, pauses in breathing, blue lips or baby under 3 months with any fever — same-day medical assessment.
When to seek help
- Fast breathing or working hard to breathe
- Sucking in at the ribs, neck or above the breastbone
- Grunting with each breath
- Pauses in breathing or blue lips
- Baby under 3 months with fever
Common questions
Are nasal aspirators safe?
Yes — gentle silicone or rubber bulb aspirators can help after saline drops. Don't overuse them as they can irritate the lining. Avoid electric suction unless advised by your GP.
Is snuffly breathing without a cold normal?
Yes — many newborns are noisy breathers because their passages are so narrow. As long as baby is feeding well and not working hard to breathe, it's normal.
