Blocked Noses in Babies: Questions About Saline and Gentle Care

A snuffly sound can be especially noticeable when your baby feeds or lies down. Before reaching for a product, look at their breathing and how well they are feeding. Nasal care may ease mucus at the nose, but it must not delay help for a baby who is struggling.

Call your local emergency service for pauses in breathing, blue or grey lips or tongue, difficulty waking, or obvious effort to breathe. If breathing is comfortable but feeds are becoming much smaller or nappies less wet, seek medical advice promptly.

What should I look for in saline?

Ask for plain saline suitable for your baby’s age. Check that no decongestant or other medicine has been added, and follow the product’s directions for use and storage. A saline dropper, a forceful rinse and a medicated nasal spray are not interchangeable.

Using a prepared product avoids having to judge a homemade mixture. If the instructions are unclear or the nozzle seems unsuitable for a small baby, ask the pharmacist to show you how to use it. Keep the container clean as directed and do not share it between children.

Saline may loosen mucus enough to make feeding more comfortable. It is not a cure for a cold, and a continuing noise does not mean you need to keep adding more. Our baby cold guide focuses on maintaining feeds and watching the overall illness.

Is suction always needed?

Gentle suction with a device designed for babies can sometimes help when mucus is interfering with a feed. Ask a professional to demonstrate the device and use it as directed. With a bulb syringe, squeeze the bulb before positioning its tip at the nostril, then release gently. Do not push a device deep inside the nose.

Avoid repeated attempts to achieve a completely silent nose. Stop if care causes bleeding, marked distress or seems to make things worse, and seek advice. For a baby with bronchiolitis, suction is not a routine treatment to keep repeating at home; the care team should guide whether it is appropriate for feeding difficulty caused by secretions.

If advised to try nasal care before a feed, prepare everything first and allow time for your baby to settle. Wipe visible mucus gently from the outside. Do not insert cotton buds into the nostrils.

Should I change the sleeping position?

Keep placing your baby on their back on a firm, flat sleep surface, with the space clear of soft items. Do not use pillows, wedges, rolled towels or a raised mattress for congestion. Sleeping in a rocker or swing is not a substitute for a safe sleep space.

Holding your baby upright while both of you are awake is different from letting them sleep propped up. If they fall asleep, transfer them to their usual safe sleep space. For a baby who cannot breathe comfortably lying down, seek medical assessment rather than solving the problem with an incline.

What should I tell the clinician?

Describe how long the congestion has lasted, whether feeds are affected, and any cough or change in breathing. Mention what products you have used. If you took a temperature, give the actual reading and measurement method; do not adjust the number yourself.

A young baby’s fever has particular urgency, as explained in the fever guide. If new chest sounds or coughing develop, the cough guide can help you describe them, but you do not need to identify the cause before asking for help.
