Managing Cold & Nasal Congestion in Babies Under 1 Year

A blocked or runny nose is one of the most common reasons parents worry about a baby in the first year. Small babies breathe mainly through their nose, so even a little congestion can make feeding and sleep harder. The good news is that most colds are caused by ordinary viruses, settle on their own with simple home care, and do not need medicine. This guide covers how to relieve a blocked nose safely, how to use saline nasal drops, when a cough needs a doctor, and the warning signs that mean you should get help.

This is general information and not a substitute for advice from your pediatrician.

Quick Answer

Most colds in babies are viral and get better in about a week to ten days with rest, plenty of feeds, and gentle nose care. The safest ways to help a blocked nose are saline (salt-water) nasal drops and keeping your baby well fed and upright for feeds. Cough and cold medicines are not recommended for children under 5, and must not be given at all under 2 — your baby’s cold does not need a cough syrup. See a doctor early if your baby is very young, is feeding poorly, is breathing fast or with difficulty, has a high or persistent fever, or simply does not look well to you.

Why Babies Get So Blocked Up

Young babies have small nasal passages, and they have not yet built up immunity to the many common cold viruses around them. A small amount of mucus that an adult would barely notice can block a baby’s nose enough to make feeding and sleeping uncomfortable. Because babies under a few months old prefer to breathe through the nose, congestion can seem worse than it really is.

Colds spread easily through coughs, sneezes and hands, so babies in contact with older siblings or in daycare tend to catch them more often. Several colds a year is common and, on its own, is not a sign that anything is wrong with your baby’s immune system.

Safe Home Care for a Blocked Nose

Most of what helps a baby’s cold can be done at home:

• Saline nasal drops — plain salt-water drops loosen thick mucus so it can drain or be cleared. This is the mainstay of safe home care (see the next section for how to use them).
• Keep feeds going — offer breast milk or formula a little more often, in smaller amounts if a blocked nose makes long feeds tiring. Breast milk also helps protect against infection. For babies already on solids, keep offering usual fluids and food as they will take them.
• Feed and rest slightly upright — holding your baby a little more upright during and after feeds can make breathing and swallowing easier.
• Moisten the air — sitting with your baby in a steamy bathroom for a few minutes, or using a cool-mist humidifier that is cleaned regularly, can help loosen mucus. Never leave a baby near hot water or steam unsupervised.
• Wipe, don’t dig — gently wipe away mucus from the outside of the nose; do not push cotton buds or anything inside the nostrils.
• Comfort and sleep — colds are tiring. Extra cuddles, calm surroundings, and letting your baby rest all help recovery.

A word on cough and cold medicines — including decongestants, antihistamines and “cold drops” (the chlorpheniramine + phenylephrine combination is banned for children under 4 in India): these are not recommended for children under 5 years, and must not be given at all to children under 2 — this is the Union Health Ministry’s advisory (2025), issued after deaths linked to contaminated cough syrups. They do not shorten a cold and can cause serious harm. No cough syrup is needed for a baby’s cold. Never buy a cough syrup over the counter, or on a chemist’s or a neighbour’s advice.

What Not to Do

Some common remedies do more harm than good in small babies:

• No camphor or menthol chest or nose rubs (Vicks-type balms) in babies under 2 years — they can worsen airway irritation.
• Never apply anything inside the nostrils — not mustard oil, ghee, breast milk, or ajwain preparations.
• No ajwain potli, smoke, or dhuan near a baby’s face.
• No steam inhalation over a hot vessel — the risk of a scald is real. A few minutes in a steamy bathroom, as described above, is the only safe way to use steam.
• No honey for any baby under 12 months — it carries a risk of infant botulism.
• No antibiotics for a cold — colds are caused by viruses; antibiotics do not help a cold and are not needed unless your doctor diagnoses a bacterial infection.

How to Use Saline Nasal Drops Safely

Saline (sterile salt-water) drops are gentle and can be used as often as needed to soften mucus, including before feeds and before sleep:

• Use a saline preparation made for babies, or one your pharmacist or doctor recommends. Follow the instructions on the pack.
• Lay your baby back gently, or tilt the head back a little.
• Put the recommended number of drops into each nostril and wait a short while to let the mucus loosen.
• For very young babies who cannot blow their nose, a soft nasal aspirator (bulb or syringe type) can gently clear loosened mucus. Use it gently and not too often, as over-suctioning can irritate the delicate lining inside the nose.
• Clean the aspirator after each use as directed.

If you are ever unsure how to use saline drops or an aspirator, ask your pediatrician or pharmacist to show you.

Coughs: What Is Normal and When a Cough Needs a Doctor

A cough is the body’s way of clearing mucus, and a mild cough with a cold often lasts a little longer than the runny nose itself. A cough on its own, in a baby who is feeding, breathing comfortably and otherwise well, can usually be watched at home.

Contact a doctor about a cough if your baby:

• Is breathing fast, noisily, or with visible effort — for example the skin pulling in around the ribs or at the base of the neck, grunting, or the nostrils flaring.
• Has any wheezing or a whistling sound, or seems short of breath.
• Has a cough that is getting worse, is very persistent, or lasts more than 2 weeks — a cough beyond 2 weeks should be reviewed by a doctor, and in India this also prompts checking for tuberculosis, especially if there is weight loss, prolonged fever, or a TB contact at home.
• Has a cough with poor feeding, a high or ongoing fever, or unusual sleepiness or floppiness.
• Has bouts of coughing that end in a whoop, going blue, or vomiting — this needs urgent medical review.

Because it can be hard to judge a baby’s breathing at home, when in doubt it is always safer to have your baby checked.

Home Care vs. When to See a Doctor

Simple home care is usually enough for an older baby with a mild cold who is feeding well, is active between symptoms, and is breathing comfortably.

Seek medical advice promptly if your baby has any of the following. This list is a guide, not a substitute for a doctor’s assessment — if you are worried, get help.

• Your baby is under 3 months old and has a cold, or any fever of 100.4°F (38°C) or higher — a fever at this age needs to be seen the same day, even at night.
• Feeding much less than usual, or clear signs of dehydration such as far fewer wet nappies, a dry mouth, or no tears when crying.
• Difficulty breathing — fast breathing (60 or more breaths a minute in a baby under 2 months, 50 or more from 2–12 months — count for a full minute when your baby is calm), working hard to breathe, ribs or neck pulling in, grunting, flaring nostrils, or any pauses in breathing.
• Fever that is high, that persists, or that keeps coming back, especially with your baby appearing unwell.
• Unusually drowsy, floppy, very irritable, or hard to wake.
• Symptoms that are not improving after about 7–10 days, or that get worse after starting to improve.
• Any bluish colour of the lips, face or tongue — this is an emergency; call 112 or 108 or go to the nearest emergency department immediately.
• Simply that your baby does not look right to you. Parents know their baby best, and that instinct is worth acting on.

The Bottom Line

Colds and a blocked nose are a normal, if tiring, part of a baby’s first year, and most settle with gentle home care — saline drops, plenty of feeds, rest and comfort. Cough and cold medicines have no place in a baby’s cold, and honey should not be given under 1 year. Keep a close eye on your baby’s feeding and breathing, and reach out to your pediatrician early whenever your baby is very young, is not feeding well, is struggling to breathe, or just does not seem themselves.
