A baby may breathe quickly after crying or sound snuffly during a cold. Genuine breathing difficulty, however, needs prompt attention. The most revealing signs of baby breathing problems are how hard your baby works to draw each breath, whether their colour changes, and whether feeding or alertness is affected. These clues help distinguish a noisy nose from a possible breathing emergency.
If your baby struggles for each breath, has blue or grey lips or tongue, stops breathing, or is floppy or difficult to wake, call your local emergency number immediately. Do not wait to check other symptoms.
Signs that need emergency help
Severe baby breathing difficulty can worsen rapidly, particularly in very young infants. Call emergency services if:
Your baby is gasping, choking, barely able to cry, or seems exhausted by the effort of breathing.
Skin beneath or between the ribs pulls sharply inward with each breath, or the head repeatedly bobs as the baby inhales.
The lips, tongue or face turn blue, grey or unusually pale. On darker skin, colour changes may be easier to see on the lips, gums or tongue.
Your baby stops breathing, has concerning pauses, becomes limp or is difficult to wake.
There is persistent grunting alongside obvious breathing effort, or breathing suddenly becomes severely noisy.
These are not symptoms to monitor overnight. Tell emergency services your baby’s age, what you see and whether your baby responds to you.
How to recognise laboured breathing in a baby
Look at the ribs, neck and nostrils
With comfortable breathing, a baby’s chest and abdomen move without deep pulling around the ribs. A laboured breathing baby may draw the skin inward beneath the ribcage, between the ribs or at the base of the neck. Clinicians call this chest indrawing or retractions. Widening nostrils and rhythmic head bobbing can also indicate extra effort.
A baby’s tummy normally moves when breathing. That movement alone is not the danger sign. Repeated sucking-in beneath the ribs, especially with grunting or rapid breathing, is different. If you are uncertain whether this is happening, seek urgent medical advice.
Notice the speed and pattern
Babies generally breathe faster than adults, and their rate changes with age, activity and temperature. A calm newborn persistently breathing more than about 60 times per minute needs prompt medical assessment. A single number cannot rule out illness, and visible distress needs immediate help without counting.
To observe the rate, watch the chest rise and fall for a full minute while your baby is calm. One rise and fall is one breath. If breathing seems unusually fast, contact a healthcare professional promptly.
Listen to the sounds
Grunting on each outward breath may signal an effort to keep the lungs open. Wheezing sounds like a whistle, often on breathing out. A harsh noise when breathing in, called stridor, may indicate narrowing higher in the airway. New or persistent noises with increased effort, rapid breathing or feeding difficulty require assessment.
Feeding and behaviour offer important clues
Some infant breathing signs become obvious during feeds. A baby who repeatedly stops sucking to catch their breath, cannot finish usual feeds, or becomes exhausted during feeding may be struggling. Fewer wet nappies can suggest reduced fluid intake.
Notice changes from your baby’s usual behaviour. A weak cry, reduced activity, unusual sleepiness or difficulty waking for feeds deserves prompt medical attention. If your baby is floppy, hard to wake or struggling to breathe, call emergency services.
Very young babies can be seriously unwell without a dramatic cough. A temperature of 38°C or higher in a baby younger than three months also needs urgent medical assessment.
What breathing patterns can be normal?
Newborn breathing is not always perfectly rhythmic. Brief faster spells and short pauses may occur, particularly during sleep, without distress or colour change. Snuffling from a blocked nose is common because babies have narrow nasal passages.
But a familiar explanation should never override new warning signs. Changing colour, prolonged pauses, sustained breathing effort, poor responsiveness and trouble feeding are not reassuring. Seek advice for a worrying new pattern even if your baby seems better between episodes.
A practical check during a cold
Imagine your baby has a runny nose and sounds congested. Rather than judging by sound alone, observe them while calm. Are the ribs pulling inward? Are the nostrils flaring? Can your baby feed normally? Are their lips and tongue their usual colour? Are they alert when awake?
Looking at effort, colour, feeding and behaviour together is more useful than focusing on one sound. Severe signs require emergency help; newly fast or noisy breathing that affects feeds needs urgent clinical review.
What to do while seeking help
Keep your baby close and watch their breathing and responsiveness. Holding them upright while awake and supervised may help them settle, but does not treat respiratory distress. Do not force a feed when your baby is struggling to breathe. Follow professional advice on feeding and hydration.
For mild nasal congestion without warning signs, infant saline drops and gentle suction may help. Avoid tobacco smoke and do not give over-the-counter cough or cold medicines unless a clinician recommends them. For sleep, place your baby on their back on a firm, flat surface without pillows or wedges.
If your baby stops breathing or becomes unresponsive, call emergency services and follow the operator’s instructions, including infant resuscitation guidance if required.
What might cause breathing difficulty?
A cold can block a baby’s nose. Bronchiolitis, sometimes caused by RSV, can inflame small airways and lead to fast breathing, wheezing and poor feeding. Pneumonia and other infections are also possible. Sudden breathing trouble after choking or an allergic reaction is particularly urgent.
Related topics include RSV symptoms in babies, bronchiolitis in babies and fever in babies under three months. Never delay seeking care while trying to diagnose the cause yourself.
Frequently asked questions
How can I tell if my baby is breathing too fast?
Count breaths for a full minute while your baby is calm. Persistently more than about 60 a minute in a newborn warrants prompt medical advice. Breathing effort, abnormal colour or poor alertness can be more urgent than the number itself.
Are pauses in newborn breathing normal?
Very short pauses can occur in healthy newborns without colour or behaviour changes. Prolonged pauses, repeated worrying episodes or a change in responsiveness need immediate assessment. Call emergency services if your baby stops breathing.
Can a blocked nose make breathing sound difficult?
Yes. Congestion often causes noisy breathing. However, chest indrawing, grunting, nostril flaring, poor colour or unusual sleepiness should never be dismissed as simple congestion.
Should I wait for a fever before getting help?
No. A baby may have serious breathing trouble without fever. Seek help for concerning effort, colour, feeding or alertness. A temperature of 38°C or higher under three months is itself an urgent reason for assessment.
Recognise changes and act promptly
Increased breathing effort, changes in colour, concerning pauses, unusual sounds and difficulty feeding are the key signs to watch. Parents do not need to identify the illness before asking for help. Call emergency services for severe signs and seek prompt clinical advice for persistent or worsening changes.
