Fast Breathing in Babies: What's Normal & When to Worry | Parenting H…
Babies breathe faster than adults, but persistently fast breathing or working hard to breathe is a red flag. Learn the limits and what to do.
Babies normally breathe faster than adults. But consistently fast breathing, especially with chest sucking-in or grunting, needs urgent medical care.
Normal breathing rates
Count breaths for a full 60 seconds when baby is settled and not crying.
- Newborn: 30–60 breaths per minute
- 1–11 months: 25–40 breaths per minute
- Toddlers: 20–30 breaths per minute
What's normal — and what isn't
Healthy babies often have brief irregular patterns — faster for a few breaths, slower for a few, sometimes a pause of up to 10 seconds. This is called periodic breathing and is normal in the first months.
What's not normal: sustained fast breathing above the rates above, especially with signs of effort.
Signs baby is working hard to breathe
These are red flags — seek urgent care.
- Sucking in between the ribs, under the ribs, or above the breastbone
- Nostrils flaring with each breath
- Grunting at the end of each breath
- Head bobbing in time with breathing
- Pauses in breathing longer than 20 seconds
- Blue or grey lips, tongue or skin
- Too breathless to feed
Common causes
Fast breathing usually means baby's body needs more oxygen.
- Bronchiolitis or chest infection (most common)
- Pneumonia
- Asthma (rare in babies)
- Fever — breathing can be slightly faster with fever
- Heart conditions (rare)
When to seek urgent care
Any sign of working hard to breathe — call 000 or go straight to the emergency department. Don't wait. Trust your instinct.
When to seek help
- Sustained fast breathing at rest
- Sucking in at chest, ribs or neck
- Grunting, nostril flaring or head bobbing
- Pauses in breathing over 20 seconds
- Blue lips, tongue or skin
- Too breathless to feed
Common questions
How do I count breaths?
When baby is calm and not crying, watch the chest rise and fall for a full 60 seconds. Count one full in-and-out as one breath.
Is periodic breathing normal?
Yes — short pauses up to 10 seconds followed by faster breaths are normal in the first 3 months. Pauses longer than 20 seconds, or with colour change, are not normal.
