A 3-week-old is sleeping quietly in a bassinet. A parent counts the breaths for one full minute and gets 52. The baby looks comfortable with no visible chest pulling or color changes.
How would you describe this breathing rate?
Baby Breathing Rate (Respiratory Rate)
Breathing rate is the number of breaths a baby takes in one minute. Babies breathe faster than adults because their lungs are smaller and still growing. Normal ranges change with age, and counting breaths when a baby is calm gives the most accurate picture.
What is a normal breathing rate for babies and young children?
- Newborns typically breathe 30 to 60 times per minute — this is much faster than an adult's 12 to 18 breaths per minute
- By 3 to 6 months, the normal range settles to 30 to 45 breaths per minute
- By 6 to 12 months, the normal range is 25 to 40 breaths per minute
- By 1 to 3 years, breathing slows to 20 to 30 breaths per minute
- By 6 to 12 years, the normal range is 14 to 22 breaths per minute
- Breathing is naturally faster when a baby is awake, active, or feeding, and slower during deep sleep
- Brief pauses of a few seconds between breaths — called periodic breathing — are common in newborns and are generally considered normal
- The best time to count breaths is when a baby is calm and resting, not during crying or feeding
What makes a baby's breathing rate speed up or slow down?
- Crying, feeding, excitement, and physical activity all raise breathing rate temporarily — this is expected and normal
- Fever raises breathing rate — for each degree Celsius of temperature rise, breathing may speed up by about 10 breaths per minute
- Viral respiratory infections such as bronchiolitis, croup, and the common cold often cause faster breathing as the lungs work harder
- Nasal congestion can make breathing sound louder and appear faster, especially in young babies who breathe mainly through the nose
- Sleep naturally slows breathing, and some variation between breaths during sleep is normal
- Pain, discomfort, or distress can temporarily raise breathing rate even without a respiratory illness
- A breathing rate that stays elevated when a baby is calm and at rest is more significant than one that rises briefly during activity
How can parents count their baby's breathing rate at home?
- Watch the chest or belly rise and fall — each complete rise-and-fall cycle equals one breath
- Count for a full 60 seconds using a clock or phone timer — a 30-second count multiplied by two is less accurate
- The best time to count is when the baby is calm, quiet, and resting — ideally during light sleep or just after settling
- Placing a hand gently on the belly can help feel each breath, especially in small babies where chest movements are subtle
- Avoid counting right after feeding, crying, or active play — these temporarily raise the rate
- Writing down the number along with the time and what the baby was doing helps track patterns to share with a doctor
What does a fast breathing rate look like in babies?
- A breathing rate above 60 breaths per minute in a baby under 2 months is fast
- A breathing rate above 50 breaths per minute in a baby 2 to 12 months is fast
- A breathing rate above 40 breaths per minute in a child 1 to 5 years is fast
- Fast breathing combined with visible effort — chest pulling in, nostril flaring, grunting, or belly heaving — means the body is working harder than usual to breathe
- Blue or gray color on the lips, tongue, or gums alongside fast breathing is a medical emergency — call 911
- Pauses in breathing lasting longer than 20 seconds, or shorter pauses with color change or limpness, need urgent evaluation
- A single elevated count during crying is less significant than a pattern of fast breathing that persists at rest
How do pediatricians check breathing rate?
- Breathing rate is one of the first vital signs measured at every well-child and sick visit
- Clinicians count breaths by watching chest or belly movements for a full minute, ideally before touching or examining the baby
- A pulse oximeter — a small painless clip placed on a finger or toe — checks oxygen levels if breathing appears fast
- Clinicians listen to the lungs with a stethoscope to check for wheezing, crackling, or reduced air movement
- Breathing rate is assessed alongside heart rate, oxygen level, feeding ability, and overall alertness
- No single number tells the full story — pediatricians look at the overall pattern of how a child breathes, feeds, and behaves

Tap the answer that best fits each scenario.
A 5-month-old has had a runny nose for two days. A parent counts the breathing rate at rest and gets 58 breaths per minute. The baby's nostrils are widening slightly with each breath and the skin between the ribs is pulling in.
What does this combination of signs describe?
A 2-year-old is running around and playing. A parent counts 38 breaths per minute. The child looks well, is playing normally, and has no color changes.
