Normal Baby Breathing Rate by Age

Quick take: A newborn’s normal breathing rate is 40–60 breaths per minute, while a 1-year-old’s is 24–40. Count breaths for a full 60 seconds while your baby sleeps—never during crying or fever. Fast breathing (tachypnea) in a calm infant is over 60 at birth, over 50 at 2 months, and over 40 at 1 year. If you see retractions (skin pulling between ribs), grunting, or blue lips, call your pediatrician immediately—this is an emergency.

You’re sitting in the dim nursery at 2 a.m., watching the rise and fall of your baby’s tiny chest. One breath. Two. Three. Your phone timer ticks. Forty-seven breaths in sixty seconds—is that normal? The internet says “30 to 60,” but your newborn is right at the top. Your heart races. Should you wake your partner? Call the pediatrician?

Here’s the truth: most parents count at least once in those first sleep-deprived weeks. And most of the time, the number is fine. But knowing the real ranges—and the real red flags—can turn that middle-of-the-night panic into calm confidence. Below, you’ll find the exact breathing rates for every age, how to measure them like a pro, and the three signs that mean “call now.”

We’ll also clear up the myths (no, babies don’t breathe faster in deep sleep) and walk you through a simple at-home check that takes less than a minute. Bookmark this page—it’s the 2026 complete guide every parent wishes they’d had on day one.

What is a normal breathing rate for a newborn baby in minutes?

A healthy newborn breathes 40 to 60 times per minute when calm and asleep. That’s almost once every second—so fast it can feel like a hummingbird’s wings. Pediatricians call this range “eupnea,” which simply means normal, unlabored breathing.

The American Academy of Pediatrics (AAP) and the World Health Organization (WHO) both use 40–60 as the standard for the first 28 days of life. After that, the range starts to shift downward as the lungs mature and the nervous system becomes more efficient.

One mom in our community, Sarah, described her first count: “I set the timer, watched my daughter’s belly, and got 58. My stomach dropped. But the pediatrician said, ‘That’s textbook. If she’s pink, quiet, and not working hard, you’re golden.’”

Key point: always count for a full 60 seconds. Newborns can pause for 5–10 seconds (this is called “periodic breathing” and is normal), so a 15-second count can give a false high or low number.

How many breaths per minute should a 2-month-old baby have?

Why the drop? By two months, the lungs have grown, the diaphragm is stronger, and the brain’s respiratory center has matured. The pauses between breaths also become more regular, so the breathing pattern looks smoother and less “start-stop.”

If you’re counting and get 56, don’t panic. Check for fever, crying, or recent activity—any of these can temporarily push the rate up. If your baby is asleep, calm, and afebrile, re-count after 10 minutes. If it’s still above 55, note any other symptoms (grunting, flaring nostrils, retractions) and call your pediatrician.

Pro tip: use the video on your phone. Record 60 seconds of your baby’s chest while they sleep, then play it back in slow motion. It’s easier to count and less stressful than hovering with a stopwatch.

Average breathing rate for a 6-month-old infant—and what is considered high

At six months, the normal range is 25–45 breaths per minute. The average is around 35, but healthy babies can dip to 25 during deep sleep or climb to 45 during light sleep or after a feeding.

What’s considered high? Anything over 50 breaths per minute in a calm, afebrile 6-month-old is tachypnea (fast breathing) and warrants a call to your pediatrician. Below 20 is bradypnea (slow breathing) and is also a red flag—though this is much rarer in healthy infants.

One common scenario: your baby has a cold. A stuffy nose can make breathing look faster because babies are obligate nose breathers. Before you count, use saline drops and a bulb syringe to clear the nose. If the rate is still above 50 after the nose is clear, check for retractions (skin pulling in between the ribs or under the breastbone) and listen for grunting. These are signs the lungs are working harder than they should.

Another factor: prematurity. Babies born before 37 weeks often have slightly higher rates because their lungs are still catching up. If your baby was premature, ask your pediatrician for a personalized range.

Normal respiratory rate for a 1-year-old toddler—and signs of trouble

By 12 months, the normal range is 24–40 breaths per minute. The average is around 30, but toddlers can drop to 20 during deep sleep or climb to 40 during play or fever.

Signs of trouble at this age include:

• Breathing faster than 50 breaths per minute when calm and afebrile
• Retractions (skin pulling in between ribs or under the collarbone)
• Grunting or wheezing with each breath
• Nasal flaring (nostrils widening with each breath)
• Blue or pale lips, gums, or skin
• Lethargy or difficulty waking
• Refusing to eat or drink

If you see any of these, call your pediatrician immediately. At this age, respiratory infections like RSV or pneumonia can progress quickly, so early intervention is key.

One mom, Priya, shared: “My son had a cold at 13 months. His rate was 48, but he was playing and laughing. I almost didn’t call. Then I noticed his ribs pulling in with each breath. The pediatrician said, ‘You caught it early—we’ll watch him, but he’s likely fine.’ That retractions sign saved us a scary night.”

How does a baby’s breathing rate change from birth to 2 years old?

From birth to age 2, a baby’s breathing rate steadily decreases as the lungs grow, the chest wall strengthens, and the brain’s respiratory control matures. Here’s the breakdown:

Why the slowdown? At birth, the lungs are small, the airways are narrow, and the brain’s respiratory center is still learning. By age 2, the lungs have tripled in size, the airways are wider, and the brain can regulate breathing more efficiently—even during sleep, play, or fever.

One important note: the ranges above are for calm, afebrile infants. Fever, crying, activity, and even room temperature can temporarily increase the rate by 10–20 breaths per minute. Always re-check after your baby has been calm for 10–15 minutes.

What factors affect a baby’s breathing rate—and when to worry

Several factors can temporarily alter your baby’s breathing rate. Knowing these can help you decide whether to call the pediatrician or just wait and watch.

Fever

A fever increases metabolic demand, which raises the breathing rate. For every 1°F (0.6°C) rise in temperature, expect an increase of 2–4 breaths per minute. If your baby’s fever is 101°F and their baseline rate is 40, a rate of 48 is expected. But if it climbs to 60, that’s tachypnea and needs evaluation.

Crying and activity

Crying can push the rate up to 80–100 breaths per minute. After a feeding or a bout of crying, wait 10–15 minutes before counting. If the rate is still high, check for other symptoms.

Sleep stage

During active (REM) sleep, babies breathe faster and more irregularly. During quiet (non-REM) sleep, the rate slows and becomes more regular. Always count during quiet sleep for the most accurate baseline.

Room temperature

A hot room can increase the rate slightly. Keep the nursery between 68–72°F (20–22°C) and dress your baby in light layers.

Prematurity

Babies born before 37 weeks often have higher rates because their lungs are less mature. Ask your pediatrician for a personalized range based on your baby’s corrected age (age from the due date, not the birth date).

When to worry

Call your pediatrician or seek emergency care if you see any of these:

• Breathing rate consistently above the upper limit for age (see chart above)
• Retractions (skin pulling in between ribs or under the breastbone)
• Grunting or wheezing with each breath
• Nasal flaring
• Blue or pale lips, gums, or skin
• Lethargy or difficulty waking
• Refusing to eat or drink
• Fever in a baby under 3 months (any fever in this age group is an emergency)

One dad, Mark, shared: “My 4-month-old had a cold. His rate was 52, but he was pink and playful. I almost didn’t call. Then I noticed his ribs pulling in. The pediatrician said, ‘That’s a sign his lungs are working too hard. Come in.’ Turned out he had a mild case of bronchiolitis, but we caught it early.”

How to measure a baby’s breathing rate accurately at home

Counting your baby’s breaths is simple, but a few small mistakes can give a false high or low number. Follow these steps for an accurate count every time.

Step 1: Choose the right time

Count when your baby is calm and asleep—never during or right after crying, feeding, or activity. The best time is during quiet (non-REM) sleep, about 20–30 minutes after they fall asleep.

Step 2: Get into position

Sit or stand where you can see your baby’s chest or belly clearly. Use a dim nightlight if needed—bright light can wake them. Have a timer or stopwatch ready (most phones have one built in).

Step 3: Count for a full 60 seconds

Watch the rise and fall of the chest or belly. Each rise + fall = 1 breath. Count for a full 60 seconds—never multiply a 15- or 30-second count, as babies can have irregular pauses.

Pro tip: place a light toy or tissue on the belly. The rise and fall makes it easier to count.

Step 4: Record the number and conditions

Write down the rate, the time, and whether your baby was asleep, calm, or fussy. Note any fever, recent activity, or room temperature. This helps you track trends over time.

Step 5: Re-check if the number seems off

If the rate is at the high or low end of the normal range, wait 10 minutes and count again. If it’s still off, check for other symptoms and call your pediatrician if needed.

One mom, Lisa, said: “I used to count for 15 seconds and multiply by 4. Then I read that babies can pause, so I switched to 60 seconds. My daughter’s ‘60’ turned out to be 42—much more reassuring!”

Difference between normal and abnormal breathing patterns in infants

Not all fast or slow breathing is cause for alarm. Here’s how to tell normal from abnormal patterns.

Normal patterns

• Periodic breathing: Newborns often pause for 5–10 seconds between breaths, then take a few fast breaths to “catch up.” This is normal and becomes less frequent by 6 months.
• Sighing: Occasional deep sighs are normal and help reinflate the lungs.
• Irregular rate during REM sleep: During active sleep, the rate can vary widely—this is normal.
• Fast breathing after crying or feeding: The rate can climb to 80–100, but should return to normal within 10–15 minutes.

Abnormal patterns

• Tachypnea (fast breathing): Rate above the upper limit for age (see chart) when calm and afebrile. Can signal infection, heart problems, or lung disease.
• Bradypnea (slow breathing): Rate below the lower limit for age. Rare in healthy infants, but can occur with medication overdose, brain injury, or severe infection.
• Retractions: Skin pulling in between ribs, under the breastbone, or above the collarbone with each breath. This means the lungs are working harder than they should.
• Grunting: A short, low-pitched sound at the end of each breath. This is the body’s way of trying to keep the lungs open and is a sign of respiratory distress.
• Nasal flaring: Nostrils widening with each breath. Another sign the lungs are working too hard.
• Wheezing: A high-pitched whistling sound, usually on exhalation. Can signal asthma, bronchiolitis, or other lung problems.
• Stridor: A harsh, crowing sound on inhalation. Can signal croup, a foreign body, or other airway obstruction.
• Blue or pale lips/gums: A sign of low oxygen (cyanosis) and an emergency.

If you see any of the abnormal patterns, call your pediatrician immediately. For blue lips, grunting, or severe retractions, call 911 or go to the nearest emergency room.

One reader, Aisha, shared: “My 8-month-old had a cold. I heard a wheeze and panicked. The pediatrician said, ‘Wheezing on exhale is common with colds, but if it’s on inhale or gets worse, come in.’ That distinction helped me stay calm.”

Myth vs. fact: Common misconceptions about infant breathing rates

Myth: “Babies breathe faster in deep sleep.”

Fact: Babies breathe slower in deep (non-REM) sleep and faster in active (REM) sleep. Always count during quiet sleep for the most accurate baseline.

Myth: “A breathing rate of 60 is always dangerous, no matter the age.”

Fact: For a newborn, 60 is normal. For a 6-month-old, it’s tachypnea. Always check the age-specific range.

Myth: “If my baby’s breathing rate is normal, they can’t have a serious problem.”

Fact: Some conditions, like heart defects or metabolic disorders, can cause normal breathing rates even when the baby is very sick. Always look at the whole picture—color, energy, feeding, and other symptoms.

Myth: “Counting for 15 seconds and multiplying by 4 is just as accurate as counting for 60 seconds.”

Fact: Newborns and young infants can have irregular pauses, so a 15-second count can give a false high or low number. Always count for a full 60 seconds.

Myth: “Premature babies always have higher breathing rates, so I don’t need to worry about tachypnea.”

Fact: While premature babies do have higher rates, tachypnea is still a red flag. Ask your pediatrician for a personalized range based on your baby’s corrected age.

Key takeaways

• Normal breathing rates decrease as babies grow: 40–60 at birth, 24–40 at 1 year.
• Always count for a full 60 seconds during quiet sleep—never during crying or fever.
• Fast breathing (tachypnea) is over 60 at birth, over 50 at 2 months, and over 40 at 1 year.
• Retractions, grunting, nasal flaring, and blue lips are emergency signs—call your pediatrician immediately.
• Fever, crying, activity, and sleep stage can temporarily increase the rate—re-check after 10–15 minutes of calm.
• Premature babies often have higher rates—ask your pediatrician for a personalized range.
• Use the video trick: record 60 seconds of your baby’s chest, then play it back in slow motion for an easier count.

Frequently asked questions

What is the normal breathing rate for a newborn?

The normal breathing rate for a newborn (0–1 month) is 40–60 breaths per minute when calm and asleep. This range is set by the American Academy of Pediatrics and the World Health Organization. Always count for a full 60 seconds, as newborns can have irregular pauses.

How many breaths per minute should a 3-month-old baby take?

A 3-month-old should take 35–55 breaths per minute when calm and afebrile. The average is around 45. If your baby is crying or has a fever, the rate can temporarily climb higher—wait 10–15 minutes before re-counting.

Can a baby’s breathing rate be too low?

Yes, a rate below the lower limit for age is called bradypnea and can be a red flag. For a newborn, that’s below 40; for a 6-month-old, below 25; for a 1-year-old, below 24. Bradypnea is rare in healthy infants but can occur with medication overdose, brain injury, or severe infection. If your baby’s rate is low and they’re lethargic or pale, call your pediatrician immediately.

What are the signs of rapid breathing in infants?

Signs of rapid breathing (tachypnea) include:

• Rate above the upper limit for age (60 at birth, 50 at 2 months, 40 at 1 year)
• Retractions (skin pulling in between ribs or under the breastbone)
• Grunting or wheezing with each breath
• Nasal flaring (nostrils widening with each breath)
• Blue or pale lips, gums, or skin

If you see any of these, call your pediatrician. For blue lips or severe retractions, seek emergency care.

How do I check my baby’s breathing rate at home?

To check your baby’s breathing rate at home:

1. Choose a time when your baby is calm and asleep—never during or right after crying or feeding.
2. Sit or stand where you can see their chest or belly clearly. Use a dim nightlight if needed.
3. Watch the rise and fall of the chest or belly. Each rise + fall = 1 breath.
4. Count for a full 60 seconds using a timer or stopwatch.
5. Record the number and note whether your baby was asleep, calm, or fussy. Check for fever or recent activity.
6. Re-check after 10–15 minutes if the number seems off.

Pro tip: record 60 seconds of your baby’s chest on your phone, then play it back in slow motion for an easier count.

When is a baby’s breathing rate considered an emergency?

A baby’s breathing rate is considered an emergency if you see any of these:

• Blue or pale lips, gums, or skin (cyanosis)
• Severe retractions (skin pulling in deeply between ribs or under the breastbone)
• Grunting with every breath
• Lethargy or difficulty waking
• Refusing to eat or drink
• Fever in a baby under 3 months (any fever in this age group is an emergency)

If you see any of these, call 911 or go to the nearest emergency room immediately.

When to see a pediatrician

Call your pediatrician if your baby’s breathing rate is:

• Consistently above the upper limit for their age (see chart above) when calm and afebrile
• Accompanied by retractions, grunting, nasal flaring, or wheezing
• Below the lower limit for their age and they’re lethargic or pale
• Associated with a fever in a baby under 3 months (any fever in this age group is an emergency)

Seek emergency care if you see:

• Blue or pale lips, gums, or skin
• Severe retractions or grunting
• Lethargy or difficulty waking
• Refusing to eat or drink
