Fast breathing in an infant can be a normal response or a sign of an underlying health problem. Here’s what parents should know to recognize when it’s a concern and when to seek help.
🚼 What Is Normal Breathing in Infants?
-
Newborns (0–2 months): 30–60 breaths per minute
-
Infants (2–12 months): 20–50 breaths per minute
-
Note: Infants often breathe irregularly, with occasional pauses or bursts of rapid breathing (especially during sleep). This is usually normal.
⚠️ When Fast Breathing Might Be a Concern
Fast breathing (tachypnea) can signal several conditions, especially if it comes with other symptoms:
âś… Common Causes (Non-emergency):
-
Crying or fussing
-
Fever: Increased body temperature can increase breathing rate.
-
Recent feeding: Some babies breathe faster briefly after eating.
🚨 Concerning Causes:
-
Respiratory infections (e.g., bronchiolitis, pneumonia)
-
Asthma (less common in very young infants)
-
Congenital heart disease
-
Sepsis or serious infections
-
Metabolic disorders
🚨 When to Seek Medical Help Immediately
Call your doctor or go to the ER if your baby has:
-
Breathing rate consistently over 60 breaths/min
-
Nostrils flaring while breathing
-
Grunting sounds during exhalation
-
Chest retractions (ribs or sternum pulling in with each breath)
-
Bluish lips, tongue, or skin
-
Poor feeding
-
Lethargy or difficulty waking
-
Persistent cough, wheezing, or high-pitched sounds when breathing
👩‍⚕️ What a Doctor Might Do
-
Check oxygen levels with a pulse oximeter
-
Listen to lungs and heart
-
Order a chest X-ray or lab tests
-
Monitor for dehydration or signs of infection
🏠What You Can Do at Home
-
Keep baby calm: crying can increase breathing rate
-
Track symptoms: note when it started, how fast they’re breathing, and any other signs
-
Keep baby upright: this may ease breathing
-
Avoid smoke exposure and sick contacts
Summary
Fast breathing in an infant isn’t always a medical emergency, but trust your instincts—if your baby seems unwell or you’re unsure, get checked promptly.
