Is it normal that newborns breathe fast?

Why This Happens

Infants have different physiological needs and lung capacities than adults, which leads to a distinct breathing pattern. Several factors may contribute to this fast or irregular pace:

• Smaller Lung Capacity: Because a baby’s lungs are much smaller, they must take more frequent breaths to get the amount of oxygen their growing body requires.
• Immature Respiratory Control: The part of the brain that controls breathing is still developing. This can result in “periodic breathing,” where a baby breathes quickly for a few seconds, pauses briefly, and then starts again.
• Increased Metabolic Demand: Newborns grow rapidly and process energy quickly, which can lead to a higher demand for oxygen and a subsequently faster heart and breathing rate.

What It Might Mean in Your Situation

When observing your newborn, it is helpful to look at the context of the breathing rather than just the speed. The meaning of fast breathing often changes based on the baby’s state and the consistency of the pattern.

For instance, if a baby is crying, feeding, or has just woken up, their breathing rate will naturally increase. This is a normal response to exertion or emotion. However, the nuance lies in the “work of breathing.” If the baby appears to be struggling to get air—rather than just breathing quickly—that is a different observation. Factors to consider include whether the breathing is consistent over several minutes, if it happens only during sleep, and whether the baby is feeding and gaining weight normally.

What To Do About It

1. Track and Time: If you are concerned about the speed, use a timer to count the breaths for one full minute while the baby is calm and sleeping. This provides an accurate number to share with a professional.
2. Observe the Chest and Nose: Watch for signs of “retractions,” where the skin pulls in around the ribs or the base of the throat with every breath, or “nasal flaring,” where the nostrils widen significantly.
3. Consult Your Pediatrician: Share your observations with your healthcare provider. You can say, “I’ve noticed the baby’s breathing seems very fast even when they are asleep; is this within the normal range for their age?”

Real-Life Example

Sarah noticed her two-week-old son was breathing very rapidly and sometimes seemed to skip a beat or two while sleeping. She felt anxious that he wasn’t getting enough air. After timing his breaths, she found he was averaging 50 breaths per minute. She called her pediatrician, who explained that this is a normal resting rate for a newborn and that “periodic breathing” is common. Sarah felt relieved knowing that as long as her son’s color remained normal and he was feeding well, the fast pace was simply part of his development.

When To Seek Outside Help

While fast breathing is often normal, respiratory issues in infants can escalate quickly. You should contact a qualified medical professional or emergency services immediately if you notice any of the following: a bluish tint to the lips or skin (cyanosis), extreme grunting sounds during breathing, deep depressions in the chest (retractions) between the ribs, or if the baby is unable to feed due to shortness of breath. In any emergency, please contact your local emergency services or go to the nearest emergency room.
