Apparently, newborns sometimes forget to breathe especially premature babies who can experience brief pauses in breathing known as apnea of prematurity. Their nervous systems are still developing, so the brain occasionally forgets to send signals to breathe.

Why Do Newborns Sometimes Forget to Breathe? The Science Behind Apnea of Prematurity
The arrival of a newborn, especially a premature baby, brings both joy and anxiety. Parents may notice unsettling pauses in their infant’s breathing—sometimes lasting seconds—and worry something is terribly wrong. These brief interruptions, called apnea of prematurity, are surprisingly common in preterm babies. Here’s what every parent should know about why newborns “forget” to breathe and how this condition is managed.
What is Apnea of Prematurity?
Apnea of prematurity (AOP) is a developmental condition where premature infants (born before 37 weeks) experience pauses in breathing lasting 15–20 seconds or longer. Shorter pauses may coincide with a slowed heart rate (bradycardia) or low oxygen levels (desaturation). AOP affects nearly 50% of babies born before 30 weeks, making it one of the most common challenges in neonatal care.
Why Does This Happen? Blame the “Immature Brain”
The root cause lies in the baby’s underdeveloped nervous system. In premature infants:
- The brainstem (which controls automatic functions like breathing) isn’t fully mature.
- Signals to breathe may stall due to delayed reflexes.
- Muscle weakness in the airway or diaphragm can worsen pauses.
Unlike sleep apnea in adults, AOP isn’t caused by obstructions alone—it’s primarily a neurological “glitch” where the brain momentarily forgets to trigger a breath.
Common Triggers & Risk Factors
While AOP resolves as babies mature, certain factors can worsen episodes:
- Prematurity: The earlier the birth, the higher the risk.
- Infections (e.g., sepsis or RSV).
- Low blood sugar, anemia, or temperature instability.
- Reflux (GERD), which irritates the airway.
Symptoms Parents Can Observe
- Pauses in breathing lasting >15–20 seconds.
- Bluish skin (cyanosis) around lips or face.
- Grunting or limpness during episodes.
- Slow heart rate (detected via hospital monitors).
Most babies restart breathing on their own, but nurses or parents may gently stimulate them (like rubbing the back) to prompt a breath.
How Is AOP Diagnosed & Managed?
In the NICU, premature babies are monitored 24/7 with:
- Pulse oximeters (tracking oxygen levels).
- Cardiorespiratory monitors (alerting staff to pauses).
Treatment options include:
- Caffeine therapy: A low dose of caffeine citrate stimulates breathing.
- CPAP/BiPAP: Gentle air pressure keeps airways open.
- Oxygen support for severe desaturations.
- Treating underlying issues like infections or reflux.
Most infants outgrow AOP by 36–40 weeks gestational age, though some extremely preterm babies may need monitoring at home.
When Should Parents Worry?
While frightening, AOP is typically harmless if managed promptly. Seek immediate help if your baby:
- Stops breathing for >20 seconds.
- Turns blue/gray or can’t be roused.
- Has repeated episodes despite stimulation.
The Long-Term Outlook
Thankfully, apnea of prematurity rarely causes long-term harm. Studies show no increased risk of SIDS or neurodevelopmental delays in most cases. By their original due date, nearly all babies breathe steadily on their own.
Final Takeaways:
Apnea of prematurity is a temporary hiccup in a premature baby’s journey—not a reflection of their strength or future health. With expert NICU care and time, their tiny nervous systems catch up, letting them breathe (and thrive) with confidence. If you’re concerned about your baby’s breathing patterns, always consult your pediatrician or neonatologist.
