My Baby Stops Breathing Briefly (Apnea)

Editorially reviewed | Sources: AAP, AAP, NIH|Updated June 2026

The short answer

Brief pauses in breathing lasting under 10 seconds are very common in newborns and are called periodic breathing. This is a normal pattern where the baby breathes rapidly, then pauses briefly, then resumes. However, true apnea (pauses lasting 20 seconds or longer, or shorter pauses accompanied by color changes or heart rate drops) is a medical concern that should be evaluated promptly.

Thousands of parents search for this exact thing. You are not alone.

By Age

What to expect by age

0-1 month

Newborns often have irregular breathing patterns, including periodic breathing where they alternate between rapid breaths and brief pauses of 5-10 seconds. This is normal and results from the immature brainstem respiratory center. It is most noticeable during sleep. Premature babies are at higher risk for true apnea of prematurity, where pauses exceed 20 seconds or are accompanied by bradycardia (slowed heart rate) or desaturation (oxygen drops). If your newborn has pauses that seem prolonged or is turning blue, pale, or limp, seek immediate medical attention.

1-6 months

Periodic breathing typically decreases by 3-6 months as the baby's respiratory control matures. Apnea events in previously healthy infants at this age are called apparent life-threatening events (ALTEs) or brief resolved unexplained events (BRUEs). These episodes, where the baby may stop breathing, turn blue, go limp, or choke, need medical evaluation to determine the cause, which can include reflux, infection, or rarely, seizures or metabolic conditions.

6-12 months

By this age, periodic breathing is uncommon. True apnea episodes are rare and usually have an identifiable cause such as respiratory infection (RSV, bronchiolitis), seizures, or obstructive sleep apnea from enlarged adenoids or tonsils. Breath-holding spells may begin around this age, typically triggered by crying, pain, or frustration. While frightening, breath-holding spells are involuntary and generally benign, with the child resuming breathing on their own.

What Should You Do?

When to take action

Probably normal when...
  • Brief pauses in breathing lasting under 10 seconds in a newborn, followed by normal breathing, with no color change or distress (periodic breathing)
  • Occasional irregular breathing patterns during sleep in a baby under 6 months who is otherwise healthy and growing well
  • A brief breath-holding spell during crying in an older infant that resolves spontaneously within seconds
Mention at your next visit when...
  • You frequently observe breathing pauses that seem to last longer than 10 seconds
  • Your baby has had one or more episodes of turning pale or blue briefly, even if they recovered quickly on their own
  • You feel the need to stimulate your baby to restart breathing, even if they responded quickly
Act now when...
  • Your baby stops breathing for 20 seconds or more, turns blue or gray, becomes limp, or does not resume breathing on their own - call 911 immediately and begin infant CPR if the baby is not breathing
  • Your baby has repeated apnea episodes, an apnea spell accompanied by fever, vomiting, or unusual drowsiness, or an episode that required stimulation or resuscitation to resolve

Trust your instincts. If something feels wrong, reach out to your pediatrician.

Worrying about your baby means you care. That is a good thing.

My Baby's Head Shape Looks Abnormal

Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.

Achondroplasia (Dwarfism) in Babies

Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.

Adenoid Hypertrophy and Breathing

Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.

How to Advocate for Your Child's Needs

You know your child better than anyone, and your observations matter. If you feel something is not right with your child's development or health, you have every right to ask questions, request evaluations, and seek second opinions. Advocating for your child is not being difficult - it is being a good parent.

Air Quality and Baby Health

Babies and young children are more vulnerable to air pollution than adults because they breathe faster, their lungs are still developing, and they spend more time close to the ground where some pollutants concentrate. The EPA recommends keeping babies indoors when the Air Quality Index (AQI) exceeds 100 (orange level). During wildfire smoke events, keep windows closed, use air purifiers with HEPA filters, and monitor your child for coughing, wheezing, or difficulty breathing. Long-term exposure to air pollution can affect lung development.

Altitude Sickness in Babies

Babies and toddlers can experience altitude sickness when traveling above 5,000-8,000 feet (1,500-2,500 meters). Symptoms are harder to recognize in infants because they cannot describe how they feel. Watch for unusual fussiness, poor feeding, disrupted sleep, vomiting, and fast breathing. Gradual ascent is the best prevention. Most pediatricians recommend avoiding sleeping at very high altitudes (above 8,000 feet) with infants when possible, and descending immediately if symptoms appear.
