What Does Wheezing (Whistling or Squeaky Breathing) Sound Like in a Baby?
- A soft whistling or musical sound when the child breathes out
- The sound may be heard without a stethoscope when you put your ear close to the child's chest
- The child may breathe faster than usual or seem to be working harder to breathe
- The chest may expand more than usual on breathing in, with a longer breathing-out phase
- The child may seem short of breath during activity or when excited
- Wheezing may be associated with a cold, or may occur on its own
Why Does Wheezing or Whistling Breathing Matter?
- Wheezing results from narrowing of the smaller airways in the lungs — the turbulent airflow through the narrowed passages creates the whistling sound
- Common causes in children include viral-triggered bronchiolitis, asthma, and allergic reactions
- Recurrent wheezing in a child over 1 year of age is one of the patterns that prompts evaluation for possible asthma

When Should I Be Worried About My Baby's Wheezing or Squeaky Breathing?
These are visual patterns that may deserve closer attention. This is for education only — not a diagnostic guide.
- Wheezing accompanied by fast breathing or chest retractions
- Wheezing that is present at rest even when the child is not active
- Any bluish or pale color around the lips alongside wheezing
- The child appears too tired to feed, talk, or play
- Wheezing that worsens over hours or does not improve
Wheezing combined with fast breathing, retractions, or a child who seems too tired to feed or speak are among the changes many parents bring to prompt medical attention.
