The whoop sound is called stridor, it's caused by turbulent airflow
through a narrowing airway. There are many reasons for airway narrowing
or collapse. A few are laryngomalacia/bronchomalacia/tracheomalacia, a
laryngeal web, subglottic stenosis, or unilateral vocal cord paralysis.
Subglottic stenosis usually causes biphasic stridor (inspiratory and
expiratory) as well as a tendency to recurrent croup, and a quiet voice.
If a vocal cord is paralyzed closed, it could affect the airway,
effectively narrowing it. Usually a baby with a paralyzed cord has a
hoarse cry. One that's paralyzed open will make swallowing difficult
when the baby lays on that side (when the paralyzed cord is down).
He could also have an undiagnosed cardiac defect that causes an
increased effort of breathing and the need for a loud, fast "catch up"
breath after any 'work', including feeding or speaking aloud.
The fact that he's unusually small could mean that he's not completely
compensating for whatever it is. Usually airway instabilities
(laryngomalacia, tracheomalacia) are outgrown by 6-24 months of age.
Interesting that this young man is still having difficulties.
