Not to be alarmist... But I've also read that yawning can be a symptom of Respiratory Infection. But not always. My BPs yawn occasionally. If they have an RI, there will be other symptoms as well. So don't worry too much.
yeah they will be weezing and you will hear a popping sound coming from them. Yawning is perfectly normal (w/o weezing/popping).
