Grandson is14 months, playing peekaboo was laughing very hard for a good 30 seconds. Out of breath, took four deep breaths after long laugh. Sounded a bit like what you would expect asthma to sound like. After the four breathes was fine. I seem to recall similar thing when I was young, maybe four years old. No respiratory at problem all. Should I seek medical advise soon or watch for repeat episodes and monitor?
Its perfectly normal to catch breath after 30 sec s of non-stop laughter. It's due to sudden and continuous intense workout of ones diaphragm and abdominal muscles. Sometimes cramps occur but subside by itself in a short while.
