This is interesting to me because I have the same question with my 4 1/2 year old son. He gets coughs now and then, and twice, with the cough, I've heard wheezing. On those occasions, I took him to an urgent care facility, and they've given him breathing treatments. We've followed up with his ped, and they don't believe he has asthma. They relate it more to allergies. He also has mild eczema, was allergic to dairy and soy as a baby, and has a peanut allergy. They're all related, aren't they? Or at least they can be. With the combination of all these things, I thought it certainly warranted some discussion with his ped. Again, they said they don't think he has asthma. However, the other day, just as you described, my son was horsing around, running and laughing a lot, and then came the coughing attack. I did as you did, had him sit and calm himself down, but the coughing persisted. Even a half hour or so later, he would still clear his throat a little, as if he still had some residual phlegm or something. I'm not convinced he doesn't have some form of asthma. I will not medicate him unnecessarily, but I would like a more thorough assessment so I can feel more sure about his diagnosis or lack thereof. I am looking into pediatric allergy/asthma specialists...
I'm interested in reading your responses.
