Is there a way of finding out what may trigger wheezing , as really don't know much about this . Have been told by Dr that you can't really & that he should grow out of it . Also unsure of when to use inhaler do I give it to my son when he has cough or should it be when short of breath or daily ? Still new to this and getting him used to inhaler but he's getting there with that . Feels rotten that I don't know proper way of dealing with it .
