My 2 year old has had an ongoing cough and the doc can't seem to pin point it. She's been only a couple different antibiotics and nothing has worked. The doc says he does them all the time, but whenever I look up anything about pediatric broncoscopies, it's rather unhappy. Is this a common thing I just need to get used to? Is it normal for this age? it's coming up awfully quickly.. just getting really nervous.
