hi there: my two year old also had that. she ended up having to have an inhaler because her airways would inflate when she was active therefore causing her to have trouble breathing. after she used the inhaler for a while it went away and now she is a healthy almost 4 year old! we only ever used it the one time. i would reccomend it. good luck.
my 2 year old daughter keeps coughing to the point where she vommiting but not running a fever is that normal? . her eyes also have white stuff in them like she has pink eyes but i check and her eyes are not pink.
