Hi, we have a 3.5 year old daughter. For the past three months she coughs every night for hours. She has blocked nose and coughs almost to the point of vomiting. We have given her antibiotics, zyrtec, ketotifen, nebulizer with Atem and different home remedies ( Vicki with socks, honey with warm water, clear soups, no diary products, wearing her multi layers of clothes, etc) but no such luck. Doctors ( so far seen 3 different one) prescribe different medicines. However they agree it is not asthma but seasonal. My wife and I are extremely worried and don't know what to do and whom to ask for advice. I know this question may have been asked numerous times but we will apreciate any insight please. Thanks
