My DS has had a cough now for about 7 weeks. Going for chest x ray this week. He doesn't have an infection and Dr can't hear anything on chest. His cough is worse at night and i wonder if dust or asthma may be a cause. I removed all teddies from his room and this seemed to help a little. We keep his room dust free but have had works done in the house a couple of months ago and this would have left a lot of residual dust in the house for a while.
What are the tell tale signs of childhood asthma?
