What are symptoms of asthma in a 7 month old baby and how can I prevent it from coming in the future concerned as my baby always has plegm?

Cough, wheeze. Coughing , wheezing, shortness of breath are the major symptoms. Since you apparently have asthma as well, the risk for him to develop asthma is likely doubled especially if he has eczema. If your pediatrician would not intervene, you should bring him to an allergist.
