Hello.. my baby is just 2.5 months. He has been suffering from cold and cough for the past 7days.No meds have worked for him. I am really worried about him. I can't see him suffering with the runny nose and cough for so long. His paed told to wait and watch. I don't know what to do. I feel so helpless. He can't sleep properly because of this. I feel so bad watching him lkke this.
