[/INST] Hello, It seems your daughter is having bouts of bronchospasm that could be related to viral infections. Viral induced bronchospasm is not uncommon. Also, if you think she has a specific  allergy, then skin prick testing would be helpful to know this as specific avoidance advice could then be provided. A trial of regular bronchodilators (salbutamol or salbutamol plus streoid inhalers) is recommended. </s>
