Hello there, We understand your felling and your concern towards your daughter. I is very sad that she is enduring asthma at this little age. Busty if it is not because of any Infection then it seem like it is due to allergy. When it comes to allergic bronchitis she need to continue the anti histamines and bronchodilators and all we can do is to wait and watch. You need to be more carefully at seasonal variations. Thank you
