Please do not give New Brozeet without consulting her pediatrician first. Even if it worked before, her current cough might have a different cause. New Brozeet contains active ingredients like levosalbutamol (a bronchodilator) that require medical supervision and should not be self-prescribed. For a mild cold and cough, focus on keeping her hydrated, using saline nasal drops for nasal congestion, and offering warm fluids. If she develops a fever, rapid breathing, wheezing, or if the cough worsens, please have her evaluated by a doctor for an accurate diagnosis and a safe, weight-specific prescription.
