Hi thanks for contacting health care magic.... Your child according to complaint can have bronchitis or bronchiolitis like infective condition of bronchi and bronchioles... Detail physical examination with auscultation needed.... If crepitation heard and respiratory rate high pneumonia has to be ruled out.. Chest x ray might need.... Continue using antibiotic.... Here one time bleed can be from nose trauma or from above mentioned respi causes..... If bronchoconstriction present , suspected by auscultation by rhonchi then bronchodilator might given.... After completing antibiotic follow up done to your treating doctor by keeping these in mind.... Take care....
