Primary Outcome Measures:
  • Respiratory Distress Severity Score (RDSS) [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 3 days ]
    RDSS is measured by wheezing (0, 1, 2)+ Cough (0, 1, 2)+Retraction (0, 1,2)+Respiratory rate(0,1,2)+ Oxygen saturation(0,1,2) scores

Secondary Outcome Measures:
  • average number of cough daily= as expressed parents during visits [ Time Frame: 6 months ]
    none= No cough, Mild=less than 10 daily, Severe=More than 10 daily

  • Wheezing severity in the physical examination by physician [ Time Frame: 6 Months ]
    None= no wheezing, Mild= mild expiratory, Severe= inspiratory and expiratory
