My four year girl having cold, cough and episode of asthmatic symptoms during last two years. She was nebulised with asthalin at the age of six month. However, she was well since then but at the age of three, again problem started. During last one year she had been nebulized three times with three/four round each. Last Nov,2013 she was admitted in hospital for two days for the same problem. So what should I do now?
