my 10 month old baby is having chest congestion. oOur paed has given levolin. but it does not seem to work much. only the frequency if coughing has been reduced a bit. He is basically coughing more while sleeping and due to that, he gets up coughing badly ( sometimes with vomiting) and cries. however, there is not much cough coming out. I feel the cough gets stuck in his throat or chest. Is there any effective and safe home remedy for my baby?
