my daughter was frequently suffering with cough and cold at nights she coughes and vomits we consulted doctors but they said it was normal but we are so worrying in this winter it was too hard for us

A. Severe cold and cough or prolonged or continuous is basically associated with allergy I believe you should get an allergy test done for your child and consultant allergists for that they will check your child and they will advise with the right treatment for the problem
