cough at night.
same case as me recently.
let her to go to see the doctor at once, but careful if the gp asks you to the specialist for ear nose whom always say you have to do operation if the medicine is not good (their practice) it will make you very upset/worry. In fact the problem is not so serious, find the good doctor special for the children.
(I have the case likes that recently, my daughter is now feeling better). but so pity ,she has to drink 7 bottles of medicine. take care
