My 3 year 4 month old daughter has cough on and off since a week before Holi. She gets well when she stays home during the week but when she goes school and comes back, her cough increases. We have tried all cough syrups, home remedies, showed to doctor also in last month, he also prescribed cough syrup only. The temperature in Ahmedabad is 45+ degrees. Is it ok for the cough to come and go this often?
