Thank you for your query.
I think your child has cough
which is viral in nature.Cefodem is a safe antibiotic.Antibiotics will not work if the disease is viral.
Give your child some otrivin
baby nasal drops, mucolite
drops and servil baby syrup.She should get well in 3-4 dyas.
If you have any further queries you are free to consult me.
Hope this answers your query.
Wishing your child a speedy recovery.
Have a nice day.
