Thank you for your query on Healthcare Magic.
Nothing to worry and don't be panic.
Your child seems to have a simple upper respiratory tract
infection could be due to a virus.
Continue to give paracetamol
in prescribed dosage every 6th or 8 th hourly depending on the presence of fever
For cold you can give an oral antihistamine like cetirizine
in a prescribed dosage.
If there is nose block, you can use saline nasal drops to get relief from the block.
Give plenty of oral fluids.
And consult your Pediatrician
as early as possible for the examination of the child and treatment.
Hope I have answered your query.
