Thank you for your query on Healthcare Magic.
Your child seems to have a viral illness with upper respiratory tract
Continue Tylenol in prescribed dosage every 6th hourly depending on the presence of fever.
If there is high grade fever you can do tepid sponging with luke warm water.
For vomitings you can give ondansetron
in prescribed dose.
Try to give oral fluids and oral rehydration solutions like Pedialyte to prevent dehydration
Consult your Pediatrician
as early as possible for the examination and treatment.
Hope I have answered your query.
