Thank you for your query,
Your child is suffering from upper respiratory tract
infection could be due to a virus or a bacteria.
The reason may be due to spread of the infection in day care from the other children.
Continue the medication as prescribed by your Pediatrician
Take care of her at home with giving medication on time and dont send her to day care until she improves .
If you send to day care it will infect the other children.
Hope I have answered your query.
