Good evening hope u both recover soon . As of now isolation for both is necessary and your daughter to be taken care by other caretaker preferably . As she is close contact so there are chances she may also positive but that can be confirmed through covid test . Treatment wise children are treated symptomatically like for sneezing you can start cold medicine and for fever ,fever medicine . But don’t start any antibiotics as such without doctors advise !! Keep spo2 monitoring and temperature chart too . Any symptoms aggravating contact nearby hospital immediately . For more details contact Pediatrician .

Please consult a pediatrician via video call to get all precautionary measures u need to ensure and what all u will need to monitor would be informed to u
