Thanks for your query,
your daughter is having fever,diarrhea
.runny nose and cough.all this is usually viral in nature and it will take couple of days to subside.
I advise you to give paracetamol
when fever is above 100F.five plenty of fluids including oral rehydration solution sip by sip after each loose stool
give lactobicillus sachet for 2 to 3 days
For rash apply calamine
2 to 3 times a day.
In case symptoms do not settle ,take her to pediatrician
Wishing your baby good health
