Hello,

I have gone through your query and here is my advice.

Kindly let me know whether your daughter is having fever, any allergies, any infections,or history of fall?

Petechi can be symptom of many underlying conditions so Kindly let me know if she has any other symptoms also, so that I can help you more efficiently.

Till then watch for symptoms..like she becomes less active..high temperature..sudden increase in Petechi..breathlessness..

In any of such conditions Kindly immediately take her to the hospital.

Till then keep her well hydrated..give a balanced diet.
Take care.

Waiting for your reply..

Regards.
