Thank you for your query
It can be both ways. She may actually have fever which subsides by the time she reaches home. And also her agitated state can cause minor elevation in temperature. We can not rule out both possibilities. But step is to rule out all causes of fever. In her age it can be a viral fever
(especially if you belong to an endemic zone like India), urinary tract infection
, chest infections etc. You should consult a pediatrician
for the same. If rest all is ruled out you can consult a child psychologist
. Til that time you can accompany her to the school for a while. Arrange her to be brought back after half the school for a few days and gradually increase her exposure to the school rather than a sudden thing. Get more involved with her, play, make her draw or paint, some music, her hobbies, all should help. Divert her attention from the fact that she is in a new school. Make her meet her school friends outside of school like in a park or restaurant so that she familiarizes faster.
Hope all this helps
God bless you
