you didn't really ask a question but nothing you have shared is that alarming. this is typical of a viral infection but as you know i have no way of blindly diagnosing or treating your grand-daughter over the internet so you will need to have her properly examined if the symptoms persist or worsen.
my three year old granddaughter has had a low grade fever for severl days mainly at nght and is saying she has a headach. she also drink alot and says her stomach hurts. she also doesn"t eat good
