hi. If she has had at least one that does not appear fever related, I would have her evaluated by a pediatric neurologist and possibly get an EEG done. I am a registered EEG technologist and we see many many kids that have had febrile seizures. Sometimes it is just that and sometimes it can be a sign of something more underlying. An EEG will take about 2 hours at most, and although not the most fun for a 2 year old, should not be the least bit painful.
Good luck
J.
