I feel for ya brother. I had my first ever just this Monday. It wasn't bad, other than I had to use a bite device to hold my mouth open to different sizes (tmj sucks!).
My oldest went through the same thing, almost exactly 5 years ago to the day. She had two seizures that morning, and thankfully the EMTs witnessed the second. Then she rode a helicopter to Childrens in Dallas where she had a few more, all witnessed by doctors and nurses. We had CT scans, a MRI, and a strobe test. At least those are the ones I remember. No cause was found, and after two or so years of preventitive meds she was weened off and hasn't had one since that day. I remember it so well because she was a week shy of being 2. She'll be 7 on the 13th.
You'll all be fine. Where is she having it? I'm not too far from FTW if I can do anything to help, I'll be glad to. God bless
