Dear M.:
Your precision with observation is great and is a very helpful attribute when dealing with any health issue. If you are not doing so already, write everything you observe down and date it. Was an EEG done? If not, especially if it will be a while before you can get into the neurologist, ask your pediatrician or whoever acts as primary care to order one. (results can be sent to both the pediatricians office and the neuro.-even if you have not yet had your first visit.) Some believe that you have to wait until a child has another seizure to have validity for EEG testing; this is not true. The EEG is the basic diagnostic tool in seizure cases. Plus, a neurologist will need the info. from an EEG to make any kind of assesment.
Not all cases of seizures fit the textbook model, in fact, to some degree or other, most don't. Seizure patterns,even within individuals change, so one can imagine the differences that will occur between individuals, even those with the same type of seizures. Febrile seizures can have many triggers, from allergic reactions to illness with or without fevers or fever spikes--much of it depends upon the system of the individual.
Most of my personal experience with seizures is related to dealing with epilepsy most of my life. It was diagnosed when I was about 11, but I had seizures, largely unnoticed, for years prior to that. I have friends and relatives who have had to deal with their children's febrile seizures as well as friends that have had to deal personally with other forms of seizures.
From your post, it sounds like you are a person who seeks out knowledge, and accurate information; keep at it!
You and your family are in my prayers,
J.
