Hi
 that sounds like a horribly stressful experience.
Both my DS and DD had 'cluster seizures' (so a few over a day and then nothing for a few weeks) from age 10 months.
They were not linked to illness or high temperatures.
DS was never medicated as they were so sporadic they decided the potential side effects of medication might outweigh the benefits.
DD had 18 seizures over 24 hours at the onset so she was put on keppra to control them. She had a couple of breakthrough seizures at which point we increased the dosage and they did an EEG which showed they started on side side of her brain which then triggered the tonic clinics.
She stayed on keppra for 3 years at which point she had been seizure free for 18 months and then weaned her off keppra and touch wood she's not had another one and she's 5, nearly 6 now.
DS just seemed to stop having the about age 2.
I much preferred it when DD was medicated as I felt they were controlled whereas I was constantly worried DS would have one at nursery / night.
They don't know what caused them but they also didn't want to call them epilepsy as apparently lots of children do outgrow them, as mine seemed to have done.
It's possible they were both just born with an hereditary low seizure threshold which increased over time.
It's hard having to wait and see what will happen, definitely ask for the details of the epilepsy nurse if there is one - ours helped me lots.
I know at the time I was desperate to hear other people's experiences of childhood seizures.
Clearly everyone's paths, diagnosis and outcomes are different, but childhood seizures are not always lifelong.
