Child Epilepsy-4 year old-Help. Brand new.

I am looking for help and reassurance. My four year had 2 febrile seizures 2 years apart. The second was different than the so I thought best to get neuro evaluation. After the second seizure I started watching him like a hawk and noticed he experiences espisodes in his sleep. He sits up but is not awake and figits and chews. Sometimes he kicks and thrust his body. Most times it is proceeded by a random outburst other times he moans and whines while it happens. He grimaces like he is in pain then he relaxes and either goes back to sleep or wakes up. He had abnormal EEG that showed frontal activity. My husband is in denial and wants to explain away as dreaming but I know what I am reading sounds like our son has some type of nocturnal epilepsy. We are scheduled for MRI and 24hr EEG. I know I’m not crazy. I have started recording them when I am aware and reading a lot. He was put on Briviact which caused excessive sleep and behavioral problems and we are now transitioning to Trileptal. Looking for any input. Thank you in advance.
