Clayton ended up having 5 more seizures. We spent 3 days at a Children's Hospital and he had to have an EEG, MRI, Bloodwork and a lot of waiting to rule out any problems. The last seizure was the worst, his oxygen level dropped so much he almost had to have a breathing tube placed, thankfully just an oxygen mask was enough. We got home yesterday.
The verdict is that it is a genetic disorder (I had them, so did my daughter and other family members), but they needed to be sure that was all that was going on before treating. He is now on phenobarbital and will be reevaluated in 4-6 months.
He's still the sweetest baby ever and was such a trooper through this all.
