So last night my three year old woke up around 1:00 AM. We were sitting on the couch and his head started shaking/trembling back and forth. I tried talking to him and asking him if he was okay but he did not respond. Once the shaking stopped I asked him if he was okay and he said yes but then it started again and he became unresponsive until the shaking resolved. It only affected his head and the overall episode was very brief. His MRI and 24 hour EEG is scheduled for next week but if anybody has some insight as to what this sounds like I would love to hear it.
