I saw that, ives.
It's very difficult to be able to say really.
My first impression was that when he was sucking on the bottle he was feeling comfy and sleepy like little children do when they're doing that. His eyes are blinking.

Eye rolling _can_ be a tic. My son has never had seizures but had a lot of eye tics indeed. He even had eye tics where one eye went one way and the other eye went the other. Eye tics generally are a pretty common tic too from what I've seen in the TS community. My son's eye rolling and deviations lasted months but went away. His core eye tics still remain to this day although they're pretty mild now. Opthamologist said there was absolutely nothing wrong with his eyes, his eye muscles or anything else. He also wasn't having seizures. Eye tics, because they can be a sign of something else, are something that really needs the investigation that you're getting with the EEG although I don't know too much about that

Common Tics
Those lists are just guides, they don't include all possible tics.

Rolling of eyes and those other things _can also_ be part of seizures. You're doing the right thing to sort it out. However, those eye rolling and other eye movements CAN also be tics.
