I'm sure this won't appeal to everyone...not everybody digs morbid.
But for the curious...we were able to capture some mild spasms (this is just a snippet of what ended up being quite a long cluster involving over 20 spasms ranging from mild to moderate intensity) associated with the lip smacking & also picking at his food. I've noticed when he's in his high chair...if he stops eating & starts playing with his food...it's a cue that a cluster is coming.
I've also noticed the drama of the seizures doesn't really translate well over the video clips. Some of the spasms are as little as his eyes rolling upwards. To the untrained eye it would probably be missable.
And more. But again...I grabbed the camera after the more obvious spasms had passed. Lots of lip smacking though...
