Baby dose this once and a while... (he refuses to take f/t or p/k) so if he has a good fight he gets a little wabbly after he finishes up his meal... Angle on the other hand did that "robot" after she had her first 3 meals... I wanted to see her eat so I was right there... I think it was a fear responce. She no longer does it. and I watch from behind the door ( I crack it and watch them eat. I'm odd)
