day my son was on a ride at the carnival he is 3 years old from the start of the ride I could tell something was wrong he wasn't smiling having fun it went around in a circle 4-5 times and I seen his eyes shut tightly almost like a twitch like he was almost about to pass out ride went around another time and I could of sworn he was about to pass out his eyes shut again and he almost leaned over I yelled stop to the person on the ride! I picked him up and he seemed to be fine but he laid his head on my chest and we left. Any idea what this could be I'm kind of freaked out.
