I have an 11-month-old son. In the past, I have seen him shake out of tenseness. But it has always been when he is biting down really hard on something; his bottle nipple, a toy, etc. It was as if he is exerting so much strength that he starts shaking his little head a bit. But recently I've noticed he is doing it at other times. It's not at all connected to excitement or anger. He will be nonchalantly sitting on the floor, and he will suddenly tense up his muscles to where he shakes. It only lasts about two seconds. Has anybody else had a similar experience? Is this a random tic, or could this be a more serious problem? Thank you!
