My healthy 5 year old began inadvertantly rolling his eyes up and to the side one week ago. his doc diagnosed it as stereotypi but i am not convinced?

Nervous tics?: Many young children get nervous habits that are not significant. Most common is rubbing the nose in the "allergic salute". Eye roll and sniffing and grimace are also very common. No reason to worry. Usually these go away or change to another form of habit as time goes on. No studies are necessary and no treatment is needed. Just maintain good health habits.
