My son has recently started blinking his eyes alot. He's 5 years old. Anyone has this happening to them too? Was wondering if should bring him to the doc or optometrist. It happens even when he is just talking to people and not when he's watching tv.

Can be a nervous "tick".... Always good to rule-out a physical problem first e.g. infection or sight problems. it can also be allergies. Allergies can inflame the fleshy ball between the eyes which causes excessive blinking. I had this as a kid and still blink loads as it became a habit after years of irritation. suggest see your GP/family doc or paediatrician first.
