Excessive eye blinking can have a number of causes, ranging from mere fascination with the eyes to a severe medical disorder. If you are worried about your child's blinking habits, a trip to the doctor can help determine the specific cause of the excessive blinking.

Babies often have a point at which they realise that they can control their eyelids, and are fascinated with demonstrating this to themselves. This fascination will probably pass within a week or two.

Dry Eyes

Especially if your home is dry or if there is a fan typically on, excessive blinking may be your child's mechanism to rehydrate his eyes. Try turning the fans off or using a humidifier.


When excessive blinking is paired with redness or itchiness of the eyes, it may be due to allergies. An allergist can determine the specific cause and suggest medication.

Eye Tic

Sometimes children will develop a habitual tic in which they blink repetitively. You may notice that they can suppress the tic when they are focusing on it, and the tic will typically correct itself within a year.

Medical Disorders

Eye blinking can also signal a few medical disorders. Tourette's syndrome, eye abnormalities, and even brain tumours can be behind excessive blinking. Your child's doctor can evaluate the situation, especially if you notice other symptoms or more frequent blinking.
