My son had many bad habits including peeling his nails or skin around his nails, and funny facial expressions with his nose, mouth and neck. While these has stopped, he now has a new habit with his eyes. He winks his eyes. Not blink, but winks. It can be his right or left eye.


With previous bad habits, we just had to remind him and it soon disappear within 2 months. This time with the eye winking, it has continued for 6 months.

Anyone has any idea how to "cure" this?
