Knuckle-cracking by 9-year-old annoys parents


January 22, 1991|By Dr. Modena Wilsonand Dr. Alain Joffe

Q: Our 9-year-old is driving us all crazy by cracking his knuckles. How can we get him to stop?

A: Many school-age children have patterned motor habits that they repeat when under stress or during certain activities, such as watching TV.

If the habit is well-established, repeated reminders to stop often draw the child's attention to the habit and make it even more compulsive. Yell- ing or pleading will not make this habit 'N disappear.

If your son really wants to stop, ask him to come up with a plan. He might start a chart on which he can make an "X" when he gets the knuckle urge -- and then substitute some other behavior. Or consider giving him a small prize for each half-hour without cracking.

If certain activities bring the cracking on, he should avoid those activities or keep his hands busy with something else. One word of caution -- when one motor habit goes, another often takes its place. The new one may be even more obnoxious.
