Is It Normal for a Child to Frequently Shake Their Head?

Question

A child about to celebrate their birthday often nods or shakes their head when asked questions, as they are not yet able to express themselves with words. However, recently, they have been frequently and involuntarily shaking their heads, followed by laughter, as if they find it amusing. Even when parents try to stop them, the child continues. Is there a problem here?

Answer

If the child is just shaking their head for fun, there is usually no issue, and parents only need to provide appropriate education. However, if this behavior is unconscious, it may be necessary to consider whether the child has a tic disorder.
