Just saw this in the New York Times:

A FEW months ago, while sharing a hotel room with him during a family trip, Melissa Jump noticed that her 4-year-old son was grinding his teeth at night. He had recently developed some other unnerving routines, too — organizing and reorganizing the pillows on his bed, covering his ears to block out noise (even the flushing of a toilet) and refusing to get in the car or go anywhere without his blanket.

Her pediatrician’s recommendation? A nutritional supplement (inositol, sometimes referred to as B-8) and large doses of fish oil.

“I saw a difference within a week,” Mrs. Jump said of her son, who now takes a teaspoon of fish oil, containing omega-3 fatty acids, daily. “He’s more chill; he can roll with things more. He asks about his blanket every once in a while, but it’s no big deal.”

Has anyone tried this?
