Is there s magnesium supplement for small children (age 3 - 30 lbs)?

Posted by Mrs. Blue

My child suffers from extreme sensitivity to loud or high pitch sound.  I've read that a magnesium deficiency can contribute to this.  She is a fairly picky eater and I'd like to know how to get her more magnesium.  Also, I've been told that children wearing ear plugs can increase the risk of ear infection.  Is this true?
