On this edition of "Is This Normal?," we field a question from a mother who just received some devastating news, her 8-year-old son was just diagnosed with cerebral palsy. Her fear is that she is not strong enough to mount this lifelong fight. Fortunately, singer David Osmond is here to help me field this question. David is the nephew of Donnie and Marie Osmond, and both David and his father Alan have MS.
