What a wonderful story.  I had read somewhere that many studies show that siblings of children with "special needs" develop a deeper sense of compassion and a greater tolerance for others with physical differences.

It also stated that many of the siblings grow up and choose a career in the health care profession and/or in the field of education.  Nobel professions to be sure. 

Have you noticed any of your children brandishing a stethoscope or a chalkboard more often then "normal"?
