How do we talk to our children about their friends who are sick?  I worry about their dear sweet friend.  

It is so important to teach our children compassion so they don't miss out on feeling those emotions.  It is easy to let those things slide.  Thinking it is a higher level emotion and too difficult for them to grasp.  But, one of my greatest joys is seeing my children caring for others.  Tending to their sick mom and bringing their teachers birthday presents.  I know my children have true compassion.  They may not be able to explain it or understand it, but they feel it.  So I continue to give them opportunities to practice.  (And I often reap the benefits of their thoughtfullness.)
