Care Packages

I am in the process of preparing to send a care package to our boys on the other side of the world.  I did my research...what are good items to send, what is needed, what is the temperature, etc.  However, I am still struggling...how do I send all my love, my kisses, and my hugs to our boys?  Will the package convey how much we love them?  How much we want them home?  When I decided to send a care package, I thought it would be easy.  I mean they need everything..clothes, diapers, wipes, toys, books.  What I realized is the things that really matter...love, safety, a family...can't be packaged up and sent in a book bag.
