I found this article in Suburban Parent,"20 Activities for Grandparents to do with their Grandchildren from a distance"(http://www.fambooks.com/activities.html), my two favorities were to send a hug and a jar of m&m's to help count off the days till they get to see you.

One thing I started a couple years ago, was to read books to the kids on tapes and send the books and tapes to the kids, it was kind of cute, they had their Moms play them so many times, that they knew the books forward and back. Now with webcams we can do that online but it is still nice to be able to listen to grandma read a bedtime story.

When Matthew was born I bought a recordable frame and we took one last photo before I left and I said" I Love you Matthew and will see you real soon". Every time I come to visit he gets it and makes me listen then tells me that is me..
