A favorite activity of many grandparents is snuggling up with the little ones for a bedtime story. While you may have very few chances to snuggle in person, you can still share a storybook. Then send the video, and the book, off to the grandkids. Buy a copy of the book for each child's household and make copies of the tape. The children will love reading along with grandma on the video.
Video cameras are wonderful tools.
You can share your favorite hobbies and lifestyle via the video tape. Take the camera on a tour of the gardens. Show how you plant, weed and harvest, or how butterflies and hummingbirds love your flowers. Whip up your famous chocolate chip cookies in front of the camera, then ship off the baked end results, and the tape. When visits can be arranged, keep in mind that the children might be wary and need some time to warm up to you.
