Our only DGC live on the west coast of the USA. They're now 13 &11 and we've seen them every year of their lives - sometimes twice a year. From the start, we were determined that DGC would know us, and we them, and we have achieved this in a very positive way. This continues to be a regular and ongoing commitment in itself. DH & I both retired "early" and have visited often - making it clear to DS that were spending his inheritance! (DiL and DS have always been positive and encouraging about our visits - we know that we're very fortunate in this regard. Even then, it's not always easy, and it requires a lot of patience to be staying in your childs home! Though we never stay with them for the whole trip.) We do Skype - earlier Skyping, when they were younger, was always supported by their parents, so that they learned how to Skype "properly". I advise sending letters, cards, postcards and parcels, (children love to receive items by post) as well as regular emails/photos. Also phone calls can sometimes be better than a Skype. Like all relationships, long distance grandparenting requires work - but it's very worthwhile. Good luck!
