Ideas for Interim Periods

Okay, this post has two-fold reasoning: I'm experiencing it and since I am experiencing it, I'm going to write about it. So, I need advice from others who have experienced it.What do you DO during the in-between visit interim periods. I'm especially looking for answers for "open endeded" periods of time. In our current situation, due to health concerns on the adoptive family's side and pregnancy issues on my side, we're not sure when the next visit will be. And I'm missing the Munchkin like mad. As such, I'm needing something healthy and constructive to do in the meantime. Suggestions welcome. :)
