Hey Lexicat!
It is hard being away from family, especially during the holidays. You sound like such a sweet, nurturing parent, I'm sure you're little guy will turn out fine!

In my experience, like DreamGirl said, family is what you make of it. My husband and I live far away from both families (VLC with husband's parents and sister). It's hard to be far away and still develop that close group of people around you. We've been working on making friends and that's hard as it takes time and we live in a small town.
Is there a way you can get involved in your community and create some strong friendships? People interested in the same things your family is? Play groups? Family groups? Church or religious orgs? Maybe people who have no family around either? Is there a neighbor you could invite over for dinner?
Would your in-laws be interested in Skyping or sending letters back and forth?
Just trying to think of something helpful.
