I'm an expat, so all of my family lives across the pond (and even then there aren't that many of them, realistically my DM and some cousins).
My DHs family lives 8 hours away from us. Yea, he has a sister that is local to us, but we see her once a year for a couple of hours.
So in summary, no cousins, no uncles/aunties, the grandmothers see him once a year (for days/weeks) and one grandfather is dead, and one is in jail (I normally say he's dead, although my DD knows that's not necessarily true).
He has three older siblings, so I'd like to think that's enough. However, he keeps saying he talks/plays with his cousins/grandmas/grandpas so it makes me think he actually wants the interaction.
He's just turned 5 and started school this September.
