We live in Asia and our parents live in the UK and Australia.
DH's parents adore their grandchildren (toddler and baby) to the point of obsession. Mine are a bit more stand-offish.
We are having real problems keeping everyone happy. Obviously we can't afford to visit each set of grandparents each year and this has caused tension. We try to be as fair as we can. We also want time to ourselves - during the last year and a bit every single break we had was dominated by either visiting family or having them visit us (a total of 14 weeks! Much more than we would've had had we been living close to both sets of family). Visits have an intense atmosphere with a sense of having to cram as much 'quality time' together as possible.
DH's parents sulk and strop about not being "allowed" to see their grandchildren. The times they are not "allowed" are when my parents are visiting/we are visiting them, or (rare) times when the four of us spend time together as a family. My parents have a sad, martyred air of resignation.
I don't have a problem saying 'no' to either set of parents, while DH is a bit of a people pleaser. Last week we had an argument because MIL (who was here for five weeks over Christmas) is trying to book time to see us next Christmas (yes I know it's January!) and I have said we are going to see my parents. MIL is upset and angry and trying to get us to change our minds and/or commit to seeing them Christmas 2015 (ffs!). DH trying to reach a compromise.
Just offloading, really. And looking for suggestions? We have explained many times about the reality of our situation. It hasn't sunk in.
