I wonder how much the feeling is one-sided. I visit my grandparents more often than they visit me (even generously discounting for physical ability, income, and the one-to-many relationship).
I think the way to measure this might be grandparents moving out of state of family (think Arizona and Florida).
Obviously the stigma of aging should get the bulk of the responsibility here.
Any got any advice on how to re-norm grandparents? I'm hesitating on moving out of state during my kids early childhood.
