Shame people are having kids later than ever (thanks to college debt), and moving to where the jobs are, so the grandparents are older and further away than ever before.
There are many ways to encourage this. I think grandparents who can show they are providing material care to grandchildren should receive heavy tax relief, and maybe even subsidies (like a grandchild tax credit). Or, allow tax free sales of properties for grandparents to downsize go a place closer to children
