We have no grandchildren, yet. I do know that this year in my kdg classroom, 6 of my 17 students are being raised by grandparents (with full custody). I know of 3 more who stay with grandparents for after-school care. I do think it shows a growing trend. As a previous poster said, none of us knows what the future will bring. I am very close to retirement and, if my son and DIL have children, I would be very willing to provide child care for them. It is so difficult to find reasonably priced and good childcare these days.
