The other side of this is lost now. Where grandparents provide childcare before they are too old.

May parents have to first pay for childcare and then have to help out their parents.

Grandparents can be occasional babysitter, but not daily childcare provider.

They have jobs in their own, until they are too weak for those. And then, they are also too weak to be primary childcare. Mutual help do a lot, but asking them to replace childcare is unrealistic.
