the mother of one's son- or daughter-in-law, as common grandmother of their children; the relationship between women who have grandchildren in common; maternal grandmother vis-à-vis paternal grandmother.

Talk to enough grandparents and one thing becomes clear: Because she's closer to the mother of the children, the maternal grandmother generally has a slight advantage. Or, as Audrey Berson […] put it: She's my daughter, so I have the edge. Even so, Berson's co-grandmother works in the same town as the grandkids, and she sometimes meets the bus after school. It bothers me, Berson said. I wish it were me.
