There are significant cross-generational relationships that gamete donation has engendered that haven't yet been talked about. As donor conceived people and their donors (aka biological mothers and fathers) are finding each other more regularly through the Donor Sibling Registry and through DNA testing websites, there are members of a third generation that are also connecting- the grandparents.
There is a saying: It takes a village. Well, for our family it is literally a true statement. My husband, Eli, and I have two beautiful daughters. Milo is five years old and Demi is 19 months old. To have them, we needed to go through two surrogacy journeys with the help and support of a wonderful egg donor, two amazing gestational carriers, doctors, nurses, psychologists, social workers, attorneys and our close family, of course. Both Milo and Demi share the same egg donor and have a different biological dad; one girl is biologically Eli's and one is biologically mine.
