Try the DCN (donof conceived network), they have lots of info. I seem to remember peopke talking about "My story", and we have a book talking about all the different wats a child can come into a family by Martinez Jover ("Recipes of how babies are made"). We actually were at a book event 2 days ago and I picked up a standard " where babies come from"-type book, and discovered on a quick glick through it also had chapters on "2 mummies, 2 daddies and adoption, so it seems to be becoming more mainstream. (We live in Belgium and this book was in Dutch, I'm not sure whether it hzs been translated, but author was Pauline Oud).
