Have a get-together with all members from all sides of the adoption triad. Enjoy the company, and give each person the opportunity to share his or her own personal experience with adoption.
I'm not sure if this means getting together with all members of our adoption triad (us, S, and S's birthfamily), or just member of the triad in general (adoptive parents, adoptee, birthfamily). In any case, we are sending S's birthmom a letter this week hoping we can get together soon. We don't know any other birthparents, so this will be our opportunity for all the members of our triad to get together.
