what do you call the day you bring your foster/adopt child home?

We call it the "day you came to stay" I celebrate with my AK and my fosters who stay a year or longer. The day is about remembering when we all first met and entered into each other's lives -whether that is forever or just a period of time - it is still a blessing to have been a part of each others lives and got a chance to meet. We celebrate our meeting each other and not focus on the circumstances; although this has always been a part of the dicussions of the day. My adopted kiddos love to hear the story of how I "got the call" and what I was doing that day before they came and how I called everyone to tell them they were coming. Its sort of like their "birth story" for our family. The kids who remember also like to tell what they were going through that day. The stories always end though with fun of getting to know each other. Its not a big hoopla. We have make your own sundaes on the "day you came to stay" and usaully I let the honoree chose the dinner. We actually do this day up more than the actual adoption day.
