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

We call it "the day you came home." So, Homecoming, maybe, if you want a real name for it? Although we really don't celebrate it. We acknowledge the day their adoptions became final and their birthdays, and another "day" seems like too much for us. (We're not good at planning celebrations, so maybe that's part of it...) I hate the term "Gotcha Day" for all adoption scenarios. IDK why, I know it's popular and widely-accepted, but it rubs me the wrong way. Maybe for the same reason that it implies receipt for property/ownership. Although I do tell my kids that they are mine forever, and I am theirs. They do own my heart. But somehow that's different....
