Our adoption announcements came in the other day.
(it's scanned so looks a lil' crappy)
We changed his middle name and obviously his last name. Michael is after Mary's "favorite" brother and coincidentally he ended up with the same initials as me :-) She chose as our compromise of not changing his first name. Even though I fought to NOT change his name, sometimes I think, I can't believe I have a kid named Cameron. It's so not a name I would pick.
And a shout out to Picture Me Perfect that had announcements that actually fit this kind of adoption. Lots of places had adoption announcements but they were definitely for babies or even specifically for international cases.
