Congrats for sure! My parents adopted one of my siblings. I'm a strong supporter of it. They very nearly adopted three kids in total, which would have made for 5 of us, instead of 3, *chuckle* (the girl they adopted, had two siblings, but by the time everything was able to go through, only the youngest of the three hadn't run away and joined the military, and she was 15 or 16....)
could have been interesting, but things worked out well the way they worked out.
