ask for 2 sibs, wait even longer?

I recently read on these threads that a couple was told by their agency that it's been "boys and siblings" coming out of Poland recently.... well, we don't have a gender preference, but we wanted to change our criteria from "1 or 2 kids" to specifically 2 siblings... and we were told that this would significantly increase our wait. On the one hand, it would certainly be easier to go from 0 to 1 than from 0 to 2 at once. I was an only child for 10 years; by the time my siblings were born, I was already into peers more than family, and I don't have any sort of special bond with my sibs, who I think often think of me as more of an aunt. I loved being the only child, getting all the adult attention. On the other hand, when I pray, I pray for "my children", not "my child" - DH and I both feel that we would want a second child if we only adopted one this time around.... but this is highly unlikely. For one thing, we don't have the money for our current adoption, much less a second one just a couple of years later. And even more importantly - I simply do not see myself going through this process ever again. We've done domestic, we've done foster care, now we're doing international. I wouldn't want to do any of those routes again. I want my privacy back. Is this just one of those "ideals" that we have to come to terms with letting go? Like the ideal of carrying your baby in your womb, etc.? Or should we hold out no matter how much longer (we started trying to adopt nearly 3 years ago) we have to wait for 2? And frankly, I don't know if 2 boys and no girls would work for me... I think I'm just looking for something to worry about since there's been a bit of a lul lately as we wait for our homestudy to be approved by our placing agency. Should we insist on 2 sibs? Or should we stick with either or and trust that if we're meant to have sibs, we'll get a referral for 2? Thanks for your feedback.
