This article is so very, very good that I could not, not post the link. Don't worry about the first paragraph - just skip down to the advice about how to encourage & support adoptive families.
It is more harsh than what I would have written but it is spot on. I hope it won't discourage but will give insight into the mind & heart of the adoptive parent. (And, yes, it is true that we all do hope you will do it too! Ha!)
