I agree with what you're doing and admire that you're ready to take this to the next level and speak out.
My main thing, is I think if open/semi-open adoptions can not be made to be legally enforcable then the agencies need to start making this very clear to the expecting mom who is considering. Because in my experience they don't. In my experience they didn't inform me that in the legal sense, I have no rights to ask for the contact I was promised. I know it makes some upset when I point that out...but it's true. Sure, some adoptive couples are wonderful about it and can be trusted but since some cannot be, I think it's important that it be made very clear to any woman considering open adoption that the adoptive parents can close it anytime they want. That way, at least the mother can decide if she has enough trust to still go through with it.
