I know this is an old thread so the original poster may not even read this, but I wanted to put out the information just in case. A great resource for adopting children with Down Syndrome from the US is the Down Syndrome Association of Greater Cincinnati. Their website is
www.dsagc.com. There is a page about adoption and you can register to be one of the families contacted when they have parents who are planning to place an infant or occasionally an older child who has Down Syndrome.
I hope that helps. Children with Down Syndrome are such a blessing!
