Online group for grandparents

 Grandparents with Grandkids with Down Syndrome (GWGWDS) is a closed Facebook group:

We are an independent group of grandparents with grandchildren with Down Syndrome. We are not attached to any organization, agency, or entity. We answer to no one except ourselves. We exist to provide support, information, and education to those who want it. There are no commercial solicitations, no medical advice given, and never any derogatory comments. We welcome all grandparents worldwide with grandchildren with down syndrome without regard to race, creed, religion, or national origin.
