“A Home for the Holidays” showcases youngsters who were featured on the show and found “forever families,” and profiles of children hoping for one. There are more than 400,000 U.S. children in foster care.

The special is presented in association with the Dave Thomas Foundation for Adoption and the Children’s Action Network.
