A check from the county?
Did she say a check from the county for their (r-word) child was supporting the family? Is that why the one sister didn't want Baby to talk or stand, perhaps?
I know a family that lives on the money from Social Security they get because one daughter is "autistic". Kid seems functional to me. Call me a hater, but I don't think they want their kid cured as long as the checks keep coming.
I didn't see this elsewhere on the forum, thought I'd throw it out there.
