If you're not talking a quilt because of autism them maybe 2 quilts. Try one regular pretty quilt and the other a flannel quilt.
FYI, I slept with my flannel rag quilt folded in four across my feet last night. Yeah, I know it is nice down here, but at night my feet have always been cold. The folded flannel quilt did the job ... with me wearing my sleep socks, of course.
