Does Anyone Know a Website I Can Learn Sign Language to Teach My Baby?

no my baby is not deaf but she seems open to learning. I saw the today show a while back and there was a little girl who i think was around one year old who could read. Her mother said she learned sign language first. I also wanted to know bc my sister has an autistic son who she wants to teach more sign language. He already knows some bc he doesnt talk. Thanks so much!
