Sign language! Get Signing Time dvds. They are fantastic. My 2 1/2 year old is almost fluent (she is not autistic). There is a lot of music in the Signing Time videos that's quite catchy. My daughter hated little Einstein signing stuff, but loves Signing Time. I think they have a website www.signingtime.com. (You can see my baby signing at www.youtube.com/kpmclovin if interested). She also really enjoys a website www.starfall.com, teaches phonics and reading.
