Do you know ASL or use it with your LO? Please share any resources you know of that I could use to learn it and teach J!

The audiologist recommended that he learn ASL because even with the interventions we're trying his hearing will always be distorted, so I'd prefer to expose him to some form of language early on. Except if I'm going to teach him I need to get cracking on learning it too! Supposedly it's different from Baby Signs?
