As a family we have been working to learn ASL to help Jacob better communicate with us. I bought 'Baby Signing Times' a while ago, it's a DVD that teaches simple signs for your baby. We really have loved it but we wanted to learn more signs to teach Jacob.
I was searching the Internet today for an ASL site and came across this one that's put together by Michigan State University. It is wonderful because it has a video for each sign so I know I am doing it correctly, pretty cool stuff!!
