I strongly suggest teaching ASL!!! We started using it at birth, but you can do it any time. They will recognize the signs before they use them.
Pick the signs you with which you want to start. We started with "milk", "eat/food" and "all done/finish" You can choose what signs you feel are most important for your family. Model, model, model. Every time you SAY the sign, show the sign. The two go hand in hand. Some people chose to do a few at a time...others do more of an immersion, it depends on your comfort level with signing.
I will suggest sticking with ASL instead of an ASL "based" system. They are NOT the same! I know one system taught here in my area teaches the sign for "brown" an "easier way for the baby". The problem is that their Baby Sign for "brown" means...um...let's just say "female dog" in ASL. Not something I'd want my boys doing in public!
