My in-laws gave us the Sign with Your Baby kit (book & video) by Joseph Garcia. I really wanted the Signing Times videos, but it would have been rude to refuse the gift. How do these compare on ease of use? DD is almost 9 months old. I don't have a lot of time to study and then teach. I really would be better learning along with her and reinforcing. I have read a lot of reviews on Signing Times, but has anyone used Garcia?
