We have really been working on the signing. So far we have two signs down. We just started, so that is not too bad. She does these two on voice command only. We have been using Signing Times. We still don't have many words yet, in fact she is only making the "ma ma", "da da", "ooo" and "hmm" sounds for the most part. We get an occasional "ga ga" and "ba ba". She seems to be saying ma ma and da da discriminately, since she says it when ever she sees either of us. We are hoping that with the use of the signing, it will reinforce the speech.
