Hey! Hope all is well for you and LO.
I know that babies are not supposed to watch TV or video's, but we made an exception with these videos. He knows about 200 signs now and it has really helped him bridge the gap to speaking clearly. He says 150-200 words now, but still signs, especially if we don't understand what he is saying. I tried a few different books and videos, and these were the best. We started with Baby Signing Time and progressed to some of the ones for toddlers. If you "like" them on Facebook you will get updates on sales, which are frequent and really help.
