Yes, although I make up my own signs! We have two key ones in our house. Booby and finished () and ds mastered those at about 10 months. I am interested in hearing from others too.

I know some people credit early speech to signs, but from my very small circle of friends who've used it I noticed a speech delay, because the kids were so good at signing why speak iykwim? But then again, once they started speaking it was mental lol.
