We are signed up for a class in April. We were told that if we started signing to her now we could expect her to start signing back in four months. Our LO is currently 4 months old.
I haven't started yet but plan to. My SIL does it with her boys and it is amazing! It makes communication so much easier and her 2 year old sounds like a 5 year old. She is also a speech pathologist so that probably has a lot to do with it as well. But I am going to follow her lead and use "please," "thank you," "all done," and "more."
