Teaching our son Sign Language has been a dramatic success for us. He's 14 months old now and the last six weeks have been an explosion of communication. Two months ago he was just barely starting to use the sign for "more." Today, he knows at least 30 signs (says Mo, at least 40, says I) and is learning at least one new one a day.
Just yesterday Mo mentioned that he'd be pointing to a book and making a sign she didn't recognize. I said, show me...he'd been signing "pig" all day, a sign I'd taught him the week before, because he wanted a book about Pigs read to him.
As a new parent, I can't tell you how thrilling it is to connect with a baby, your baby, on a conceptual level...sounds silly to say, but Baby Sign Language can be about more than just "milk." We were reading "Goodnight Moon" just this evening, and my son signed "moon all done" when we got to the page where the moon was gone from the sky. That moment really sealed the deal for me. Sticking with Sign Language was the right thing for us to do.
It's not that much work to learn the signs. As you learn a few dozen, you'll see a pattern, and other signs will get easier to learn. We carry a picture dictionary around with us in the baby bag.
Sometimes folks see us sign to him in public and say "oh, is he deaf?" with a kind of worried face. We reply that we're teaching him Sign Language so we can see what's on his mind a year or two early.
There's lots of opinions about teaching kids sign language. Here's my reasoning.
What do you need to do to start signing?
There's a great Dictionary of Baby Signs (ASL) here that uses Windows Media Player. I also highly recommend the Baby Signing Time Series of DVDs, particularly Volumes 1 and 2. They are the only videos that let the baby watch.
I don't know when he'll start talking. It doesn't really matter. I'm not really sure where he is "developmentally" or what a 14 month old is supposed to be doing at this point. I figure kids all even out by the time they're 18 years old anyway. But, while we look forward to him talking, be it at two years or four years old, I've already got a way to communicate with him. I can ask him what's on his mind and he'll tell me.
