Said my friend who's wife is pregnant. Of course I asked for this secret, and his answer was sign language because it helps them communicate. I think that could be true for earlier years, but at 20 months my lo communicates pretty well through words and pointing . The problem is more that when she says she wants something and I don't want to give it to her (example-cookies before breakfast), she throws a fit.

What do you think? Does sign language help with the terrible twos?
