Because my cousin's son is deaf, and because I've heard from a number of people that teaching young children to sign just makes things easier, I've been trying to sign with Sylvia. I'm not terribly consistent, and Derrick doesn't sign with her, so I haven't had much hope that it would work. Tonight, however, after Sylvia finished her graham crackers, she brought her hands together a couple of times in a way distinctly reminiscent of the sign for "more." I'm not entirely sure she meant to sign "more," but I reinforced the sign (by giving her another cracker).
I told Derrick about it (since he's in Utah) and his response was, "Oh, is that what she's been doing when she brings her hands together." Such a punk. I think Sylvia's going to be teaching him now, though, since she's apparently learning.
