Yesterday, I told Laura as she was walking down the hallway to bother Daddy, "Come here, Laura." She immediately turned around, hooked her finger at me in the "come here" sign and then kept walking down the hall.
Today, when I was telling Grammy about this, Laura immediately hooked her finger and showed Grammy the "come here" sign.
Unfortunately, though she knows both the sign and the words and what they mean, she doesn't obey them yet.
Lots of spankings the last two days for disobeying Mom after being told not to do something. It's a long couple of years from here...
