I looked up some Baby Sign Language here. Also, I think I'll teach my own top ten: Jesus, eat, hurt, and so on... :) It's going to be a few months before she can say things, so I'd like her to be able to tell me somehow.
Hungry, tired , dirty diaper... she already makes signs for those. She wails after she does #2, usually in the afternoon.
I can usually see what the problem is, but I may not see things like hurting, if she has an ache or sore I didn't notice.
It will likely help with potty training. Need to study up on that, and post!
