How Do You Say It?

Since B is not really saying any words, we've decided we will be trying to teach him some signs, just like we did for G & K so that he hopefully won't get too frustrated trying to communicate with us and vice versa. Anyway - he's already learned "more, all done, cheese, apple, and cracker". Today he wanted to climb up and down repeatedly on the bench at the kitchen table. When he wants up he raises his arms, but when he wants down he kinda just grunts or whines. K decided she should teach him how to sign "down"....she said, "Mommy, how do you say 'down' in Baby?"
