Signing time: sleep

Jonah just started signing "sleep" when he's tired. When he starts getting that sleepy look to him, we just ask him if he's tired and if he wants to go to sleep and he runs his hand open-palm down the side of his face. That was crazy to not have to sign it first and have him imitate us, but for him to just do the sign when we said the word "tired"! He did it for the first time with daddy yesterday for nap time.
