In any event, T. and I say it back and forth like a game -- like stairway catch (it's hard for a toddler to throw a ball any distance; the stairs help if he's at the top), or running a car back and forth across a room at each other. And let me just say, there is no more rewarding exchange than this. That I know of. Saying I love you repeatedly is totally underappreciated.
Tonight, when R. was putting T. to sleep, I heard T. say it to R. Unfortunately, T.'s pronunciation is a little dodgy and takes some getting used to and R. didn't recognize it. Still, a very, very good development.
T. is consistently saying "I'm done" when he finishes eating, instead of the old stand-by, "All done" or "all gone". We got us some pronouns, yes, we do.
