UPDATE: He got the "oh" sound on Saturday, so now he says "uh-oh" over, and over, and over.... and over again! :)
Timothy has been working on several new words lately. He now says "bye-bye" (which sounds more like "buh-buh"), "all done" (sounds like "ah nun"), and "uh-oh!", but he can't form the "o" sound yet, so he either says "uh!" and then looks at you like "I know there's more, but that's all I've got", or sometimes he says "uh-uh". He also sounded like he was working on "night-night" last night, but hasn't quite gotten there. At the rate he's going, it'll be soon, I'm sure!
