I can't say "for sure," but I think I might classify Layla's first word(s) as "All done." I say it, then she repeats it, EVERY TIME we finish a book...which she then throws on the floor. We'll see. :)
Also, lately she's taken to saying the phrase "tocka tocka tocka tocka tocka" over and over and over as she plays by herself. It's pretty cute. TOO BAD MY VIDEOS WON'T LOAD! :(
*Update*
I think her "tocka tocka tocka" MIGHT be her phrasing of "Tickle, tickle, tickle"...We have a book where you have to wake up the bunnies on each page by tickling their feet, and then they laugh. She likes to tickle the feet while I say the words, but maybe she's thinking that "tickle" goes with every book? Who knows. :)
