I've been meaning to do this for a while too, but I just finished reading an alphabet book with sienna and the lesson was struck home. What does sienna say? mostly single words, though she'll also string "please" with words or say certain phrases: "thank you" "I love you." (said that for the first time..awesome!!!). she also said "I want water" today, which was the first I had heard that. she also baby signs, please, milk, book, hi, bye, up, thank you, all done, food. but to the best of my abilities, here are the words that she says:
dada, mama, apple, boat, water, cat (meow), dog (woofwoof, bowwow), dance, egg, ball (easily her favorite word), baby, shoes, socks, feet, leg, hair, head, eye, ear, nose, mouth, cheek, teeth, toothbrush, brush, wash, push, pull, lips, toes, bracelet, filibuster, blankie,train (hoohoo) bug, bee (buzz), kiss, face, moon, star, cow (moo), elephant (pfffffth), bird, horse, hand, rock, rice, ice, milk, book, duck (quackquack), cockadoodledoo, hat, coat, shirt, buckle, bib, cheese, boot, pee (pssss), poopoo, bike, hi (with arm wave), byebye (with hand wave), up, kick, down, shhh, spaceship, all done, food, yogurt, sit, seat, bubble, walk, sssssss (when she sees a snake), fish, bear (roar), off, on, house, chalk, box, bag, backpack, yes (head nod), no (head shake), back, trash, go, pancake, car, hot, help. she also repeats a lot of words, but I haven't heard her say them independently.
laura would emphasize that 90% of the words out of her mouth are book and ball (though "no" is quickly joining the list), and that a random stranger would probably only recognize 30% (bear sounds a lot like bird, cat is sometimes tak, and I want water was ah wah wawah with the appropriate syllable emphasis to call it good in my book, and is still better than what most americans can do).
that's all for now.
