Lately, I've been noticing that Bella actually says a few words. She just doesn't always use them and refuses to say them if asked. So there's no convincing her to repeat something if I'm not sure what I've heard.
Here's a list of what I think she says and what I believe it means (some are self explanatory):
Doddy = doggy
Yoooo = hello
Pappy = patty cake
Poopoo = she lets me know when her diaper is dirty
Done = she also uses this to ask to go down from her booster seat
Buh = book (I know, now I'm just being ridiculous, but I think she really means book!!!)
