Everything's coming up uh-oh

Maya's new saying is "uh-oh." Sometimes, she uses this word correctly:

She (intentionally) drops her cup on the floor — uh-oh!
She "accidentally" drops her dinner on the dog — uh-oh!

But more often than not, the phrase is her response to any situation:

We put her coat on — uh-oh!
She opens her toy box — uh-oh!
We change her diaper — uh-oh! (Well, sometimes that's an appropriate response).

But used correctly or not, it's pretty exciting to hear her communicate. "Uh-oh" joins her already extensive vocabulary of:

Ak (which refers to her cousin "Jack," or any photo of a boy)
Ba (when looking up, she means "balloon." Any other time, it means "book.")
Nana (Banana)
Eeeew (which means "moo," as in, the sound her stuffed animal cow makes — and sometimes, she's decided, her stuffed animal monkey, too.)
Da (Everything else)
