When she woke up this morning, I was informed by Caroline that she is Polly, a puppy, and I am Mama Dog or Groomer Girl, depending on her needs throughout the course of the morning.
She was eating her "doggy breakfast" at the table while I was talking to Baby Dog and showing her Caroline/Polly's purple balloon.
She shouted from the dining room, "Hey! Give that back to me!"
I gave her a look and told her to try again with good manners.
She thought for a second, then tilted her head and said, "Ruff, aroo roo rrrr ruff?"
