Poppy? Puppy? Poopy?

AJK has been mimicking everything anyone says. She's learning new words left and right. Unfortunately, we can't understand everything she tries to say. Lately, she's been telling us if she's pooped in her diaper. But it sounds like "poppy," which is the same word she uses for "puppy." (She loves dogs and puppies.) And sometimes she just says it for the fun of it (I think) so she walks around the house going "poppy, poppy, poppy."
Actually, I think she's a little obsessed with her bowel movements. When she poops in her diaper and I change her, she just stares at her dirty diaper going "eeeeeww! eeeeew!" and follows me into the bathroom where I flush the poop down the toilet. Before the big flush, she also peers into the toilet saying, "eeeew! eeew!"
She's been really into sitting on the toilet before bedtime every night. She's been doing so for a few minutes every night, but on Sunday she actually pooped in the toilet! I'm hoping this signals that she'll potty train early.

AJK is a girl who knows what she wants. With her not-quite-there language skills, we've run into some frustration. She points and says her version of what she wants, but if you make the mistake of giving her the wrong thing she throws it on the floor with a big "Aaaaaaaack!" Here she is with two things we know she loves.... her apple crisp snacks and her hat.
