No, thank you!

I have to admit, I pride myself on the fact that Avery is so polite. She does awesome with her please and thank you's. Lately we've been trying "No, thank you". It's so sweet to hear her say this...except with the following: Me: Avery, lets go change your stinky diaper. Her: No, thank you!! Me: You want to sit in your poops? Her: Yes, please :) LOL. Now she's playing just saying "poo poo". Just as long as she doesn't stick her hand down her pants.
