Butt Burping

Yesterday at the dr.'s office, Kai has to go to the potty. He tells the nurse and anyone that would listen "I have to pee, no actually I have to poop!" So we are in there and I am hurrying him along because the dr. is waiting. He had finished or so I thought, then he farts. We all started laughing (why is it that farting does that to people?) So he looks over and says totally matter of fact "Mom, I am not done, I still have more, it was just my butt burping!" LOL Too funny!
