We played outside most of the time (better for cleaning up messes, my dear).
Successes were rewarded with m&m's. I called her "non-successes" "learning opportunities."
note to soon-to-potty-train-mommies - I recommend Smarties instead of m&m's. I never knew that they could be so messy!
As an update: I am so proud of how great Carly is doing. She has mastered the home potty, the public potty AND the airplane potty. However, she does still have the occasional "learning opportunity" at school, but we are seeing progress there, so I know that it is just a matter of time before she is 100% "learning opportunity" free.
We could have never mastered the public potty without this beauty- a foldable, portable potty seat that is perfect for little bottoms on big potties.
