Lillie has gone once last night, and 3 times today. She's had no accidents so far! She gets to play with her new toys only while she's on the pot, and gets an M&M every time she goes. A few different people told me to have her start out wearing "big girl undies" from the get-go so that when she does have an accident, she'll realize it's uncomfortable and have another incentive to get to that potty as fast as possible. I know she'll have lots of accidents in the future, but it'll be easier to clean those up now than with a newborn baby! We're using lots of positive reinforcement and crossing our fingers that this works!
Go Lillie!
