I decided to give it a try. Lucy is in underwear. She was all day yesterday, too. She had 4 pee pee accidents - which isn't horrible - I think Norah had about 12 her first day. Lucy waited until naptime, when she had a diaper on, to go poopy. I am using Nicole's technique of setting the timer - more for myself to remember to take Lucy potty. We'll see how it goes.
