Potty training is in session. My daughter says we are all "on board the potty train", and she is absolutely correct, for the most part. She still prefers a pull up for her daily constitutional in our playroom which can take 45 minutes and cannot be interupted or spied upon without indignant screams. But she can stay dry all day, and even all night on occasion. Today she told me she had to go to teh bathroom, in the middle of her first feature film in a theater (Clifford), so we all paraded to the ladies room and watched as she sat on the wobbly travel seat I had in my bag. She peed in the potty and I was so PROUD!!!
My son cheers her on, (oh those boys), but he refuses. Today I paid him an M&M to sit on the potty chair. Just to sit. His sticker chart has two gimmees on it - the last of a poop I caught him in the act of taht made it to the pot... while his sisters is running out of space. SO next week I am stepping us up to underpants - no more optional pull up to catch it all neatly and make it seem more my problem than theirs.

Here is a good site with some helpful tips for those of you in this position or approaching it. As a first timer at this, I put it off out of sheer intimidation and now I know why. It tests all of your powers of negotiation, rationalization and zen mastery.
