Potty Training?!?!

Eliza has decided to potty train herself.  I am sooo not ready for this.  She loves being a big girl on the potty and thinks it is a really fun game.  She wasn't even two yet when all of this started!!  She wants to be just like her big sister.  She has some days were she never has a wet diaper all day and others where she is not at all interested.  If she asks to go, I take her.  But I am not really encouraging her at all.  I am not interested in doing the Houston public restroom tour.  If we are at home, that is one thing.  But out and about is another!
