Potty training?

Amelia has been going in the potty for probably a few months now.  Just off and on when she feels like it, nothing really set in stone.  She does love to pee and poo all over the house too.  It is getting bad.  We can not keep a diaper on her.  And we will just find little puddles of pee around the house.  Little stinker.  Well, tonight we decided to go to church instead of in the morning, so we were getting ready for church, and in a rush, we just threw everyone in the car.  When we got to church and sat down, I realized Amelia had taken off her diaper sometime before we left.  And no panties on either. And I had none in my purse.  I kept waiting for the moment when she would just start peeing all over me or Eric.  But I asked her if she had to go potty, she said yes, so I took her.  And she went!  She did great!  She also went at Target and the library this week.  She is getting there.  Now if we can just get her to keep panties or a diaper on in public!
