If I catch Billi in the act, I say NO! really loud, "bad potty!!" and then put her in the bathroom alone for a few minutes. I used to put her in her pen, but she likes it in there and hate to use her "bedroom" as punishment anyway. I don't see the point in rubbing her nose in anything, or flicking her nose- the time's I've seen people try to do that to her, I flipped my lid!

It sounds like you're being patient with you're little girl and she is trying to please you. If you catch her about to potty in the wrong spot, say bad potty and move to the right spot. It takes a ton of repetition for these little ones, but once they get it, they got it!
