Your daughter is very young, but hey if she can do it, put the panties on her and leave them on her. Explain to her panties and diapers are not the same thing. Let her put her favorite panties on (example: princess) and say to her we want princess to stay dry. My son is a twin and is turning four in May. He refuses to try. Recently, I got fed up and I finally took his pull-up off and let him run around the house bare bottom. He then realized his safety net is GONE :-0 and suddenly he started using the potty. Amazing how that works. As soon as I knew he could do this, I put the big boy underwear on him. He was good for two weeks and then started to peepee in his underwear again. (I'm giving him some slack this week he had the flu) but as he is feeling better we are having talks again about going to the restroom again. There is no going back to pull-ups at this point.
