put her in cotton underwear, not pull ups. they are too much like diapers, and kids will continue to mess them, thinking they are diapers. get an egg timer, and set it for 15 minutes. tell her when the bell dings, it's potty time. sit her on the potty for around 1-2 minutes. set the timer for that too, if you like. you don't need rewards, or treats. learning to use to potty has nothing to do with morals. there's no reason to punish them for accidents, and no reason to reward them either for peeing/pooping on the toilet. when she does pee or poop on it, just praise her, and say, "you went pee pee/poo poo on the potty. good job." when she has an accident, say, "uh oh. you had an accident. it's okay. let's go clean you up." clean her up in the bathroom, so that she gets the idea that this is where we do this. consistency is key. however, if she's not showing any interest, then i would leave it be, until she's a little older. i started my daughter at 19 months, and she's 2 months into now. it's going pretty well, but she's far from being fully trained. my goal is 2 years old for that. good luck.
