My guy is a little younger, 26 months, and we are in Day 5 of PT. I made the mistake of letting him watch the Pull-ups DVD, ( I sent for it before I decided we weren't going to use pull-ups) because he liked hearing and doing the "Potty Dance." But even after he picked out his froggy potty (the ones that sang or flushed scared him) he just wanted to dance around it, lol : ) So I put training on the back burner a couple of weeks and we stopped watching the DVD.
He knows what "pee" and "poop" mean, he has a distinctive look when getting ready to poop, and he was taking off his diaper, all signs he is ready to train, which is what is recommended. The potty has been sitting out for him to sit on whenever he wanted, so he wouldn't be afraid of it, and Sunday morning I said "We're going to sit on the potty and try to pee or poop," and his reaction was "No!" I said, yes, and let's watch Arnold (his teddy bear) use the potty. I praised Arnold and my guy picked him up and said something like "Arnold use the potty" and then sat down. And got up, and sat down repeatedly, but I kept talking to him, directing him back to the potty, giving him books, and showing him his cute new underwear that he'll be able to wear when he starts telling me he has to go potty. He gets a sticker ~ I got the book "Big Boys Use the Potty" on Amazon.com, which includes a sticker rewards book and stickers, and it's also available for girls, too ~ each time he uses the potty, and got a Teddy Bear one when he first went pee on Day 1 and pooped on Day 4. I like that this book shows an actual boy sitting on the potty, not drawings or cartoons, as does the girl's version.

He has used the potty each day to pee at least once, and it is getting easier to get him to sit. Today when I took his diaper off he said, "The potty chair." and I said yes and he went and sat down. He went pee pee and then I could see he needed to poop and he was using incredible strength to hold it in, legs locked together at the knees, teeth clenched, buttocks tighter than a drum. I said, "Oh, good, you're going poopie!" and he said "No!" I immediately pushed down on his thighs firmly enough so he couldn't clench and he pooped almost instantaneously. (I don't ever want him to hold it in and suffer like the little ones I've read about here.) He jumped up when he'd finished, i praised him profusely, and he was quite proud of himself, whereas he'd been embarrassed the first time yesterday. Hopefully he'll remember next time that it's OK to poop in the potty : )
My point in telling you our story is that it will take some time, possibly anywhere from 3 to 6 months to get your daughter fully day trained, night training will more than likely take longer, though girls are somewhat easier to train overall. (I've trained both.) Plan on being consistent to see results, even if it seems it's taking forever. Right now you want to teach her that the potty is where she's to go rather than in her diaper, that she needs to stay seated for at least 5 minutes "to try" and if you have to tape her diapers on when you want them on her, tape them! Try wrapping the tape around at least once and fastening in the back, it's harder for them to undo, and hopefully she'll get the message and leave the tape and diapers alone. I had to resort to onesies myself, and it's hard to find them in 3T :-/ But we stopped trying to take our diapers off, even when that's all we have on, whew! : )
Set regular times tor her to sit, in the morning after breakfast, then at regular intervals throughout the day so she becomes used to doing it. Have her sit in from of a favorite TV show so her mind is not solely focused on the potty and she relaxes, that helped us. I'm trying to teach my guy it's a normal thing to do, that we all have to do it. Use the bathroom yourself when she's sitting so she sees it's not just her.
Rewards and treats don't work for all children, my guy loves stickers so he's more apt to try so he can get one. (I don't recommend M & M's or other candy as a reward myself, because i don't like to associate food with cooperation.) Sometimes going to the store and picking out new underwear to wear once they are in the habit of going potty is an incentive, (you can show her the panties while she's sitting and tell her she'll get to wear them when she starts using the potty) others benefit from seeing their peers use the potty so if you have friends with trained children spend some time together, have books that show children on the potty, if she wants to go to preschool play that up, "You have to go potty by yourself if you want to go to school, " etc. The one thing I try not to say to my guy is that he's a "big boy," because some children don't care to be "big", they're content being "little", which will make them determined NOT to use the potty. (I change the words when I read him his books and just refer to them as boys.) I tell him he's doing a good job, that I love that he's "trying" and if nothing happens that he can try a little later.
Try to find what motivates HER, and develop a schedule that works for the both of you. If you want to concentrate on certain times of the day to potty do just that. (Right now since I'm trying to get him used to the idea so I'm concentrating on the morning, in a day or two I'll introduce the afternoon, so hopefully we'll have the day covered in a few weeks.) Try not to rush her, but expect her to learn, she's capable, and don't give up. Think of YOUR rewards, no diapers, woo hoo! : )
*He just woke up from his nap and ASKED to use the potty!!!
