Let her use the big toilet, just get her a step stool, she will love it!
Ditch the pull-ups and go all panties all the time! Make sure she gets lots of praise when she actually goes, lots of clapping, high fives all around and make sure you announce that she went to everyone who is in the house at the time. If you make it a big deal with lots of excitement she will love that too!
I had easy kids I guess, after reading about potty-training stories on here. All 3 of my kids (2 boys and a girl) were completely trained (night and day) right at or around 2 years old.
We did:
All panties/underwear all the time and never looked back & I bribed them with suckers (I used Dum-Dum suckers, they are the perfect size) & used the regular toilet w/a step stool. I also put them in sweats or leggings, no jeans with buttons, just pants that are easy to pull up and down the first couple days of all panties.
My one piece of advice: Does she wake up in the mornings or from her naps dry? If she is dry more than she is wet when she wakes up, she is for sure ready, that is how I knew my kids were ready!
Make it fun. If you feel it is beginning to be a power struggle, I would take a couple days off for a break and then start fresh again after the break!
Seriously, make it fun and relax. You really have to watch her and look for her cues that she has to go, I mean watch her like a hawk, every kid has their own pee-pee 'dance/wiggle'...watch for hers so that you know when she has to go. IMO, potty-training is more the Parents responsibility, rather than the kid...it is up to you whether she succeeds or fails and will all depend on your attitude and how you approach it and how good a job you do on watching her and making sure she gets to the bathroom in time...I also believe that once you get her to go a couple times and actually make it in time w/out having an accident is when her confidence will start to grow and she will start to get it!
Good Luck!
